Magic pontoon steps

So inspired by a video on facebook for a very posh dock box and with Maria’s upcoming birthday on the 16th August, necessity became the mother of invention and I decided to MAKE Maria’s present this year.

Firstly, like any parent, Maria will have had presents made for her by the girls when they were very young, I am hoping that my attempts achieve the quality level that she is used to…..

In the video, some flat pack wood miraculously unfolds into two steps with a lid to a box for shoes (or more likely junk!).  The steps look very stable as she hops onto her low freeboard yacht….does she really need steps at all??  In the comments to the video there were some questions raised as to how much such a box would cost and the answer had come back as $3,000!  I have to say the box does look beautifully made but if you are willing to pay that for it, I would like to introduce myself and discuss potential charitable donations or personal investment opportunities.

So there has to be another way….. and please read to the end to see an unbelievable offer!

Mariadz, as a Moody 54, doesn’t have exceptional freeboard for her size but it is still well over a metre to the water line and nearly a metre from a floating pontoon to the deck.  Maria and I are a little vertically challenged too, which meant when I snapped my Achilles Tendon or tore Cruciate ligaments, it was tricky to get on board – in the end you have to sit on the rail and swing your legs round.

But do we need this?  At the moment we have a throne on the pontoon.  This is a huge wooden staircase to the boat that works really well but will be left when we start our travelling. So potentially we would need something for when we are travelling and Maria had taken a shine to this video when it came out. Surely I can work something out and put it together for less than that!

imageI have been fortunate to have Pete and Linda as neighboursIMG_6442 for the last two years and one of the things I have noticed as they fit out the beautiful Haven Voyager is that Pete designs a lot in cardboard before making it or buying it. This gave me the inspiration to mock up the steps prior to buying any wood or hinges!  I can also thank my son Matthew for drinking the cider that made this all possible.

The model worked really well from the wood perspective but didn’t give me a great view of the problems I was likely to have with hinges.  You need two types of hinge for this design a flush fitting hinge which helps with anything that goes out to 90 degrees and a butt hinge for joints that go out to 180 degrees.

So, here he we have the Mariadz designed Magic Pontoon Steps (patent pending 😉 ),

{drum roll please}

So what do you need to make these fine pieces of modern design?

The measurements below are based on producing steps that are 60cm tall (Height) with a first step at 30cm.  The depth (thickness) of the wood is key and I have assumed 12mm (woodwidth) but will also explain below how the sizes are made up so that people can adjust as necessary. Dimensions are Length x width and all measurements and I have rounded up the woodwidth to 15mm for calculations for ease of cutting and also because this gives a little space which the hinges are likely to require anyway.

Wood – (B&Q do a fantastic cut to size service which is very accurate)

  • The back – 60cm x 60cm [(Height) x (height)]
  • The concertina sides (4) – 60cm x 28.5cm [(Height) x (Height/2 – woodwidth)]
  • the top 1 – 60cm x 10cm [(height) x (width*7 + a bit?)] – the width is what provides the top part that closes the pack and so you want to be too much rather than too little.
  • the top 2 – 60cm x 50cm [(height) x (height – top 1 width)] – best that the top is cut from the same sheet
  • Steps (3) – 30cm x 60cm [(height/2) x height)]
  • small step sides (2) – 30cm x 30cm [(height/2) x (height/2)]
  • top bars (2) – 45cm x 45 cm [(height – top 1 width – wood width*4) x (height – top 1 width – wood width*4)]

hardware – (I chose 50mm brass hinges)

  • 10 Butt hinges
  • 14 flush hinges
  • 12mm screws (100) – check that the hinges don’t come up with 16mm screws, or you are through the wood!
  • 16mm “ish” screws (6) – these need to be less than (2*wood width)
  • magnetic catches (2)
  • anti slip tape

Considerations/Steps

20170810_164659There are basically three types of joint in the design.  The outside of the box 20170810_164715requires a joint that forms an L so that the top of the box is supported on all sides for stability.  This means that the flush hinges need to be brought in by the width of the wood and recessed into the wood to provide a flush finish (I would now recess these differently to the picture with the larger part of the hinge being recessed but I did the first as in the picture and wanted to stay consistent at least on the inside of the box).  Two of the concertina sides are joined to each side of the back using this method and the other two are joined to the top step in the same way, I used two hinges for each joint irrespective of size. Having built the U of the back and two sides and the same U shape for the front, we can join these together with the butt hinges.  You now have a box with one end which is only half covered and has the front of the top step.  We can now fit the top step itself, which is the top of the box, by fitting two flush hinges onto the top edge of the back on the outside and then the smaller top piece can be fixed.  The larger top piece is then attached to the smaller with two butt hinges (on the inside).  Our top step is taking shape.  Now to avoid any unfortunate accidents it is a good idea to attach two bars on the underside of the longer part of the top step.  These will stop the concertina collapsing inwards.  They should be mounted a wood width from the outside edge and have at least a wood width on the outside edge at the front.

Now to do the bottom step.  We already have the facing for the top step on the box so we need to make an L shape with our two remaining step pieces of wood using flush hinges and again positioning the hinge so that it forms an L when opened. Now we can join this L to the bottom edge of the top step which forms part of the box, , using the flush hinges, which should allow the entire step area to fold up to the top of the box.  The next step is to attach the small step sides to the bottom of the box under the steps so that they fold in and then come out under the steps.  In order to ensure that the bottom step sides stay in place, I used magnets on the inside of the small side pieces to lock it into the back of the bottom step.  My steps are untreated so far but the plan is to get this done too since they will be outside a lot of the time.

Finally, put anti-slip tape over the steps and top, we don’t want any accidents. At the end, you should get the following..

You can see the video was done before the protection or anti-slip was applied, I’m just a little premature I guess….. A month later, I have used International Paints Woodskin to waterproof and protect the wood, Anti Slip Strips to stop any accidents and the boat name in gold, which isn’t too clear with the wood colour unfortunately. The final element is a weathermax bag for it to go in, and I’ll probably throw some silicon sachets in there.

20170923_184350

So the steps are done.  The size works well for us since we have 90cm above the pontoon to the deck and it means three same sized steps and you are on board, probably useful that they are all the same size in case someone isn’t concentrating.  As an alternative and nearer to the example from the original video, the steps could have been a little smaller, since the overall dimensions of these steps are 60cm x 60 cm x 12cm.  It is quite easy to have the height at 40cm or 50cm, and hopefully the explanations above will help to explain how to do that.

