Yes it sailed both directions- the seat stayed on one sideIf it doesn't go both directions it's not a proa.
You had to build a full size prototype to figure that out? What did you expect would happen when the sail wasn't holding up your weight anymore? Did you add the ama?
canoes (with sliding seats) that are 30” wide areNotoriously tippy Anyway. I can sail a narrow sailing canoe- I thought I’d give this a try
tried the ama, but it was not feasible given the internal structure and the seat needed to swivel to move the foil and weight longitudinally to be part of the steering system, so linkage would have been involved- the whole thing was supposed to be a sit down pros windsurfer- very minimalistic- ha!
