Micro camp cruiser

This is a concept boat that I've been thinking about for a while.  A 15 foot camp cruiser with a
small cabin to sleep one and gear.  It would have unstayed mast(s) for easy transport or clearance under bridges......
The cockpit is large enough for sleeping too.  Oars would be the other source of propulsion.

It would be a small cabin, even just for one, but not so small that 2 wouldn't be able to cram in if needed.  I would like it to be under 300 pounds in weight.