So now for the unbelievable offer.  So anyone seeing the original video of the deck box will know it costs $3,000 (but it is a beautiful piece of art, the Rolls Royce of deck boxes).  I would be happy to make the Magic Pontoon Steps to the quality you have seen in the videos, to an agreed, realistic size, for £300 + delivery (feel free to email us at mariadz@mariadz.com).  I know, I know, I am robbing myself.  Clearly Maria’s special steps cost four times this, they are a present after all!  For those who prefer to go it alone, I hope my instructions above help.

A trip to Osea Island

With the boat back in the water and Maria’s upcoming workload as her projects go live, we had worked out that the only opportunity we had to get out for a few weeks was going to be the first weekend of August.  It had also been a long time since Lisa Jones had been with us and so we made arrangements to all get together. Lisa took Friday off work to come to the boat with the intention of getting out early for a nice weekend away.

The weather forecast was a little changeable with an element of Westerly in the wind prediction for most of the weekend.  Although the temperatures looked pretty good there was also some rain expected over the weekend so it was more with hope than expectation that we prepared for the weekend.  As usual, Maria wanted me to go to the fishing tackle shop and buy her some worms so that she go fishing over the weekend.  I may have mentioned before that this is a common request from Maria and most times there isn’t much fishing being done.  The result is I feed a lot of worms to the crabs and would have had better value for money at the fishmonger rather than the fishing tackle store! All of the other provisioning has been done, including unloading lots of stuff from the motorhome, and the boat is ready to go.

The girls are both very keen to go to Burnham or Osea Island but I am trying to tempt them with heading North for the first time.  Maybe Lowestoft or Great Yarmouth would be good destinations to try out?

Unfortunately, Maria is incredibly busy at the moment with a go live on her projects at the end of the week and so there is no let-up in her work.  So Maria is going to have to work on the Friday.  However, if she can get a free thirty minutes, we can get through the lock and she can continue to work while I sail Mariadz down the river.  We can then tie up at Halfpenny Pier in Harwich, anchor in the Orwell, moor on a buoy at Levington or start heading to our destination depending on the time.  Maria doesn’t get ten minutes to herself all day so we are stuck in our berth waiting for a window in her workload.  By 6pm, we can leave.  The first stage of the plan will therefore be a stop down the river.  We decide that a mooring buoy sounds like the best plan and head down the river at a gentle pace following a new large Fairline motor boat on its way to Southampton. IMG_6140In just over an hour we are tied up to a mooring buoy, the Prosseco has been broken out and the girls are starting to relax.  We settle down to watch the sunset over the River Orwell as our pork chops cook in the galley.  At the age of 72, Adam’s Dad has discovered Facebook.  His regular posts on the recovery of Adam’s Mum from a stroke in March, help us all understand the progress and the difficulty of these long term recoveries. It is clear from his latest update that today has been a hard day and we agree to facetime him to have a face-to-face chat over the internet. Two hours later, dinner has been switched off, alcohol has been consumed and we are all still chatting but Dad is in a better place and his favourite daughter outlaw (in joke I’m afraid) is now past eating.  A few more drinks and a bit more chatting and it is time for bed before we head to Osea Island the next day – I never get my own way 🙂

We are up at a reasonable time the next day but inexplicably seem to have run short of milk so I have to deploy and hop in the rib to pop to the shops before we can go anywhere.  Fortunately, the chandlery at Levington has a small selection of food and drink including milk so I don’t have to go too far and I am back on board and rib stowed before the girls have finished getting the rest of the boat ready for sailing.

I have an easy way to remember the tides in the North Sea, where the area fills from the North and empties to the North.  That means that prior to high tide the flow is south and after high tide it is North as the water levels lower. We are ready to leave at pretty much high tide in the morning so we will be fighting the tide all of the way.  However, the wind seems to be staying North Westerly so at least we will have some wind helping us even if it means we are slightly wind against tide with the issues with nasty waves that can be a result.  We are also getting a little more wind than the 8-10knots that we were expecting with the wind getting up to the high teens.  We are keeping the engine on and motor-sailing to ensure that we can continue to make sensible progress and will arrive early evening rather than near to sunset.  Our friends in motorboats don’t suffer from the tides like we do.  When you average seven knots, adding or subtracting up to two knots can add a lot of time to your journey.  This isn’t quite the same at 20 Knots where the impact is 10%.  We have found before that a journey that can take a couple of hours with the tide, can take four against it so we are always very watchful of the tides and try to have them in our favour whenever possible.

It doesn’t take long to get out of Harwich when you start at Levington, and we are soon heading South towards the Gunfleet windfarm and the wallet, the stretch of water between Gunfleet and the land. We are making good progress with a full mainsail out, the staysail deployed and the running backstays setup to ease any stress on the mast. Mariadz is sitting comfortably in the water as we progress through the wallet heading towards Brightlingsea.  Its about lunchtime and we have a perfectly serviceable meal from the previous night, thanks Dad!  Maria heats and freshens it up and the pork chops swimming in gravy come out with mash and veg.  It is wonderful.

As we approach the Colne Bar, the clouds are getting a little more menacing and they are some squals in the air. One of the squals is a little too close.  The rain and wind come suddenly and the wind strength rapidly goes to 40+ knots, not comfortable at all.  We try to point the bow to the wind using the autohelm so that we can take the power out of all of the sails since we still have a lot of sail out but we are heeling over quite a lot as we get there. The self tacking staysail is the problem since it adjusts itself to get the wind unless you are pretty much pointing at the wind.  As we get close to the wind direction, I free the staysail outhaul so that I can go and reel it in.  In the time it takes me to get to the stern to pull it in the leech of the sail (the edge of the sail furthest aft), has thrashed itself against the outhaul line and torn the ultraviolet protection strip.  Not a disaster but annoying and will need a repair.  The main goes in a little messily but is reefed in safely and we are back under complete control and safe.  A lightening bolt and a huge clap of thunder are very close to us but this misses us by half a mile and so not a problem for us or the couple of other yachts that we can see nearby. Then as quickly as it came onto us, the squal is gone and the wind is back to how it was.  We had been a little bit complacent about Mariadz’s capability and not as observant as we should have been but the boat had handled it fine (and safely) and we had a minor repair to remind us of our mistake.  On checking down below, all is good, so we must have stowed everything away well enough to handle a lot of movement, and the cats are not too worried.

