been thinking about this while cleaning fruit to make preserves, a good
boring opportunity to think.

If water gets into a carboard boat it's mush. I'd tape the plastic right
over the top to keep out spray. Probably should be supported by some
"deck beam" framing which would also act as thwarts holding sides apart.

If there were time it would be interesting to design a carboard surfboard
with a small cockpit (like a board sailer) to kneel and paddle in. Open
top. Interior cross framing like PC's honeycomb framing. Entire structure,
including interior of cockpit, wrapped in plastic to keep it dry.

Maybe the race organizer will post photos on a website showing all boats.
