I got a PB today, 12.5knots 2 second. Pretty chuffed

Some folks in SF say they hit 35 knots. Personally I've only hit 25mph on both an ART999 86cm carbon mast, and on a mikes lab 110cm mast, both overpowered (~20knots of wind) on a 6m and flattish water. The Art was stable and didn't need any more front foot pressure over 20mph. I had lots of pull from the wing and I feel it could go faster with more wind.

ML had a lot more runway on the top end and I haven't fully opened it up yet, but I have to adjust the positioning of it since I ran out of front foot pressure to keep it down. These foils regularly go 40mph.I hope to do over 30 knots this spring on the ML.

Great video of speed and racing talk^

hello, what model of ML are you using?

I'm starting with an ML 1100 and it feels wonderful but at the moment I am not past 20 knots, I had to delay the foil on the board due to excessive pressure on the front foot.

I am a 70kg rider and that can penalize me, I notice a lot of lift and glide but to go really fast I may need the ML 800

On SAB W671 (570 cm2) / S399 and Naish matador 5m wing and 60L board, I maxed at a bit over 22 knots
It was semi-glassy water, mostly offshore wind, just almost perfect conditions for speed.
I think with a bit more speed-oriented wind wing and a sinker board one can push it over 25 knots but not by much.
All claims of anything over 25 knots with similar setup is very questionable imho.
It really depends on how you measure the speed (gps device you're using, frequency of measurements and a whole lot more of technicalities).
Once I came home with 27 knots max speed (garmin Edge 830 GPS mounted in a waterproof pouch on my belt) but couldn't believe (it was too much chop to set any speed records), later on realized that the max speed came from a big wipeout, when I got thrown out of the board the gps happened to register that speed.

Very interesting, thanks for the info.

20.08 knots is my best 2 sec peak on wing kit so far.

The gear I use is:
5.2m Reedin SuperWing
112L Reedin FeatherWing board
1280cm? Reedin FlightAttendant foil

I did that speed in about 15 knots of wind ish.

I have no idea how fast the Reedin gear can go. I don't think the foils are specifically designed for speed but I still feel like it could have gone quite a bit faster. I just don't have the control yet.

Plenty of decent speeds, usually a very fun game.

I have a custom 5m wing I built myself and have had decent time with Axis foils.
31 knots on - HPS700, 420, 86 mast. I've been riding the ART799 recently a fair bit, had a decent session a few weeks ago but I'm unsure of speeds, I had my band snap on my watch and lost my GPS data for the session. I was only on a 4m wing in 30knots, but decent sea state to scream down at TWA 130. Didn't feel much more than 25-28 knots, but the ART feels more locked in at speed. When really ripping with the 700, I feel very limited control, and the foil is producing maximum lift.

I'm looking to build a custom ART799 scaled down to 530cm2 for actual speeds.

21 knots is my peak speed to date. That was on a HA925 and chopped V tail riding with a +1 shim (zero). Aside from that one time, I consistently can hit around 19-20 knots on HA725 and chopped v with no shim (-1).

I just picked up the HA195 so I'm curious how that will impact things.

These speeds are in surf and chop conditions.

I saw Foiltycoon posted on instagram 26.3 knots on art999 with 400 progressive rear. I have not heard good things about these new progressive rear wings, but would like to try them.

That is crazy fast compared to where I top out on pretty much that setup (ART999 with 400P, Ultrashort fuse, 19mm 820 mast).

When I ride the 999 it will hit 30 kph with zero effort, but then it starts to get lifty. When I'm nudging 35 kph, I feel like I'm on the edge of blowing out of the water. Must take some serious skill to hang on to a 999 at almost 50 kph.

p.s. If you are after top speed, you'll probably want the 380 rather than the 400p, but the progressive rears are a great match for the ART999.

I also freaked out with Foiltycoon mark on art999... Are progressive rears more difficult or unstable to ride?

