Happy Jax 3 Posted November 24, 2007 Share Posted November 24, 2007 We have just had out boat lifted out for the winter season, this is the first lift since it was purchased earlier this year. It is an ex Castle Craft hire boat (GRP) approx 9 years old. On washing down the hull, I have noticed that it appears to have std blue antifoul around the water line. However, underneath it has a black substance, almost tar like, but dry to the touch. Have not seen this before. Is this normal practice by the boat yards? If so where can it be purchased? I assume it must be cheaper than normal fresh water antifouls. I also have a concern regarding being environmentally friendly, If it is not the case can I cover it with a fresh water antifoul? Any advice would be very much appreciated. Quote Link to comment Share on other sites More sharing options...