After this bit of excitement, it takes a little time for us to get the confidence back to put more sail out again and for the rest of the trip we are very careful with a watchful eye on the sky.  There are no further surprises and we can get back to enjoying the trip. At Mersea island, we have a choice of whether to anchor in Pyefleet Creek which goes around the North of the Island or head the two hours further down the River Blackwater to Osea Island.  We agree to push on through since it is likely we will be arriving at the anchorage prior to 6pm.  If it is full, it can be very popular, then we can head back to Pyefleet.  This may also be difficult with the Brightlingsea festival on this weekend but we will see.

The River Blackwater is a lovely wide river at this point which is better for avoiding other boats than the Orwell which can be quite thin with a number of options where people could tack.  In the Orwell there have been a number of occasions when I have had to alter course multiple times to avoid a boat tacking towards me when they have tacked at unexpected points.  This is not a problem on the Blackwater where the courses are quite predictable and there is less traffic.  Although there are quite a lot of buoys that are not on the charts so you need to stay observant or you will find one going past within a few metres…..

When sailing, we always observe a radio watch on a local channel if required but also one channel 16.  This can be fun when you hear people saying “over and out” (one or the other please 🙂 ).  Some of the boats calling each other can be quite amusing too, “this is ocean dream calling St. Tropez, over”……. off the Essex coast on a bit of a dreary day! But you also hear other calls, a pan pan because someone is stuck on a sand bank but not in immediate danger and another boat that has lost their mast and rig.  A busy day on the radio and you are constantly chaning channels to see what is going on, and also to offer help if you can 🙂

Further down the River Blackwater as we make progress past Bradwell power station and Mersea island, there is a ship anchored with a red hull and a large radio mast.  6176663328_IMG_3790This is the Ross Revenge which is the boat that used to broadcast Radio Caroline in the North Sea during the Eighties.  This was after the first Radio Caroline ship, Mi Amigo, had sunk which is remarkably similar to the story for the “The Boat That Rocked”, although apparently this is a coincidence! So a little bit of history to enjoy as you sail past.  There are then a large number of moored boats before you get to the anchorage at Osea Island.  We arrive shortly before 6pm, right on low water, and with only five other boats spread around the anchorage find a good spot and start to drop anchor. In one respect arriving at low water has the advantage of simplifying the calculations for the anchor chain although it does mean that we did not benefit from the tide at any stage!

We anchor in a shade over three metres of water with another three metres being added for high tide.  We deploy about twenty five metres of chain and our long snubber 6241692640_IMG_3749although on this occasion I forget to attach the anchor ball to the anchor to help with 6241692640_IMG_3750location and retrieval in an emergency.  Time to relax again, as the sun goes down and out comes the Prosecco and the raspberry gin – hmmm, theme developing here.  Our friends are at Brightlingsea listening to music and send us a video, the singing doesn’t sound the best if we’re honest and doesn’t compare to the band we can hear on Osea Island where there must be a wedding 6241692640_IMG_3752or large summer party.  It’s a lovely, still, warm evening as we settle down.  For the second night, the fishing rods are shut firmly in their carrier and my Dad FaceTimes us and we talk for ages and Bonnie chills on deck.

Later that evening, Clyde is practicing his party trick.  6243751552_IMG_3657Maria has taught him to do a high five for treats, he likes to practice this a lot and he has the girls wrapped around his little paw! He gets treats.

It is an earlier night since we had a late one the previous night and lots of sea air and we are falling asleep long before midnight, although 6243751552_IMG_3658Clyde is now being a bit cheeky and trying his “come to bed” eyes on Lisa!

The next morning is clear with very light winds, which is pretty much as expected.  It looks like we will have to motor-sail most of the way home.  Leaving at a similar time as the previous day means we will gain the full benefit from the tide in the wallet, although we are keen to get away a little earlier so in the river we will still be fighting the tide.  The wind has picked up a but and we have a quite useable 15knots of wind which will be directly behind us as we go up the wallet.  So the plan is to motor-sail up the Blackwater, tiptoe around the Colne Bank before switching off the engine and sailing all the way home.

We set off and are accompanied by jetskis for the first part of our journey, this is one of the disadvantages of the anchorage as well as the water skiers, but they don’t do it for long and it just spoils the tranquility for a short time.  We are making good progress and arrive in the wallet as the tide turns.  For a short period the water is confused and fighting both itself and the wind but it soon works it all out and with engine off and tide with us we are sailing up the wallet at 7+ knots.  There are a few boats around us and Maria is not a racer by any means but similar to Gandalf – “You shall not pass” – when she is sailing.  There is one boat behind us with their coloured cruising chute out but 6176663328_IMG_3805they are falling behind as we start to catch up with a couple of smaller boats ahead of us. We travel up the wallet passing Walton, Frinton and Clacton which all look very different from the sea.

We are starting the turn towards Felixstowe and the wind is now directly behind us which gives an opportunity to get the sails out on both sides and sail goose winged.  We always have a gybe preventer on our main if the wind is behind at all.  This stops the boom smashing across the boat which is dangerous for the crew and also not healthy for the rig.  It is something we were taught early on and it is now a habit that we have got into.  We are still going past boats and Maria is smiling and waving, she does enjoy a nice relaxed sail.  The channel from the wallet to Felixstowe is Medusa and this is pretty much due North to the entrance.  The wind has picked up and with another change of course is now more on our beam.  I had seen this coming and had reduced sail substantially because we had noticed that the wind had been growing during our sail up the wallet.  It is now blowing between 25-35 knots which doesn’t feel so bad when you are running in front of it but after turning you suddenly feel the full force and after yesterday’s fun and games, no risks are being taken.  We are bobbing along nicely with half our main out and about the same from the headsail as we are being crossed by several boats going towards the wind, a lot more uncomfortable, bouncy and heeling over with lots of sail up. We’re grateful that we don’t need to worry about that for the rest of this journey but as we enter Felixstowe harbour, my mind does start to wander to an hour and a half away when we could be trying to get into our berth with a gusting 25-35 knot wind!  One to worry about closer to the time. This is also the time that Maria likes to get the roast dinner on, a couple of hours later we will be ready for it…

There is a large modern Southerly yacht, trying to catch us as we gently sail up the Orwell but Maria is having none of that and we hold them off until they take their sails down to go into one of the river marinas.  Its a lovely sail up the river with the wind starting to die but we are able to keep the sails up until we get close to the Orwell bridge.  Some people get frustrated at the time it takes to get through the lock and into your home berth but we find this all part of the fun and there is no major delay although we are asked to let one of the commercial boats, Orwell Lady, go into the lock first.  They must be more worried about hitting us than us hitting them :).  The two boats are the only ones in the lock and the wind has died down completely now so I had nothing to worry about.  I also clearly didn’t have anything to worry about as Maria completes the turn towards our berth and brings Mariadz home nice and gently.  I am able to get the lines on easily and the engine is off very quickly.

