If you think there could be a local weakness in the hull, add a doubler patch on the inside of the hull too. Use glass cloth and West epoxy, the patch should be similar thickness to the hull and extend well past the crack. Be sure to get the temperatures right (read the instructions).

Grind the crack to a "v" angle and sand. Only use fiberglass epoxy resins/materials below the water line.Mix resin and the filler(silica) then glass over. Use resin and a fairing filler to smooth out.Best bet is to use WestSystem.Pick up the catalog for the right type of resin/hardener/fillers.Temp sensitive and a long cure8-12hrs.
