Yep. A properly done repair is NOT like a stick with duct tape. It's stronger than original. Is it cost effective? I have no clue but I doubt it.
A proper repair grinds out the old broken fiberglass every how far one needs to go to get to solid glass. The glass is scarffed (tapered) from full thickness down to nothing. Done correctly, new fiberglass bonds with the old and becomes part of it. Not a patch in any manner. Just like a proper weld is stronger than the surrounding metal.Regardless, there is no way it is cost effective on a boat that old that is so readily available at reasonable prices. Even if one is a fiberglass expert the time and materials would be very expensive.
Nice Boat 8) Seeing as how the bow rail isn't complete, that's a perfect excuse to take it off Good Luck, I hope it's what you're looking for
