I've been given this old raft, at least 10 years old, it's a 14' Campways bucket boat, made of hypalon. Still holds air quite well, lots of life left in it. The floor, however, is just riddled with holes and damage. There are numerous spots where a crease resulted in cracked rubber (or whatever that stuff is) andd visible threads, lots of places where the rubber coating has come off leaving nickel-sized holes with nothing but threadd underneath. At least a dozen existing patches, and the tape over the seams is just plain wearing out. Here's a pic:
I've circled existing patches (most but not all) in yellow, and most (butnot all) of the spots needing patched in red. And this is only half the bottom, the other half is just as bad. There are lots of similar spots on the inside of the bottom.
Should I be doing something other than patching here? This seems likes an awful lot of patches, and I"m wondering if there's some other approach I should be taking? I'm not interested in replacing the whole floor, so any other options?