With the boat tied, tidied up and everything settled down, I dropped the worms over the side and fed the crabs …… again 😦

Mariadz annual lift out and through hulls

Coinciding with our annual holiday to Italy, we decided to take Mariadz out of the water to have some essential work done.  There were a number of things on our list.  Firstly, earlier in the year we had a valve for a throughhull fail and we were concerned about certain others.  With our long term plans in mind, we decided to replace all throughhulls although we thought we may salvage some of them.  With air conditioning, deck drains, engine, generator, water maker and toilets, there are twenty through hulls below the water line on Mariadz. One of these had already been done!  In addition, the keel coolers for the fridge and freezer, built in to two of the through hulls had also failed and were depressurizing our system.  So these needed to be replaced too.  While we were out it was also time to rekey the coppercoat, refresh the antifoul on key spots, check anodes, service the prop and polish the topsides.  In addition we wanted the teak to be cleaned and some internal work.  A fair amount of work to get done in three weeks.  For most of our boat owning life we have used Watercraft UK, Steve Pike, to do these jobs and we had spoken to him about doing this earlier in the year because we know how busy he gets and wanted to be sure it would get done.  Having ordered the through hulls, I spoke to Stevie to discuss the work that needed doing a few weeks before the lift out.  He was even busier than we expected and he mentioned that the through hulls would get done but that the other work would need to be “prioritised” and some of it done when the boat was back in the water and we were back from holiday.  Maria and I discussed our options and decided, on this occasion, we couldn’t afford there to be delays and issues with the work.  We spoke to Terry Clarke (Terryclarkegrp@gmail.com), a very experienced “boatie” who does a lot of work in Ipswich and has an excellent reputation.  Terry went through the list with us and agreed to pick up the work. I just had to break the news to Stevie!  That done we were ready to take Mariadz out of the water.  IMG_7589Maria was going to be busy working so I asked Phil and the team to take Mariadz out of her berth which was done professionally and carefully. As she came out, there were quite a few barnacles and weed on her.  We also checked the prop since we had quite a bit of vibration from the prop which you could hear in the aft stateroom when under power.  There were a number of barnacles on the prop which could have caused the blades to not fully deploy and hence result in vibration, so the servicing of the prop is very important and something we need to check after its service.  As part of the lift out service, Mariadz is pressure washed which cleans nearly everything off the hull and then she is put in her place for the next three weeks, as we move onto the motorhome.

The biggest and hardest job is the 20170801_115537through hull replacement and Terry and Ben get started on this first. We quickly find that the hope that we would be able to keep some through hulls or even salvage some of the existing ones.  Very quickly this became a pipe dream, as the through hulls started to come out.  20170801_131054Some of them were wobbling in place, some were becoming pink inside (a definite sign that they need changing) and some of the valves would not close properly which of course is a big issue if you needed to close these in an emergency.  20170808_125847The replacement goes really well despite some access issues and all of the through hulls are now changed.  The two in the galley which also acted as keel coolers for the refrigeration are replaced with standard large through hulls and the keel coolers are moved slightly.  These are changed from the vented coils to two porous blocks, with their own anodes, that soak up the water and cool the fridges.  Apparently this is a new 20170801_115505design which cannot be blocked by weeds etc. so we are hopeful that our fridge and freezer issues are finally solved for the last time.  Also with the removal of the temporary fan solution, the noise in the galley has also reduced.  The rekeying of the coppercoat is done with a light sandpaper after I have gone round and removed the last remnants of any barnacles on the hull.  The hull anode which was replaced earlier in the year was also reasonably worn, but with some life left in it, but we decided to change this at the same time.  The hull had been well polished and is looking fantastic.20170801_142614

Mariadz has three air conditioning units and for the last year we have had several issues with the unit in the forepeak.  In the end this was traced to a new control board unit and I had to order this from HFL in Germany, in German!  Thankfully, google translate was my friend and it was all achieved via email.  While Mariadz was out, we replaced the PCB so one of the jobs when we get back into the water is find out whether this has finally solved our aircon issue in the forepeak.

One of the final jobs was to refresh the antifoul on the keel, P bracket that holds the shaft, a part of the rudder mechanism and finally the bow thruster tunnel.  This was all done in the last few days prior to the lift back into the water.

With all of this done, we were ready to go back into the water and this was scheduled, a little later than hoped on the Wednesday following our return from holiday.  I guess it gave me an opportunity to do some of the jobs myself which will be useful in future years.

The lift back in is uneventful but before we can get back on 20170802_111418our berth we need to check for leaks and that the through hulls are seated correctly.  Terry is on board and checks all of the through hulls.  As he comes back on deck, he is pleased that out of nineteen through hulls, none of them leak.  I’m not sure I’m 100% happy with the hint of surprise in his voice….only joking, they have done a fantastic, meticulous job and it is not surprising at all. We have some minor problems with the old pipes connecting to the new through hulls but these are all addressed and there is no water coming into the boat. Interestingly, we were told that when the one through hull was done earlier in the year, the boat had to be relifted because the new one leaked which makes us even happier with our decision to use Terry!

Mariadz is returned to her berth and I can start to get the boat ready for Maria’s return.  The first job is to check that the air conditioning unit is working.  We bleed the pumps and switch them all on, after we have double checked that the though hulls are open of course! I also have a similar issue with the electric toilet where there is an air pocket in the pump and this needs to be bled.  Cleaning, putting the carpet back down and making beds before Mariadz is ship shape.

