Self righting and unsinkable?
Don’tcha wish the bigger stuff was like that? I saw an auction for an ex Coast Guard training vessel thats designed to roll completely and come upright, I saw a video of one used I think just off the coast in Oregon, massive breakers there. They had the engine mounted very securely and able to run upside down, must have been a Detroit.
Things get easier at smaller sizes. It’s the same reason why the tiny quad rotor R/C helicopters are so agile. Less inertia, smaller forces. A hurricane won’t blow out the sails on this thing, just tumble it around for a while.
