I have coppercoat on my 45 Classic and on my previous Beneteau. I like the fact that you do it once and it lasts 10 years. That said it did need abraiding once on the Beneteau to bring more copper to the surface. Long term its a cheap option. If you lift out they put my boat in a nicer part of the boat yard because the copper isnt as toxic as the other anti fouls. If you sell your boat having copper coat is a plus point.
