Sorry for the delay, but I was traveling these last days.
It is true that it is very hard to find objective
reviews on Finsulate. And those I know who chose for it in the past, are not 100% happy with it. But I think that you have to split the problems in two groups:
I know about problems earlier with the adhesion. Therefore, I decided to keep primer and Finsulate together in one
contract, resisting the possibility to put the epoxy-primer myself. Avoiding this kind of problem.
Finsulate, or Renolite, certainly are not the magic solution (than everybody would go for it already), so for me it’s also a question of having correct expectations. Apparently (at least in the tropics) it still needs regular
cleaning, and it works better when under way. Like some alternative antifouling, staying lots of time in a marina seems not favorable.
And there are as many opinions on antifouling as there are brands.
That said, I am not considering myself an expert, but we take the change indeed. One owner reported me that every place they visited, seemed to have a different species attaching itself on their Finsulate
hull. But
cleaning them off appeared not very difficult. So I expect that I will have to dive from time to time under the
boat to clean it, still avoiding regular haul outs or putting new antifouling every year. And I will find consolation in the idea of not leaving toxics in the places we like to sail.
Good luck with your choice.
