I am retrofitting a drift boat. I already built in 2 watertight storage units but would like to tuck a thwart under the rowers seat and lash it in. Probably 12-14f raft size. I am trying to build up enough floatation that the boat will not sink if swamped.
I built a bunch of cat frames over the years and have leftover Ts, oar, etc... consider trade or cash.
When I bought a new avon back in the early 90s I stuffed the thwarts somewhere, and never used them, but they seem to have walked away over the years.
