GL wing info
« on: August 08, 2020, 03:42:01 PM »
Not sure if this has been discussed already. Where can I find the surface area info on these wings? Certainly on on thier website!  >:(

Don't remember exactly where I found someone posting these, but they at least seem pretty close in comparison to similar sized/shaped wings from other manufacturers.
Me: 6'1"/185...6'0" Kings Foil Board...6'0" Chelu Foil Board...9'6" Bob Pearson "Laird Noserider"...9'6" Costa Azul Wide Body...14' Lahui Kai "Manta"...8'0" WaveStorm for when proning urges still hit, and 7'3" Chuck Glynn foil board backup.

And if anyone is wondering the Australian Distributor posted the upcoming NL dimensions for comparison:

NL130 L 76cm C 18.5 weight 711g  
NL160 L 91cm C 18.5 weight 838g  
NL190 L 99cm C 18.5 weight 876g  
NL220 L 99cm C 21.5 weight 976g

Not that I have seen but this comparison between the NL and GL was really good if this Instagram Story is still around... those NL wings are thin!

the NL wings are SUPER fast!...the engineering team worked for over a year trying to reduce the quadratic drag on the wings while still providing enough lift...they got it!.....intuitively you know it's correct...a skinny knife blade cross section  on the leading edge of wing slices through the water easier than a thick fat leading edge...fewer  particles of water needed to push out of the way

BUT

this means like Sano said the  wing is sharp!...very similarto kitefoil wings....these are definitely not beginner wings...very fast, very maneuverable, like to be ridden very aggressively...if you're at that skill level...you'll say MAN! this thing is FUN!...

Are they like Moses/Slingshot leading edges, where they look “odd”, because the front is nearly as sharp as the trailing edge?

Not talking about thickness, obviously the Moses/Slingshot are thick wings, but they are an odd ball looking wing compared to others, because the leading edges are pointy/sharp.

Always thought the Slingshot/Moses wings behaved better than a lot of foils for “windsports”. Just figured there was something about the airfoil sections that suited windsurf and kite foiling really well.

The conventional foil profiles for hydrofoils have never seemed to make a huge amount of sense to me since the riders control lift through varying the AOA. The kind of foil profile used in very high-speed aircraft would seem to be more reasonable, especially given the difference in density between air and water, with 1000 times higher density a wing operating at low speed in water should probably look like one operating at high speed in air. That's more like Moses foil design. The Clark-Y style foil section generates lift even when the AOA is 0 and that lift increases as the square of the velocity. That would seem to make it hard to control at higher speeds. That's especially true when the stabilizer has a few degrees of incidence cranked in that is constantly trying to increase the AOA of the front wing.

It's surprising that these things work at all, never mind that they work for a large variation in rider weight and speed.
Foote 10'4X34", SIC 17.5 V1 hollow and an EPS one in Hood River. Foote 9'0" x 31", L41 8'8", 18' Speedboard, etc. etc.
