Squidd,
Ditto what jfdub said.
If you want to be in the water this season, forget you saw what you saw, mix up some slightly thickened
epoxy, slather it on the exposed mat, roll it out, mix up some fairing compound, slather it on, sand and shape it, cover it with some barrier coat, bottom
paint and go. In the fall, soda blast it and spend the winter cleaning it up.
