IMHO they are worth saving. They tried to make a really good boat, but just failed in a couple ways, like using metal staples to attach the deck to the stringers. What they did by doing that is they allowed water to enter the stringers once that metal rusted. Look at my videos, you'll see how bad the stringers were. And also the foam used between all the stringers just soaked up the water, really bad. On top that, where they made holes to spray in that foam was not sealed, so there was a natural entry point for the water. A couple easy changes woulda made it an absolutely fantastic boat. But the good news is, the fiberglass is thick, and it seems like a really tough boat overall. I'll see how it pushes over water later once I git'r done! lol
Best of luck to ya.
