I've had my hobie cat 16 for a long time and I never got around to maintaining the hull bottoms. Now after beaching it all the time and whatnot, they have worn down and one of them is leaking. I've read alot about different methods of repairing the hull bottoms but I'm not sure which one applies to my situation. I'm including a picture of one of the leaking spots on the hull that leaks with this post, then the next will be the other leaking spot, and the third will be a picture of the other hull, which is not leaking but still worn down.
