Yes it does. The WSSRC have set lower depth limits to prevent people taking advantage of this. The kite-boarders were probably best able to take advantage of shallow water prior to this.

@@paularsen1 you might want to take a look at a NASA white paper by AL Bowers on the Prandtl wing. Al did a bunch of work on drag reduction via twist.

It's kind of a technicality. Cavitation is usually associated with fully submerged foils. Ventilation happens on foils near the surface or more commonly on surface piercing foils, when air is sucked down to the low pressure side of foils. The dynamic pressure of the liquid drops low enough below atmospheric pressure,sucking air and causing an air cavity. Regular Cavitation happens when the dynamic pressure on the foil drops below the vapour of the fluid which essentially boils a forms a vapour cavity.

So can you do better?

Do you have an address for me from Ben Holder?

Hahaha hahaahahahhahhaaq

Bahahaha

Lotta good that musta been. ROFLMFAO ❤

I laughed... lol. To relax, uh huh. But you're probably right.

I think the foil went from being side ventilated... and thus effectively skidding/planing solely on the high pressure surface to being "wetted" on both surfaces and base ventilated (as designed). This latter mode generates lift on both surfaces and thus "skids" less. The foil bit in. You can actually see the spray pattern change in the overhead view. We included all the interesting bits in this very specific edit... as I use it for talks to highlight the key points:) I hadn't seen or felt the boat do this before. I had to make a large correction to the wheel when it happened (Highly geared steering).

Cut my teeth on Hobies.... so I'm hearing you;)