Servicing the windlass

On Mariadz, we have a 40Kg stainless Rocna anchor, that we changed soon after acquiring the Moody, and so we like to go out on anchor a fair bit. Just before we bought the Moody, the windlass failed and the previous owners had to replace it a few weeks before we took possession. IMG_5879 To be fair, it was pretty much the only thing that worked as it should when we got the boat 🙂

However, we shouldn’t get complacent about the windlass especially as that is four years ago now!  Previously I had serviced the Lewmar winches and so I was quite confident about the Lewmar windlass, especially with an electronic copy of the owner’s manual, with servicing requirements, to hand.  One of the jobs we did early on was replacing the anchor chain which is 12mm ISO (as I know now having taken apart the windlass!), with a sparkling stainless chain, eye-wateringly expensive but her ladyship demands.  The old chain had rust which had obviously flaked off as the chain was brought in which meant that the windlass is was covered in rust.  Taking the windlass apart, this was exactly what I saw.  The base of the windlass under the gypsy, that reels in the chain, was covered with rust dust, as was the gypsy itself.  I cleaned up all of the constituent parts of the windlass, much fewer than a winch.  On the gypsy the cleaning uncovered 204 which is Lewmar code for a V4 windlass, hence the 12mm chain!  Once again, I found the parts to be covered in thick grease and, like the winches, I cleaned this off and then reapplied a very thin covering of new Lewmar grease.  Putting it back together is five parts and three bolts, couldn’t be simpler. A quick test and it’s done.

Servicing the windlass is incredibly easy and like the winches rewarding.  When we go travelling we will be anchoring a lot and the windlass will be really useful.

However, you also need to have plans for how to retrieve the anchor if the windlass has failed.  The windlass does have a manual pull with the manual lock (left hand side in the picture) acting like a brake to avoid the anchor dropping again.  I think you also need a solution if the windlass is completely shot. Our solution is to use our long snubber with a hook, taken all the way back to one of the sheet winches.  This will allow us to pull up ten metres of chain at a time using a winch.  We haven’t tested this in real life yet, but the theory seems sound.

What’s that smell???

For some time Maria has been complaining that’s there is a funny smell in the saloon. It’s not there all the time and is sometimes disguised when the air freshener goes off but Maria wanted it traced. I either have to investigate the smell or buy Maria, and any guests, a nose peg!

Our friend, Mark from Motion, was on board and offered to help but little did he know that we would be doing this for hours!

We had already worked out that the smell wasn’t the grey water system and also wasn’t coming from the bilge.  When we lifted the floorboards around the holding tank, IMG_5866the smell was more pronounced. Oh dear, this is going to be nasty.  Inspection around the holding tank showed that there was no leak, that was a relief. We also knew that the holding tank was empty since we had emptied it a few weeks ago. Over the last few years we had changed a lot of the pipes, hence the white pipes in the picture. The creamy coloured pipes are the remaining pipes but these appeared to be fine with no smell coming from them.  We decide to try and trace where any gas is escaping the system by putting a fairy liquid solution across each of the pipes and around the top of the holding tank.  This reveals that the “gas” is escaping from around the sender unit that shows whether the tank is full or not.  It also revealed a small split in the pipe that led to the sea discharge, maybe this was enough to let the smell out? Rather than replacing the new and clean pipe we decided to put in a join and replace the split part with a new short length of pipe.  This was uneventful, having heated the new pipe in a pan of hot water for a couple of minutes to ensure that the 38mm pipe went onto the 40mm fitting on the holding tank…. a snug fit! But we were not convinced that this constituted the full extent of the problem. We then decided to add some water to the tank and discovered that the tank was under pressure when I opened the pump out and heard air hissing.  The setup on the Moody has two inputs from the two toilets, a deck pump out, a sea discharge and finally a breather pipe. With a breather pipe which works both ways, there should not be any pressure.  This led us to do some investigation on the breather pipe to try and understand why there is pressure.  Firstly we wanted to check that the breather pipe in the holding tank didn’t have a long downpipe (I.e. That the breather wasn’t connected to the pump out by mistake. Having checked which pipe was which and removed the tank inspection panel, it was time to hold your breath and open every window on the boat! That is definitely the smell…. but the pipes are the right way round – quick put it all back together again! Consulting the owner’s manual revealed where the breather pipe left the boat and it was interesting to see that this was a smaller pipe than the inch and a half pipe leaving the tank. A reducer somewhere perhaps? It also appeared that there was a join with another breather pipe…very confusing.  The breather pipe goes forward and we can see it doesn’t come back at hull level, so maybe The return is high and is in the headlining? Removing fifteen screws allowed us to check that this wasn’t the case! Great now to put them all back again.  But we are still confused as to how the breather is working.  We decided to force air into the breather using a footpump from the tender. There was a bubbling coming from the sink! The grey water system linked to the black water system for a breather??? Surely we would get foul smells from the sinks.  IMG_5865Tracing back the pipes revealed that the join in the breather pipes was from both grey water boxes and wasn’t linked to the black water breather at all. Back to the manual….and tracing the breather pipe forward behind the TV and up further forward. Check the hull to find a second breather, so the manual is incorrect and the pipe runs further forward. Ps, this breather isn’t the fuel breather which is adjacent to the fuel cap or the fresh water system breathers which are in the cockpit…

So we seem to be checking for a blocked breather.  Using the footpump from within the boat and we are able to push air out but it seems to take a lot of pressure. Filling the holding tank up with fresh water through the pump out resulted in water coming out of the breather.  But we have not been able to force air or wate into the breather from outside the boat.  Our current theory is that there is a flapper valve which stops water getting into the system but since it won’t have been serviced or replaced in fifteen years, then maybe it is stiff, blocked or jammed.  Our investigations continue but for the moment we don’t understand why the breather is not allowing the system to stay equalised.

Teak decks in need of a little TLC

We are big fans of teak decks although recognise that they are not everyone’s cup of tea and can get quite hot in warmer climates.  Some time ago I checked our decks which have worn away and now have 5-7mm of wood left. Apart from normal wear and tear and the slight impact of our occasional two part cleaner (wessex chemicals), this is probably just a sign of an older boat that has fifteen year old teak. One thing I did notice was a large number of exposed screw heads.20170629_102613 Some of these had clearly never been recessed,  and so we wanted to cover these with teak plugs. I had borrowed a drill bit that was 10mm wide with an extended central point that makes the hole in the fibreglass under the teak but I was keen not to drill down too deep and was concerned that I wouldn’t have enough teak to hold the screw and allow me to cover it with a teak plug.

Having found 24 exposed screws, I reviewed each one for depth and available deck thickness. For some I could use a standard 10mm wood drill bit, resink the screw and still have some room for the plug but for the vast majority, I was removing the screw, filling the hole with two part epoxy and then adding the plug. The plugs were about 15mm deep which left a fair bit of plug exposed.  The trick then is to use a very sharp chisel, correct way up (!), to knock the top off the exposed plug and make it level with the deck. Prior to doing this there are concerns around the hard wood and the force that is likely to be required to cut the plug but a gentle tap on the chisel with the palm of the hand is enough to cut the plug. Doing the same from both sides will make sure that the cut is straight and flush with the deck. Twenty-four plugs later and your done, until you walk the deck and find a few more exposed screws that you missed… when finished I went over the plugs and adjacent deck with a light sandpaper and the end result is smooth.  The plugs are brown against the grey deck but this will change over a few weeks and the end result will be a teak deck with no blemishes! I also took advantage to repair a couple fostrips of teak that were breaking and hopefully the extra strength will ensure this damage doesn’t get any worse.

