Save yourself time, money and problems later on by checking the whole hull when you hook your boat out of the water for blacking


They might be an obvious item to check, but watch out for new ones being fitted and old, worn out ones being left on. The hull can rust behind them. Much better for old ones to be removed completely and then the hull to be blacked where they were.
