Rear steering is NOT stable. There are several videos out there of people being thrown off rear steerers.
interesting machine. 5 stays when we build with none!.
the biggest problem I see is the times when the slap down happens so quick you dont even get time to react.
on this yacht you would shoot out the back , presumably missing the stays. same thought would apply to a long 2 wheeler. at least on water you can watch the waves and see the gust coming
