Here's a few foil videos from four years ago.
Link doesn't seem to work but search Surffoils at Vimeo.
There's a foil shaped like a bullet
another like an inverted T
and another Aluminium one with Three foils at different heights. They all have an aspect ratio of less than 1, that is they are longer than wider.
They're scientific videos not commercial ones so they're not meant to entertain you.
With these design foils you can launch out of the lip and pull into barrels.
This is what Sup foiling is all about....Fun waves, warm water, no straps, good board & foil (Jimmy Lewis Hover Craft with GoFoil Kai) Konrad Bright enjoying the glide...Hawaii
"synchronized foiling" :-)

Brett Lickle, on a prototype 7'2"x30" JL board with a "step tail" to try to avoid touching the water with the tail while pumping.
Note the use of a coiled waist leash, straps, and a centered position (feet on each side of the handle).

"The function of this step tail is to allow him to pump his board up onto the foil with considerable less speed than what it takes to do so on his current board."
Interested to know does the stick on mount work as good as the boxes , and does the mast still have adjustment on this mount . Haven't seen it , am a newbie also wanting to get into it . Thanks Roachy
Ever wanted to know what is happening when you breech?
Here's two breeches I captured on my GoPro slowed down to 10% from 120 FPS (i.e. very slow). The first one plays after in real-time the slow-mo so you can see just how quick it actually happens. The Naish Foil recovers very quickly and starts lifting again ASAP.
As soon as you loose lamination, you loose lift = going down. Pretty cool to watch the foil re-gain lamination as the speed decreases. I am sure Colas will engineer this for us
very interesting, shows how the foils are only working at very shallow angles of attack, defiantly something to be learned from this.
Yes, quite interesting, thanks JB!
It reminds me of what happened with the dreaded ventilation of the fin that plagued sailboards, ending in out of control spinouts. At the time we tried to prevent the ventilation to progress along the fin length, but clearly we do not want this on foils, since if the ventilation was kept in place, the thing would go into a "death spiral" with lift only on one side. In your vids we see how the foils looses lift everywhere so you can get down in a straight line.
I've been working on my reo's lately and today got some nice ones. The gopro isn't really the best for foiling, but you get the idea.
I actually broke my GoPro mount 4 waves in, so most of the footage is mouth cam.
I am also for using always a leash, but in his case, I guess the thing has nearly no volume and act as a board anchor when not foiling...
There is some amazing footage being dropped daily on Facebook and instagram down wind foiling lately.
Dave Kalama is killing it. Flying down wind.
Kai and the Maui boys have to have some of the highest levels of fitness on the planet that amount of work they are doing prone down wind foiling is freakish.