In conclusion, this was one of those jobs that I was a little concerned about but actually is very simple to do and takes little time.  Using the chisel gently and taking your time seemed to get good results.  Interestingly, half way through the process there is a panic about whether the holes are too big or too small but everything falls into place and now we shouldn’t get any water coming through the deck, never mind that it just looks better.

 

Clothes Washing

Mariadz, when we first got her, had a SOBA 20170626_114401washing machine which is small and apparently designed for the yachting life.  However, Maria wanted to see if there was a portable solution that would work on the boat, in the motorhome or in Italy before the main house was finished.

In the end, washing machineshe decided on a PORTABLE 230V MINI 3KG WASHING MACHINE. so watch this space to see how this handles our motorhome holiday to Italy and a few uses on the boat during the summer…..the answer is very well.  It is slower than a normal wash because you have to manually change it from wash to spin and the load is not huge but for washing in a hot climate it seems to be a pretty good solution and got a lot of use on our recent trip to Southern Italy.

I have to say though, that I am looking to see IMG_5857whether the Drumi a low-water usage, foot-operated washer takes off. It looks a really good design but a bit pricey.  The price may come down over time so I am keeping an eye on it.

Fixing the engine – Part 4

We have done a fair bit of work on the engine over the last year and one of the last of the jobs we had identified was replacing all of the cooling hoses on the engine with new ones.  The old ones had been heat and age damaged and we thought we would take the pre-emptive step of replacing them all so that we didn’t have one go at a bad time and potentially cause damage to the engine.  At the same time, we wanted to resolve the slight oil leak at the front of the engine which we believe to be from the bolts on the engine.  We had reviewed the service manual, identified which variant of the Yanmar engine we have and then the replacement pipes had been ordered for us and we had these on the boat for quite some time before we could get the work scheduled.  Step one was to review what we had against the engine list.  We found that some of the ones we had were right but most of them were not!  Back to the drawing board on the ordering of the pipes.  We also agreed that we would get the key pipes sorted and then look at what was left after that.20170620_135019

Lindsay at Seapower has been great with us on this.  He knows our plans and knows we will have to be self-sufficient and so encourages us to get heavily involved in the work, for instance the last full service of the engine was done by me, assisted by Seapower (to make sure I didn’t mess it up!).

The pipe replacement process is quite simple but time consuming since you need to clean up where the old pipe was before you can put the new pipe in place.  20170620_134937Some of them do not have great access so someone with small hands is best.  Firstly Houghton It is very important to completely empty the coolant before you start!  We don’t want a messy bilge…. Each removed pipe is labelled so that we know what we have replaced and jubilee clips are replaced as required.  As part of this work, various engine parts were cleaned up or replaced including the thermostat.  By the end of this process we will have a pretty new engine 🙂 it takes quite a bit of time to do all of this work.

the other advantage of getting this upfront and personal with your engine is you start to see other things that need to be addressed. A missing injector clip. No pipe running an overflow to the bilge rather than letting it spray all over the top of the engine if there was a problem. Poor running of the fuel pipe too close to the gear change lever which could result in wear on the pipe.  A nice new vetus water strainer opener attached to the water strainer so that we can take the lid off without using a red rope! All of these have been addressed and i think we are now in a position where we can have a little confidence in the engine, at least until the next time we have to do something!

Yanmar engine – why maintenance is so important

Servicing the wenches (oops I mean winches)

We recognise as we go round the world that every six months or so that we will be servicing the winches.  This regime hasn’t started yet and at the beginning of the week I was still very much a wench winch virgin.

We are fortunate to count as one of our friends Mat Jerram, who is a very experienced marine engineer, and as a friend Mat has imparted knowledge normally in exchange for copious food which has been a small price to pay. So on Sunday, as Maria was making roast dinner for all of us, he raises the fact that I have been talking about servicing the winches for a couple of years….and haven’t done it yet. Maria is twenty minutes from serving so it is enough time to break apart a winch and explain what to do! Mat explains the process really well and takes a look at the winches which have clearly not been properly serviced for some time (i.e long before we had the boat). There is a mass of grease on the entire winch mechanism and I now understand the process.

So the start of a new week and new jobs.  I get the lewmar oil, grease and spare pawl springs, as recommended by Mat, and now will service all of the winches. I start with the one that Mat had broken up on Sunday on the coach roof.  It all seems to be going fine as I clean up the winch using white spirit to remove the previous grease and grime.  I am able to keep hold of the pawl springs and even they get a good clean.  The whole winch was in a pretty bad state but not disastrous or close to failure. Having cleaned everything up, I apply oil to the pawls and move them around to spread it, they are moving really freely. I then apply the grease to the rest of the mechanism, a very thin layer so that it feels greasy to the touch but you cant really see the grease on it. Everything goes back together and I test the winch – all good. The second coach roof winch is in similar condition and the process is pretty much the same apart from the ping as one of the pawl springs goes flying from my hand across the boat and into the drink! Thank you Mat for suggesting that I get some spare springs.  This winch is somewhat quicker since I know what I am doing.  Quicker but ultimately flawed since it doesn’t work when I test it!  I know exactly what I have done, one of the units with pawls could go either way and I haven’t put it back in the right way.  Of course you don’t have to take the winch half apart to change this, the whole thing has to come apart to the base plate so that you can swap the part round the other way!  Retest and success, two down….SIX to go!

