I like the design - simple and efficient with plenty of prop details to make it look like it could actually float down an river.

My question is: where does the party sleep? Is this more like a barge where there's no 'below deck' and it's basically just a glorified raft or is it an actual boat?

Either way I would suggest that your party may not want to sleep out on the raft without cover. I'm not sure how you'd handle that though - perhaps some kind of simple cover in the back?

Looks great!
