Honestly both are a pretty bad solution.

Tuttle works best when the vertical loads are taken by the roof, we've known that for years.

Where winging and small sail freeride windfoiling diverges from IQfoil/other racing is the sideways leverage which is rather a lot.
I don't see Tuttle boxes being designed with walls that are really built to take these forces. They need some ribs running horizontal through the entire ABS foam block, not just thick walls.

If you’re just foiling along bolt upright with a small foil on then you’re only going to be applying lots of vertical force. But if you’re going to head out and jump/twist/surf swell /turn corners etc, then you’d wanna hope they’ve built something very damn solid next to that long box.





I agree - if you're a lighter sailor windfoiling with a tiny sail and holding the boom with one hand half the time, I think the forces/pressures on the T box/plate are way less than if you're 80kg+ foiling powered up with bigger sails in big swells, using the sail power similar to a bump and jumper 😀

An i see broken foil tracks almost every week...



only as the manufacturers use rubbish longboard boxes and-or crappy install. Done right it’s a strong as DT and similar weight. Using surf boxes and the ridiculous Gorilla glue installs that surfers did a decade ago (that unfortunately a lot of folks still follow) is just asking to fail.


companies like DT as it’s a more simple install to get done by Asian factories.
Combined with a box that’s really easy to mould in big quantities at Cobra.
With most racey foils being DT that’s why it’s prevailed.


people come to me all the time to get tracks put in for adjustability and love the result. Seems a lot of folks want adjustability. I’ll be keen to see if the adjustable Tuttle is strong enough but with Slingshot pulling out of Oz I dunno if we will see much

My Mozzy installed deep tuttle is still going strong😁

Slingshot pulling out of Australia?
Really who's telling you that?
I really don't think that's the case.
Yes they are not in the wind foil game anymore, but that's it.

Oops I stand corrected. The windsurfing sale resulted in them going away of course but a quick google shows me plenty of action in Oz with their other stuff

Box strentgh - anyone exercise the fine art of dockstart?
I do - and trust me, the forces are brutal. Probably worse than iq foil during gale winds
I pumped through a welded AND bolted alumast/fuse connections a couple of years ago - double stainless M8.


to the point - your on an 7-8 l board with tracks. No tuttle, the board is around 3 cm thick. not much else than d cell and carbon around it. Front wing in the range of 1300-1600 cm, 2000 cm2 of volume, massive lift. You get lots of sessions, you jump on it, you give it a hard time every time.

Strength of the twin tracks, any direction, is not an issue.

btw - wingers don’t suffer from the rig pushing down in front of straps. I reckon this makes the need for adjustability less. However, even within the same brand of wings the cl might move around 1-2 cm, enough to notice if u ask me, even for wingers

So many uninformed opinions...

I ride in a wide variety of locations, gear, and conditions..the only time I move my foil is when I move my footstraps. In fact, I am using locking t-nuts on my windfoil board to assure my foil goes in exactly the same place every time. My wing board uses slingshots RTS system which also assures repeatability. Anyone who has seen the inside of my van would never conclude that "that's not a quiver"

Plates were an improvement in the early 'wild west' days of foiling when everything was different and foil performance was poor. Fortunately that is no longer the case. If you are needing to constantly move your foil position you either need to update your foil system or improve your technique.

As for Tuttle not being strong enough; what about iq foil, kite race foils, or wing race foil. All of these disciplines successfully use Tuttle boxes. While the loads that kitefoil racers produce are scary, their equipment isn't.

Yeah, plate it good for allow people to find the preferred spot for their specific foil on the board they own. And is it just tradition that keeps the PWA foil racers on tuttle? I doubt it, if the plate was stiffer or better the PWA guys would be on it. Having said that I ride plate and I would say its more about the quality of the mast overall, not the connection.

A single track system. Well, at least it’s adjustable but looks weak. Anyhow, nice to see some new ideas
