I have a 45 foot sloop, two years old. Can anyone please tell me what a fair price is to have a boat yard redo the bottom with a good quality ablative paint. I purchased the boat new with an ablative paint on it already - quality unknown. I have no prior experience with boat yards and feel obviously helpless with every conversation. I learned the cost of the paint is about $200 +/- per gallon. But I can't find reliable information on what a yard would charge a knowledgeable owner. Thanks for any help offered.