I’m on a roll, so onto the big sheet winches, knock these out in a day (amongst the other things I have on) and then the four small winches should be easy.  Unscrew the cap, take off the self tail mechanism and lift the casing off the mechanism. It moves a quarter of an inch.  Stop being a wimp and lift it! Quarter of an inch again. Last try, all my strength, quarter of an inch! At this stage, you look around for something to beat the winch with in true Basil Fawlty style.  Unfortunately there are no trees in the Marina, so I will have to come up with something else.  I find a couple of blocks that I can rig as a block and tackle. and attach set this up to the boom which I have swung out and tied off above the winch.  My trusty “red rope” (previously used for lifting outboards, freeing water filter caps and pulling pipes off through hull fittings) is at the fore as the attachment to the winch.  I tie it off using a pipe hitch and a round turn and to half hitches to the block, the tail of the line is then used to provide a second lifting point on the other side of the winch so that the pull is straight up.  I am ready to go and …..success….it moves half an inch! Success is measured in degrees when you have successfully lifted the whole winch by a quarter inch on three previous attempts.  I was happy to get it to a half inch on the first attempt.  Push it back down and pull again and it goes a bit further. I continue this making more and more progress until the casing comes clear 🙂  20170615_120841I now get to see what I have to deal with… The entire mechanism is glued together with calcium, salt and lots of old grease which has hardened.  The whole thing was solid and it is difficult to see how the thing moved in the first place.20170615_224543  The bearings are equally bad with no movement.  At this point I have to admit that the act of cleaning these things up and getting them back together is incredibly therapeutic and does give a great feeling of satisfaction when it is all back together again so thoroughly recommended.  When I was young I used to try and fix broken alarm clocks.  In common with a number of people I would take them apart and put them back together again, they never worked again and there were always a few spare parts lying around at the end of the process.  It is important that this isn’t the case when rebuilding a winch! A nice way to try and stop this happening is to be very organised as the winch is taken apart.  20170615_165840I laid out paper towel on the deck and had each group of parts on a single piece.  I found this really helped to make sure that I put it back together in the same order as it came apart.  As you can see, there was a lot of work required to clean these up and the whole process, with a few interruptions, takes a number of hours.  There is no way I am getting the second one done on the same day.

The next day, I set about the other sheet winch.  I have left the block and tackle rigged, I’m clearly going to need that.  This is going smoothly and faster than the first.  I get most of it apart quite quickly and I now have to remove five bolts, with alun key holes, that hold the tower casing onto the base.  On the first winch these were tough cookies but my rachet set up is equal to the task.  I get four off with quite a bit of effort and notice that some of them are a little rounded but they are off.  The last one looks particularly tight and the hole looks even more rounded than some of the others.  Even spraying with WD40 and PlusGas does not help this one to budge and as I try to shift it the wrench twists round and the alun key shaped hole is no longer alun key shaped but round 😦  For the moment I have to clean up everything that I can and reassemble the winch but I will need to drill out the bolt to finish this winch off.

The “half” clean up goes well and the winch works again so at least I can put it back together. I receive quite a bit of advice on how to get the remaining bolt out.  Cut a slot in the top of it and use a flat head setup to get it off, the idea being there is more metal to push against.  Another is to use a “screw extraction” set, which works by burying itself in the bolt and then as you tighten (it has a reverse thread), it loosens itself.  This probably works best when the bolt is not stuck fast into the hole. I cant get the screw extraction tool to bight into the stainless steel bolt.  Time for some help.

Lindsay is on board doing some changes in the engine room, more of that later, an offers to help me drill out the bolt.  Drilling out stainless is not lightly taken on and the trick is to have the drill on a very slow setting and take your time.  We drill out quite a wide hole so that we can get a large screw extractor in there.  I had previously been using the ones that you screw into the bolt but Lindsay’s set is driven in hard.  The large one works well and the head starts to move.  Unfortunately the screw is stuck so tight that the head separates from the rest of the bolt but at least I am now in a position to get the winch apart.  We use a smaller drill to get into the screw but this is still stuck hard so we have covered it with Plusgas which should help the bolt to loosen over twenty four hours.  That said, the whole area had been lightly bathed in WD40 and plusgas for most of the previous 72 hours so it may not be enough. That still doesn’t work so we will be leaving the thread in their for a few weeks soaked in plusgas and have a go at a later date.

Having temporarily resolved the seized bolt issue, I can now continue with the servicing of this winch.  This is as bad as the first with lots of cleaning required again to get it to a standard where you would be happy to reassemble.

Anyway, at least the other winches which should be uneventful since I have done the hardest ones first…. Or maybe not.  we have eight winches dotted around the cockpit and another at the mast.  Each pair in the cockpit are completely different and the mast is a two speed winch without a self tailor.

To be fair the servicing is not bad, except two of the winches are pretty much jammed due to lack of use and poor previous maintenance.

That is easily resolved and it actually makes it more interesting when you have to work out how the winch is put together each time.  Reassembly is also interesting and I was flummoxed for a few minutes when I put a winch back together and couldn’t drop the bolts into the cogs.  On inspection, the whole was out by 2mm.  Now that just isn’t possible, these things are precision engineered and when not covered in gunk go back together beautifully   I worked out that I had put one of the mechanisms in upside down and the two “same-sized” cogs were actually slightly different sizes.

So I am done on the cockpit winches, lets start on the mast one!  this is interesting and again completely different from any other winch I have done.  For the first time, I take the winch casing off and something drops out – that shouldn’t be possible.  It is a pawl, the part of the mechanism that gives the winch is familiar clicking sound.  That’s not good.  I get the winch assembly off the mast and onto the deck so I can see what needs to be done.

This winch is a two speed winch and it is the slower setting that has both Pawls broken.  I have bought some spares and so can set about cleaning up the winch and getting it back to perfect working order.  Now on my ninth winch, ten if you count one on a friends boat that I helped with, I am confident when putting it back together and it all works first time.

My top tips for winch servicing:

  1. Don’t be scared, things are not going to ping all over the place as soon as you take the case off.
  2. Remove everything slowly and make sure you hold the underneath, sometimes some of the components have others within them.  You don’t want them falling out
  3. Read the service guide, the lewmar one has pictures
  4. I put my finger at the end as I lift the pawl out of place, this means that the spring hits your finger rather than pinging off into the water
  5. A very thin layer of grease but nowhere near the pawls and oil around the pawls.  I had it so that they felt greasy but you couldn’t really see grease on them
  6. Take your time and clean everything really well, it will cost an extra five minutes but if you don’t do it you will know it every time you look at the winch

 

 

Taking a week fixing what broke in a weekend

We had an eventful weekend in the Stour and the broken list was extensive.

