If I would have imagined 20 years ago what the kite foilers can do nowadays... I'm guessing some combination of kites, foils, sensors and computers will have sailing "vessels" doing some equally astonishing things 20 years from now. The ultims are closer to planes than boats. If there's no giant pole sticking up from the middle of the boat the chance of a multi flipping is cut waaaaay down. Of course, skipping across big waves at 50 mph will pose another set of problems and then there's the issue of what happens when (not if) the foil hits something or the kite strings slice something or somebody in half. By then they'll probably use some kind of quantum transport system to defy time and space anyway. The RdR will start tomorrow and they'll finish yesterday.
Yves Parlier is recycling his 16yo cat along those lines (pardon the pun).
