Thought I'd start with a stunningly basic question, what make is it? Then I noticed it's the same (I think) as the forum's banner photo. So hopefully not too hard to identify.
Hi. That isn't a Ribcraft. Can you post some more photos? Tube appears to have quite a taper on the bow - not sure if Olmec made any boats this size but has that sort of look about it. More photos should reveal the answer!
