[quote=charlescarlis]Looks like point/pressure cracks, like from weight from above while the boat was on the trailer. If you can't get to it from the inside (access port), then you've got careful sanding back to bare glass for the whole dimension of the crack. There may be more crack under the gel coat that you cannot see, but probably not much. Easy to fix - harder to make it look 100% again. Best to have glass on both sides of the crack...but not likely to be easy to do.
Good luck.[/quote]
