Wing Specific Hydrofoils
« on: December 09, 2019, 03:57:55 AM »
I was down at Windance yesterday to pick up up an (air) wing that had arrived and they let me know that Moses has designed a Hydrofoil wing for Wingsurfing that is coming available.  Pretty sure this is the one https://store.moseshydrofoil.com/products/wing-1020-surfwing .  That set me to wondering.  What would a wing specific hydrofoil look like?  What is missing in the currently available foils? 

Surface   2100 cm2
Root Chord   246 mm
Span   1100 mm
Aspect Ratio   5.7

My guess would be a good marketing spiel to part you from your money? Works every time on me ;D

Looks like a very nice wing, highish but not ridiculous AR. Useful size. My gut is telling me their wing to fuse connection is lacking in contact area for larger wings, arguably worse than the Go Foil / Gong square taper (which is still weak compared to Axis and some others).

I think we already have wing specific foils from Axis and GoFoil.  Moses/Slingshot didnít have anything modern and appropriate until this one.

Yup.  3.1 inches longer than the Axis 1020 with the same chord and just a little more area.  I wonder about the thickness.  There is a lot of room between the 900, 1000 mode and the 820, 920, 1020 mode.

Its all about speed profile for the wing.

Ocean waves move at 8 to 12 mph, most normal sized waves.  The key to FOIL surfing was getting wings to work at these slower speeds.

I recall from my windsurfing days that a windsurfer started to plane at 17 mph.  Much faster than a typical ride on a wave.  These wingding specific foils will probably be optimal in the 12 to 20 mph range.  Meaning slightly thinner and faster than a good wing for surfing in typical crappy waves.

Beasho - interesting point - for me, one of the main attractions of winging is it's compatability with wave riding, whether downwinding, or traditional surf riding. Having a foil optimised for faster than wave speed doesn't do it for me.

Also, faster foils might require an adjustment in wing design to cope (EDIT eg to maintain handling and efficient use) with the higher average apparent wind speeds.  However, who knows whether wing racing is going to become a 'thing' which will need designs in a different space to what has come thus far...

I think you are right.  We have great instant lift and cruise wings like the Axis 1020 and 920 which are still really thick but then there is a pretty radical change to the (notably faster) high aspect wings like the 1000 and 900 which are quite thin.  It leaves a lot of middle ground.  A thinned out version of the 920 for instance would be a very interesting wing.

The only thing that I could see being a benefit is a foil that rides waves as good as they do now and have better up wind speed. I'm dropping to some smaller boards soon so hopefully that'll speed things up a bit for me. I feel like I'm the freight truck on the water as the kite foilers are like cars passing me by. I wouldn't want to give up surf ability for speed since riding waves and swell is where it's at for me.

Exactly the challenge.  And this is the reason the kite foils never worked in the surf.  They were designed to go 30 mph+++.

Kite foils have been around more than a decade but it took Alex Aguerra to slow everything down and re-invent the sport.  Now the wing ding has us wanting to go faster again.

I notice if I'm on the Axis 1020, I get more pressure in the handles due to its speed than I do with the 1000 which is way faster. I rode the Neil Pryde large yesterday and it was a bit of an in between of the two Axis foils in regards to getting on foil and speed of riding and hand pressure but, the pump in the ocean swell wasn't as good as ether of the Axis foils. I'm still in the thinking of people are going to have to buy what works for their ability, weight and conditions. Marketing sucks since all the companies say the same thing about their products.

Amen! When Laitham (GoFoil team rider) tried my wing ding, he said wow, more fun than kiting. Heís a getting full quiver of GoFoil branded WASP wings in all the new sizes.

Fingers crossed the new Axis 880 Gul wing lets us rip harder surfing and still has good pump for the wing ding.

Listen to todays Progression Project Podcast. They talk about a downwind SUP session where 3 guys swapped between the GoFoil GL wing, the Takuma LOL, and an Axis protoype that looked like the 900.

The Takuma is the low aspect wing in the bunch and youíd guess the slowest, but was the same speed as the GL GoFoil. Mind blowing to them all.

The Axis prototype wing was the slowest, yet it looks the fastest on the beach.

Go figure!  We know nothing  ;D
