You cannot go wrong with Pettit Trinidad HD, a hard multi-season bottom paint. However, I do not
recall if you presently have a hard or ablative bottom paint on
hull. If hard antifouling paint is currently on
boat you can apply Trinidad, but not if
current antifouling paint is ablative. If ablative is presently on
boat, you would want to sand extensively to remove most of the existing paint prior to applying a hard antifouling paint. Yes, Pettit Trinidad is definitely expensive, but worth the
price. If you are going to pay to have the
work done or, even more importantly, if you are going to do the work yourself, it is worth paying for a quality paint.
