Boat repair

I have a pelican bass boat,it's 11 ft by 3 1/2-4ft.I have a split on the bottom of boat,in the left rear right on the edge of the bottom.I was wondering if anyone had any suggestions on how to fix the problem,none of thed epoxy i have used worked,i don't know if i need some sort of patch or what.any info would be helpful.
Thanks,Petralunker

You might wanna look into a fiberglass repair. Fiberglass resin with with a fiberglass cloth or matting might be a good start.

how bad is the hole? do you have any pics?
