In 2010, we bought our Dufour 455 and researched the benefits of coppercoat compared to antifoul. Firstly, antifoul needs to be redone each year and this is a messy job. In comparison, coppercoat has been successful for many years on different boats and needs a lot less work each year. We were very happy with the results on the DuFour in the River Orwell and based inside the lock at Ipswich. The boat, after a spray down, was always clean and whenever we had some growth on the hull when in the water, a quick blast down the river and out to sea was enough to clean her up again.
So one of the first jobs we did once we bought the Moody 54, was to shot blast the hull to remove the old antifoul and then apply the coats of coppercoat. With our long term travel plans, we thought about whether we would want to haul out and antifoul all the time and in the theory the annual maintenance on copper coat is a lot less than antifoul.
With the coppercoat, we can lift the boat, rekeying the coppercoat and then put her back in immediately. This should keep the hull clean and make sure that she still goes through the water fast :). It is expensive to apply and the key is to make sure that good weather is expected. Putting on coppercoat in rain or cold conditions seems to be when there are significant issues. We chose a favourable weather window and we have been very pleased with the results with Mariadz being one of the cleanest boats in Ipswich when she comes out of the water and is jet washed down.
