AFS Enduro - Yet another whale style wing

I recently had the opportunity to take the Enduro 700 for a downwind run in the bay. The setup included an 80 cm AFS UHM mast and a Silk HA 38 tail with the long fuselage, all mounted on a 75L mid-length board. I’m a 195 lbs rider.

This is NOT a review - Just some first impressions and observations. I feel there’s much more to explore with this setup.

My reference point is the Lift Florence X 110 with the 21" Flow tail. There are many similarities between these two setups. The most significant difference is the aspect ratio (AR): 13.1 for the Florence X 110 compared to 11 for the Enduro 700.

Pros:

  • Great surfy feeling; it carves and turns really well, even on this downwind/glide setup.
  • Super stable at speed, chop and during tight turns—nothing seems to throw it off.
  • Excellent pitch stability.
  • Performs well in mediocre, messy, short-period wind chop of medium fetch.
  • Efficient pumping; it generates good speed going up and over steep bumps while chasing good lines.

Cons:

  • Higher take-off speed compared to similar-sized foils.
  • Higher stall speed compared to similar-sized foils.
  • Sensitive to changes in angle of attack (AOA), leading to abrupt stalls.

Another characteristic of this foil is that it doesn’t “load-up,” which could be either a pro or a con, depending on your preference.

Coming from setups that do load up, I found this required some adjustments. While riding upwind against steep bumps, the foil maintained altitude and wasn’t affected by the energy at the bump apex. For my riding style and setup (shorter masts), this was a shortcoming, as I wasn’t able to harness the energy of the bump to achieve a better upwind angle. I also needed to constantly adjust altitude to avoid hitting the apex of the bump when coming up the trough, especially since I was using an 80 cm mast. With my usual foil, I could slow down considerably to mitigate steep faces and still maintain a good upwind angle without stalling.

I also had to adjust my tack technique due to this behavior. I rely on my foil to load up and carry me through the turn and over the bump when going upwind. With this foil, even if I had enough speed to carry me through the wind, I also needed to adjust altitude to avoid hitting the bump coming upwind.

Another adjustment was needed on tighter turns. If I overshot the pocket, I wouldn’t have enough lift to complete the turn and would stall right away. With my current setup, I can rely on the foil loading up during the turn to compensate for my lack of skill.

With the Enduro 700 setup, it feels like one has to rely more on speed to perform well.

Once I worked through these challenges, though, it turned out to be the most fun I’ve had in recent memory on this mediocre run.

I’m planning to pair it next with my KD Marlin 15" tail, set at about 2.5 degrees Angle Of Incidence. I measured the AOI of the HA38 tail and found it to be 0.5 degrees, which is very low compared to every foil I’ve ridden.

With the extra surface area and increased AOI of the Marlin tail, I’m eager to see how the behavior changes.

Please share any advice on how to maximize this setup.

I’m also curious to hear what the 15” marlin will do. I’ve not tried the 700 but I’ve been winging and fd’ing the 900/1100 for a bit now with either 14”or 15” marlin, and at times have felt very low stall speeds. Incidentally, I got the ha40 tail in the mail yesterday, and noticed it has a lot of aft loaded section, similar to the K2 tails. I found that switching from the K2 tails to my marlins, I had far less problems with dropping out. My wonder is if the aft loading section(marlins have but very slight compared to k2/afs) effectively lowers the surface area at low speeds since it curves up with the flow of water? I also got the kd race tail which is similar size to the ha40, so I’ve got some testing to do.

It’s finally here!!! 700 enduro -
Now must ENDURE the anxiety of waves or wind coming back so I can test it - till next week.

At first sight, must say the fitting of the fuse to fw connection is really clean and tight.
This wing only compares to the silk with the bumps, other than that it’s really different, way sleeker/thinner - leading edge line is more comparable to the PURE line in thinnes - wingtips end differently - camber exit is very clean and subtle, no radical weird curves.
This thing looks and feel very high perfomance and fun! hope to be on water soon.

Does anyone know the decision behind Silks being built with full fuselage but the Enduro’s having a detached fuse? Enduro is tempting now that front wings are only $769 + $419 fuse. And travel ability much easier.

Did AFS decide that the inconvenience of the Silk wasn’t worth the benefit? Or is there something specific to the wing style that drove this difference?

It could be that they thought the higher span + permanent fuse would be too much inconvenience. But I hope they intend to use this platform going fwd. In the afs video Laurent mentioned he actually wanted to do something closer to the silk, which I interpreted as a 9ar silk v2 or the like.

