I agree with the last response in that you may not get what you expect for the money your gonna lay down. Boat yards are notorious for half arseing the work you are paying for. After all it cuts into their margin. A job of that magnitude when you want a large enough quantity of material to be applied to the hull to satisfy your justification scale is the kind of job that you either have to do it yourself or watch the yard extremely closely. My local yard is famous for putting on a single coat of bottom paint when you ask for 2 or 3 but for some reason they don't forget to charge you for the 2 or 3.