  • Initially the large domestic alternator had broken down and I had disconnected this to try and prevent any further damage.
  • The davits had stopped working and this seemed to be electrical in nature too.
  • We still had a problem with water flow to the engine
  • We had a sheered bolt in the impeller

To this list I added a couple of long outstanding jobs:

  • Replace the hydraulic rams for the swim platform and get this working again
  • Fix the mount for the navigation on the rib and make sure it now charges

Firstly the cooling problem.  We knew that this was related to the through hull and so the first technique we tried was to attach the filling end of the rib’s foot pump to the pipe from the through hull.  This would create air pressure that should shoot out whatever was in it like a torpedo.  Or not.  Lots of pressure and difficult (read almost impossible) to increase the pressure further with the foot pump.  So that didn’t work but we know there is something blocking it.  The next theory was to insert the dockside hose down the pipe and blast it out with water.  I do not like the idea of filling up the boat with a hose (water tanks excepted) but I wont be blasting for long.  With Maria holding the hose in place and a cloth over it to avoid any “blow-back”, we test slowly. I imagine Maria wouldn’t be too pleased if she and the engine room wee soaked by an icy blast of water.  One second burst, five second burst, five minute burst while I discuss with Peter, our neighbour, the problem I am trying to solve.  Oh sorry dear, forgot about the hose. Fortunately no drama or screams from the engine room.  Put everything back together and a quick check of the engine – we have full flow! 🙂  Subsequently, I heard of another technique that I also think would work which was to use a plunger from outside the boat, but Maria wasn’t keen for me to go swimming in the locked Marina water.

For the swim platform and impeller bolt, I will need to go to a chandlery to get spares (hydraulic fluid and bolts).  I go to Fox’s chandlery locally but they don’t have the right bolts and they are asking detailed questions about the rams and the pump before agreeing which hydraulic fluid I need.  I phone the UK distributor for the Bennetts rams who explains that any automatic transmission fluid will do so that saved me some money since it doesn’t have to have marine in the labelling.  On my return to the Ipswich marina, I see Lindsay from Seapower and explain my difficulty obtaining the right bolts for the impeller plate and he has a couple of spares “in the van”.  So I am sorted!

The sheered bolt is remarkably loose and I am able to spin this round with my nail to retrieve it.  Spin may be exaggerating a little, I can move it without drawing blood. I had tried to use a tool to help but the lack of visibility meant it was easier to feel your way with your nail. I replace all of the bolts with longer bolts having checked that they will fit correctly and that is another job ticked off.

Onto the hydraulics replacement, carefully lower the tank to a level where it wont try and fill the system when I take the old ones off.  Place a container under the rams to catch any fluid that leaks out.  The swapping over is easy and it is now time to try and bleed the system.  Back in the lazzarette, to find the reservoir lying nicely on its side and the hydraulic fluid coming out of a rip in the lid, thanks, and after I had tried to be so careful.  Refill the system with the new fluid. It is quite a small system and there appear to be no bleed valves so it’s a case of opening and closing the bypass while activating the pump.  It is all good and I am finishing the bleed when the platform starts to come up. And I am holding the down switch!  Our friend Mat, marine engineer on Song of the Whale, is coming for dinner, maybe I can pick his brains.  Mat and I take a look at this and the Davits.  It seems that whichever button you push it comes up, and if you swap the electrical connections over you can get it to open, no matter which button you push.  So a problem with the switching that needs to be solved when Ollie from Seapower comes back to the boat. To be fair this switch was wired when the platform didn’t work so easy not to get it right.

The davits are interesting and we spend time looking in the control box.  There is what appears to be a slow burn fuse that is located on the edge of the box and pokes through the box at the top.  This has the same pins as a car fuse and we swap this for one to test it.  The davits start to work.  Taking apart the black slow burn fuse reveals water is inside it (from all of the rain the previous weekend!).  We clean this all out and replace it.  The davits are now working perfectly. But who puts this outside of the box when there is likely to be water, we cover the top of this in tape to hopefully overcome this problem in the future.

As our final job for the moment, we take a look at the alternator.  alternatorWe had found that a bolt had sheered which held the casing of the alternator together.  This had come out and had significantly damaged the vanes of the fan, which also explained the noise Maria heard.  So we get the alternator off and I will take it to the local specialist to see what can be done.  On investigation the alternator is fried and badly damaged which makes it uneconomical to repair.  A replacement is available and should be with us within 24 hours.

It is interesting though that since removing the alternator, some electrical devices are no longer working, and the engine circuit will not power up.  I had taped off all of the wires for the alternator. We put the negative from the alternator onto an engine bolt and everything starts working again but we are both at a loss to explain why the engine earth is going through the domestic alternator.

The next day I have refitted the alternator and tightened everything up. Just as discretion is the better part of valour, cowardice is the better part of discretion so I want Mat to check my work before I restart the engine.  We are all fine and so decide to test the new setup.  The engine starts well, we have water flow and the charge is also looking good although the batteries are pretty full at this stage anyway. We are working our way through the list well.

The new mount for the rib navigation has arrived which is a straight swap with a little help from Maria to hold the screw driver on one side while I tighten the bolt.  Definitely not a one man job unless you are stretch Armstrong.  When perusing the instructions I discover the original problem.  Apparently the mount comes with an all weather cover for the electrical connections.  That will stop water pooling around them causing corrosion and the mount to fail! RTFM.

Another job ticked off and I’m feeling good – maybe just lift those davits….nothing!  Maybe they are on the engine circuit so I need to power that up.  Nothing! In fact no light on the engine circuit at all. So this appears to be the same problem that I had when I took off the old alternator….but the new alternator is fitted and the negative is connected again.  I speak to Mat quickly to get an opinion and we agree that I need to look into why the domestic and engine circuits are connected.  I have already checked the “parallel” switch, for anyone starting if the engine battery is dead, and this is set correctly.  So it is under the bed in the aft cabin to check out the wiring there.  negative meltdownThere is a problem, it appears the bolt holding the engine earth to the negative bar is loose (right hand side of picture).  This has caused arcing between the cabling and therefore heat build up with some scorching.  In fact one of the negatives has corroded and melted the insulation so much that it has melted through another wires insulation and these are welded together.  That will be what caused our problems and it could even have been what damaged our alternator.  In some respects we were probably lucky the alternator went rather than continuing to build the heat up and potentially start a fire under the bed.  This doesn’t explain why the old alternator used to provide the earth to the engine and the new alternator doesn’t, despite being identical.  The current view is that this was as a result of the damage to the alternator which provided that earthing thereby by-passing the corroded engine earth.  But I will update with more information as it is available.

In the interim we have put a bypass in place for the earth but the engine and alternators will not be used until the above is fixed.

All in all, not a bad week, since we fixed a lot of issues and uncovered a pretty major new one. At least we found them in Ipswich rather than in the middle of nowhere and know how to deal with them in the future – all part of the education!