They talk about that decision in the Generic foiling podcast #87. They don’t say exactly why they moved away from monoblock for the enduros but mentioned a couple of manufacturing challenges with the full monoblock fuselage/wing.

There’s a French law that limits the weight of a mold that you can move by hand, and they had to cut their molds into a T shaped to keep the weight under this limit. Also, larger molds require larger presses.

I expect they’ll make larger monoblock versions of the Ultra 750 if they can. It’ll be interesting to see how large they can get.

Let me know how the 700 is!

I just wrapped up my first Fiji trip and surf was pretty small the past 3 days - I rode the 900 with the short fuse and breached tips (not on purpose) 3 times on a single wave, recovering every time. Pretty forgiving wing!!

What tail you using?

Silk HA 40 during that session but I’ve also been running the Uni P13.5 or chopped P14.5.

All work well!

Going to try the Silk HA 38 next.

Just got to finally give it a try to the 700 with 38HA.
Decent power waves and clean beautiful day to properly test the glide of the foil.

It does feel like a merge in technology of the Glide and feel of speed of the PURE line (used to ride the 800HA PURE on these waves too) and the smoothness and loose carvy feeling of the SILK.

My impressions having the SILK 850 as a comparison point.

Low end and take off might be a bit better on the 850, for obvious area size reasons, but still feels like a 800 whatever foil, the take off on steeper waves feels more like the Silk650.

Pump does require a bit more cadence but once you put the effort of going high up on the mast and at cruise speed it’ll go as far as the S850 and pump feels more like a PURE (had to take a couple flights to get used to it but felt natural quickly).

Not a beginers foil obviously, the 850 will be better suited for progressing in that range of small foils but still, felt really natural to my and an easy glider.

Going fast feels more comfortable and definitely improves my range of waves for getting bigger faster waves than the SILK850 and yes, I’m betting on put a bit more effort and technique to compensate for the ease of use of the 850 on the smaller waves.

Used it in the same mast position as my silk 850 and with the shorter stab position, this felt like a more playful on the pitch to add more playfulness while carving on the waves, the silk 850 only haves one position (not sure if the latest ones have a second one).

Rolling does feel faster and more aggressive on the S850 since it gives more front foot feedback, but I think I might have to play a bit with shim or mast position adjustment on the E700 so I can find different feelings here, or just adjust my riding to carve harder. I really like it being more subtle on the front foot feedback and more balance feet pressure at higher speeds.

Hopefully in less than a month we get proper downwind conditions to test it in downwinding.

Hope this feedback makes sense :sweat_smile:

Here’s one vídeo clip I made, only did one since I wanted my hands free to adjust my balance to the foil.

Were you riding the shorter stab position on the short fuse or long fuse?

Thanks for the detailed review! I just put in an order with the Foil Shop and hope to test it out in the next few weeks.

Epic. Can’t wait to feel it out!!!

Ben Tayler got some beautiful footage of me riding the 900 like a kook a few days ago - really enjoying the wing so far. Was riding a friends board and couldn’t quite find the right mast position but stoked to dial it in on my board next week!

What the hell is this at? Beautiful water! But the 900 is epic!!

Just reporting riders’ report in france on the whatsapp group, a few people have tried the ha and silk tails paired with the enduro and said that the silk tails add some low end, pump tolerance when proning, and a more carvy feel, for the price of a bit of glide… so ppl tend to favor the silk tail on enduros and ha tail on the silks, to balance out their behavior, silk being the carver and enduro being the glider. Disclaimer I am just relaying the info.

I finally got out on enduro 1300 this weekend in some fat gutless semi-breaking swell. I was able to run it back to back with my axis 1201 in the same conditions with the same tail (KD race) because that’s been my reference standard for big foil glide at 200lbs rider weight.

I’d say the 1300 matches the glide and pumping energy, possibly slightly better low end, but at the same time feels stiffer and turns better on the wave. Also more stable at top speed in my opinion, it can get up and go fast. Still surfs like a very big foil, that can’t be avoided. But this will finally knock the 1201 out of my rotation.

Setup was Cedrus Evo 72.5cm, short fuse, KD Maui race tail in shortest position, pretty flat shim

How does turning the Enduro 1300 feel compare to the Code 1075R? Glad to hear you found a foil that works for you!

Ahh Hummus is like a skate park for foils.

I can’t wait to get my enduros out to rhe surf to test!
