How about optimal board volume to flatwater foil SUP start? Or optimal board volume /rider weight? Liter/kG? Or kg of rider weight per liter of board volume? I’m thinking of buying a Gong foil sup setup for flatwater foiling this fall. What board size should I get if my goal is to learn to flatwater...

Competition will help. As soon as enough people are able to flatwater start a SUP foil, then supfoils can start competing in sup races. Standard distances are 200m, 4km, 8km, and 16km. Just as relaunchability is the limiting factor for some kite uses, flatwater start-ability should be the goal of fo...

Optimal front wing area? Or maybe optimal ratio of wing size to rider weight?

Gong has a front wing up to 2400 cm^2.

At some point, drag will overtake lift. Are we there yet?

Good to see people experimenting w new foil setups.

Perfect middle ground between lei/double skin foil kite/ single skin?

Is water relaunch as good as the hyperlink and soul?

The fastest motorboats are non-hydrofoil. They skim the surface like a kiting speed board. Even sail rocket was not fully foiling. 1-2 of its points of contact were skimming, with no foil at all. It only used a foil for lateral grip on the water, not lift. And its lateral grip foil was super-cavitat...

Slingshot sells a different stabilizer (48cm wide, instead of 42cm) to go with the Infinity 84 wing. If you look at the full package w infinity 84, it has the larger stabilizer, and it is mounted underneath the fuselage instead of on top. AND, the mast is shifted backwards on the fuselage (windsurfe...

Plenty of marketing hype...

"Internal wing profile"?

If trying to compete for lightest wind LEI kite, they should have posted weights for each size...

It is a lot smaller, so not much influence. And the back wing reduces overall lift, as it pulls a bit down, negative lift usually. 8) Peter Sometimes it is not a lot smaller. When I use the speed wing in the front, the back wing looks about 2/3 the size of the front wing. And regarding the negative...

Duck-tacking vs no foot switch (heelside/toeside alternating)

Yes, probably easiest to train for the challenge in open water.

The real goal is to be able to maneuver in tight spaces as well as a sailboat, opening up new navigation options.
