I have had some part sheets of plywood and epoxy hanging around for a while and have just enough to add a tank with hatch at the bow and then with what remains something in the stern.
Then going to add a down/reaching sail. No board just a paddle and posible a skeg. Still thinking about the sail, keep going between:
- simple battened triangle
- stand lug with boom
- standing lug no boom
- balanced lug
Anyway simplicity the goal so letting it percolate
