I have a canvas cover for my boat (13" BW) and it has a rip where the pole is placed in the center and one near the front where it clips to the trailer. Has anyone tried to repair torn areas? These are like 12" rips and in areas with stress. The other option is to fix it and I wondered if anyone has a good place in the Solomons Island, MD (that is reasonable). Just curious if anyone has any thoughts - or is it time to get a new cover? Thanks.
