Re: Gelcoat cracks in Sabre
I had something similar when I got my boat but it was concentrated at the points that the headsail cars went. The machine screws that held it in place were only backed up with washers, which is not nearly enough.
I got a strip if about 1/8" SS an inch wide and cutting it in several pieces to allow for the bend, installed it as backing plates for the whole length of the track. We held the plate in position and used the drill to mark a spot then drilled through it.
