Althought foiling is much more than "going fast" on a straight line, it may be interesting to figure the speed targets for given wind strenghts while on beam or broard reaches.

I agree, just got a free gps app made for windsurfing, Windsport Tracker to do exactly that with my phone.

Using a Yeti waterproof fanny pack to carry my phone in a waterproof case, have tested the fanny pack and it is waterproof, has a neat velcro and magnetic closure system.

I tried that app, but it would only track while my phone was unlocked... Maybe I missed something.

There are a lot of ways to record tracks and scores. What i meant is that it would be useful to know the amount of wind (and possibly the water state) during the single sessions. When you score 24 kts vmax in 10 kts wind is not the same as if you scored the same speed in 18 kts wind...

I used a smallish, soft, flexible drybag to protect my Android phone. After a session I was horrified to find about a tablespoon of water in the case. I'm surprised and pleased that it still works. Since then I bought a Garmin fenix 6 and now I use the "Bike" app. It logs my speed and automatically uploads to my phone when I'm off the water and within distance of my phone. It's funny to see my so-called "bike paths" running through the middle of the harbor.

It's not perfect. During the winter I'm considering writing my own Garmin fenix app since I haven't found anything out there that I really like. It should be fun. I'm making a list of other winter projects such as a sail drying stand and a new beach cart. Sorry if that's going way off topic.

I often do 54kph ~ 29 knots in 12-14 knots of wind. But I've also done 41kph (22knots) in 6-8knots of wind, so thats 3-4x the windspeed!!

That's good speed

There's a couple of guys here regularly doing 30+ knots on flat water with tiny race wings (around 550 cm2) and race sails.

Are you able to get your speeds on freeride gear?

That's it!

This is not the right place (many dedicated sites are) but, as we're here, used gear?

Above 15 knots I can get those speeds on freeride equipment, my record speed is 29.6kts, and I did that with 4.9 wavesail and an F-One Levo Carbon 900cm2 freeride foil.

Below 15 knots I need my big sail to go fast, but I dont like my racing board with my freeride foil, so in the 6-15 knot range my fastest speeds are always with (PWA level) racing gear.

I tested it walking around and it tracked me on a google map, maybe need to make sure the phone is not on energy saver mode?

Your F-One Levo Carbon 900cm2 looks fast!

Have you had the chance to ride any swells?
I'm curious if a high aspect 80cm wide foil can carve tight turns

Some prone foilers are moving back to medium aspect wings (from HA) for a better speed/surfing balance.

I have dabbled with using it in (north sea) shorebreak. Would say there are foils which are more ideal for that kind of purpose. For example, I think your I65 is perfect! The Levo900 has a slightly blocked feeling halfway through the jibe for example, which you have to push through. I'm very used to it, so no problem, but in the development I've had a few months on a more curved / lower aspect 850cm2 wing, switching back to the Levo left me having to adapt a little because of the "blockedness". I think its due to the quite outstretched flat section in the center of the wing.

I think especially for foiling in small to medium sized waves there comes a point where you just dont need the efficiency, and can gladly exchange some efficiency for playfulness. If you look at the F-One Surf range for example, the smaller we go, the more low aspect and rounded the wings go in the "Gravity" range (surf/sup). The 1500 and 1200 don't even have a flat section! These wings are fast enough because of their small size, so why opt for more efficiency when we don't need it?

Thanks for your insights

I agree with the turning limitations of HA.
I built a flat 82cm wide high aspect wing (pretty rough but useful as an experiment) and found the same slightly "blocked" feeling mid-turn. The wing also tended to skate through a turn more than carve.

I think to turn well for windfoil wave riding or downwind carving around 65 cms width and medium aspect seems optimum for a flattish wing with wingtips (Infinity 65).
Wider wings (Infinity 76) still turn well with some anhedral - which imparts roll instability and also helps a little in preventing the wing-tips breaching when carving hard.

Popular foiling has now been around for about 10 years - I wonder whether there are major developments to come or whether we can only expect small incremental improvements?

Some prone foilers are moving back to medium aspect wings (from HA) for a better speed/surfing balance.

I've been using the i65 and i76 Slingshot wings and a variety of high aspect Lokefoil wings.

In my experience the high aspect wings are capable of carving tight turns. But the big difference is with the wing span. On a 80 - 90 cm wide wing I've got to ride lower or I'll lift a wing tip when carving. That gets worse as the water gets choppier. So in reality you can't carve wide high aspect wings as tight on chop unless you've got a really tall foil mast.

The i65 is relatively high aspect but because of it's small wing span it means you can carve really hard before the wing tip gets near the surface.

This guy is carving well on a short mast and high aspect wing. But it's really flat water and he's very skilled at just scraping the surface with the wing tip!

As a pretty new foiler, how do you know the limit here with breaching the wingtip? Do you start feeling it? I get some sensation from my foil, but at the moment I'm too preoccupied with balance to think much about what I'm feeling under my feet.

Sometimes you can hear the wing tip starting to break the surface if it's not too windy and the water is flat. If you're lucky the wing tip just breaks the surface temporarily and it'll feel like the board wants to right itself as you lose lift on the outside edge.

Normally though you just get used to what you can get away with for a given wing.

A freeride wing that goes 29kts is quite amazing, any speeds over 20-21 on my freeride gear is rare, sounds like this Levo must cruise at 24kts
Are you able to tell me what is the wing span and cord depth of this F-One Levo 900cm2 freeride wing,

Its 80cmx11.3cm, 7.1 aspect ratio, true surface area 888cm2.

I'd say in terms of aspect ratio it sits right in the middle between a waveriding type wing (AR of ~4.5), and a racing wing (AR of >10), but with a very efficient (read flat & fast) profile.

In the coming months I'll pair my Levo Carbon with a 220 stabiliser / 7.2AR (instead of standard 300/5.4AR) to see if F-One will be the first freeride hydrofoil to comfortably cross the 30 knot barrier. I've passed it once or twice, but mostly I get stuck in my runs at around 29.6-29.8kts.

Thanks for the info, very impressive stuff from Levo
I checked my fastest freeride wing and it's 80x21cm so I guess I can't expect your top end
