Ok, let me clarify that a bit - I am looking for a design that
collapses smaller than a "cartopper" possibly could - thus, I'm not
interested in designs with rigid/semi-rigid panels. There are kayaks
that collapse down to a backpack size, and that's what I'm after,
except I want a rowboat instead of kayak or canoe.

Regards,

Michael

Has anyone ever done/tried to do (home made or commercial) a
collapsible rowboat using a plastic (or other) covering on an aluminum
tube frame?
