[quote=Headhunter]That's a significant hit. You'll want to pop the deck lid and inspect any bulkheads nearby and re-glass them as needed. I would grind the exterior and interior of the damage until you get unmolested glass. Don't worry about replacing the foam core, just glass the whole thing with something strong like 1708 and your glue of choice, be it epoxy, vinylester or polyester resin.
The pic appears to be red gel, you can try to color match with gelcoat pigments but it'll never be 100%.[/quote]