If others are noticing excessive lift at 30kph, you might find he's used an negative shim in the tail or mast plate. The only way to gain control when maxing front foil is to reduce tail as much as possible.
That being said, with a negative shim, and those speeds, the 999 might make a very good wing for its massive range

Benchmarking speeds can be found at gps-foilsurfing.com
Most of the Garmin gadgets are not very good at accurate speed recording. Good info on recording also on gpsspeed

Not sure if this was mentioned previously, but PPC baseplate shim vid talked about some shimming their baseplates when speed wining to allow a more nose up ride so any accidental touchdowns are more likely to skip back up rather than dig, and also allow more front foot pressure style riding.

Axis provide a 3D Printer file for the Negative Shim (-1 degree): axisfoils.com/collections/all-wind/products/axis-foils-3d-printing-files-1-degree-rear-wing

I got a friend to print one of them for me, and it made a big difference to the liftyness of the ART799 at high speed, and also the tendency it had to lift/engage really agressively on takeoff (on the kite at least). I haven't tried to go super fast yet, but I have two similar tracks around 41kph (again on the kite) - one before and one after the shim. The second run was a lot more neutral and I wasn't needing to put all my effort into keeping the wing down.

It doesn't seem to impact the lower speed riding at all, at least not stall speed wise, just makes everything more neutral.

I haven't tried it on the ART999/Wing yet - just haven't had a chance - but I'm hoping it will be a similar story there, and then I'll just always use the shim with the ARTs.

Thanks for info and sharing the file!!??

I'll try a neg shim with strong wings.

I really like the Waterspeed App for the Apple Watch. It gives you top 2 sec, 5 sec, 10 sec etc. so you know if that top speed was an anomaly. Also allows you to enter/select 3 types of equipment for each session and enter notes. You can check speeds for each foil etc over multiple sessions. Here's a recent flat water session on the Armstrong 926 and 195 tail.

Really interested issue, thanks for posting! Always asking wingers their top speed, but not everyone cares about this. I really do since I feel winging slower than kitefoiling. Personal records:

1. 22knts on 700hps and 400ha rear, 90 mast, custom board of 80L, Vayu Vving 4m and 15-18knts of wind.

2. 21knts on art999 and 420ha rear, 90 mast Vayu Vving 5.4 on same wind conditions.

Just get art799, but havent tried yet, really looking forward to have wind conditions. I saw Foiltycoon posted on instagram 26.3 knots on art999 with 400 progressive rear. I have not heard good things about these new progressive rear wings, but would like to try them.

I've been looking at the art799. Would be interested to see how you go with it. I would be happy to do anything over 25 knots of speed on a wing. That is my goal

I think it is possible, especially on these art foils. Everyone seems to say they are very fast!

I have both ART 799 and HPS 700. I have been having more sessions on the 799, but still prefer 15-19 knots on the 700. I also take the 700 down range to about 13-14, but pointing upwind can be a bit of a struggle. Still. I'm doing 20 knots in 14 knots. Love being able to whip into a turn and spin out in super tight turns. The 799 is fun, but I'm still not sold. I want a 599

I am coming to wing-foil from kite racing (regularly hitting over 30kn) so the speed stuff is interesting to me. I have only just learned to water start reliably on the wing-foil but can gybe and foot change once up. Last week I raced at JBSC in Perth which was interesting, one of the wingfoil racers in between racers tried a kite-foil race board and foil combo and water started it as a sinker with his 6m wing in about 25kn, he got up no worries. But he said it actually wasn't much faster than his current foil, which looked to me like a wind-foil racing setup with long carbon mast and HA large wing etc. I think he said he's hitting the high 20s.

In Europe the wing-foil race scene is taking off, I work with Gin Kites and we are developing a race wing for general sale, we are hoping that is a growing market. The regular free-ride wing is coming out next month (called the Detla - I'll have demo wings for anyone to try) and the race wing the "Alpha" is coming out in April. ginkites.com/en/produit/maax-wing-racing-coming-soon/ if you click on 5m you can see a picture of what the race wing will look like and there are also pics of the Delta wing on the same site. My intention is to keep working on my starts until I can launch my kitefoil race board/foil (Levitaz R5) and to see how fast I can go with the Alpha wing when i get them.

I'm surprised not more people have joined the wing group on ka72.
