Cool! I have the 1 and 2 person air trib. They are solid boats. Never had any trouble with the valves (but one of the floor overpressure valves goes off a little early sometimes). Easy to patch too, if a rodent decides to chew through it. So far they have lasted about 7 years maybe? Mostly on the Salmon river in Idaho, and a little on the Payette. Yeah, slow! Have fun!
