Wyatt says
"One thing that all these Infinity wings have in common is they all have the downforce in the wingtips that kicks in at higher speeds. They're all really self-regulating wings that stop you from over lifting at higher speeds. On all these wings in the Infinity line, you have a lot of lift coming from the center of the wing at slow speeds. Then as you move to a higher speed, this sort of downforce in the wingtips, very similar to the twist-off in your windsurf sails, causes it to pull down a little bit at higher speeds. So instead of having to get further and further forward on the board, the faster you go, which is uncomfortable, you're actually able to get more under both feet at medium speeds and then get back onto your back foot at really high speeds as it wants to pull down just slightly and really drive it faster".

I've actually measured a 2 degree downward twist in wing from the root to the tip. Is this what he is talking about? And I do understand that at higher speeds, you do lower the angle of attack because you don't need a ever increasing abouts of lift. And it's probably nice that wing would stall first at root rather than at one of the tips.

My experience is limited. Are other brands doing the same thing? Does this feature delay the wing breaching the surface? Is Wyatt's less downforce in the wingtips a description of less lift in the wingtips at the lower angles of attack associated with higher speeds and wing twist?

Fantastic test in super light wind conditions of the 2020 slingshot infinity 99 wing this week, footage was 2 evenings back to back. Its a monster at 2371 cm2 surface area.

I was short on time, and was using the 42 rear wing in position B on the fuselage, so still more tweaking to be done with using the 48 rear wing in position C for maximum light wind lift.

To foil in 5-10 mph* with a 125 liter board, 5.8 RAF sail, and I weigh 205 lbs is next level.

*does require full body pumping technique and gust timing, its not a static start
