In hind sight, wouldn't it have been much safer, and perhaps even minimized some of the breakage, if they had simply allowed foiling and allowed some type of adjustable elevator/flap on the foils to control their ride height, like the Moths and most other foiling boats are using?

Watching these guys learning to foil, with no control, is like watching the Wright Brothers learning to fly! And they crashed, a lot, until they figured out their elevator control system.

So now that we KNOW HOW to fly, why not just let them FLY!? With some CONTROL!
