The hydrofoil had a smoother ride, but the upfront cost seems to be $400k. Reviews also seem to indicate that it is computer limited to 31 mph. That is probably for safety reasons and I suspect on the water that feels plenty fast.
I think these would play well in the SF bay. Wouldn’t be bad to skip the traffic on 101. Google had a ferry from SF to Mountain View for a while. It was epic. They canceled it due to the program leaking and some idiot protesters complaining that tech workers shouldn’t exist or something like that.
