Check with local marinas, boat yards...
The need for bottom paint is depedant on the local conditions where your boat is moored or slipped. In NH, I've kept my boat in fresh water that was not too weedy without any bottom paint for about 8 seasons (5 mos per season. At haulout, I'd pressure wash all the growth off and sometimes in the spring would wax the hull before launch. Other areas of the some lake were shallow and weedy and boats kept there needed bottom paint. VC-17 was popular, and didn't need to be done every year.Regards,Tom
