Have you ever tried to sail a International Canoe w/ a slider???? or a Chesapeake Log Canoe w/ planks???? or a TheMightyHobie18 MAGNUM??? I've done all three ... well I've attempted the first two with various degrees of success and the H18Mag I do all the time sometimes just on the wing and sometimes trapped off of the wing.
With the IC I spent most of my time swimming ... tippy boat, and I could never get the hang of it.
The Chesapeake Log Canoe ... ALOT of work moving those planks through from side to side. Then out on the plank ... in on the plank ...out ... in ...out/in ... then you have a hole in your sailing shorts !!!! Or if someone's timing is just a little off ... it's swimming time!!!
Trappin out from a H21SE or a H18Mag is a HOOT ... you are high above the water .... and when you stuff it you go flying so farrrrrrr....... Onetime while double trapped off the wings a micro burst hit us, immediately driving the bows under and off we went ... Tarzan and his apprentice ... we snapped both bungies ... and swung out and up until I was looking back at the boat, standing on it's bows as we dragged it forward through the water at the end of the trap wires with our weight/momentem. I never have fallen so far before I hit the water ... we must have been +25' in the air at the top of the arc.
Then of course there is also "The Thomas Crown Affair" w/ the "Ladder Rack" salvaged from one of the Worrell N6.0's. Rick Bliss?? took that leap I believe ....
So having done three of the four ... I recommend a "GOOD" Crotchless Harness ..... I got a Murrays Crotchless when they first came out(1988-89)... used them up eventually (I had two that I had new "seats" sewn in by a sailmaker to extend their lives), good harness .... got a "Musto 6-8 years ago, EXCELLENT ... tried my friend's "Black Magic" recently, even BETTER .... So there are some excellent harnesses out there, the secret is just make sure you have a good spreader bar.
On that Video ... do you think that masthead US flag had something to do w/ the flip???? Once you fly a hull too high the wing drags in the water ... the boat stops ... and gravity takes over .... SPLASH. Thats why you never see TheMightyHobie18 Magnums in hull flying contests ... before you get to the neutral balance point you drag the leeward wing .... and you're done ....
