I have one for sale if you are interested!
Yeah I feel like compared to wake style the loads foiling are a lot lower so you could have a lower diameter line and fit more on the spool.

My winch has 500’ of thin spectra line. Opti sail tie material basically. Super thin and lightweight!

Yeah, we built our original wake winch with a spool that held 1000 yards of dyneema. But I bet we could cut the diameter in half…

It’s also supposed to be a twin fin!!!

Another instance of this, first time I’ve seen it look like it could work.
600 cm², but at what I’d imagine is almost 1 AR, which I think we learned in this thread or another means very inefficient at producing lift
I might chop up an old foil and do this…
How about a dual mast set up like a Beta foil for down wind racing
Could go super small, ≈4mm thick masts at approx 400mm spacing.
A lot of the traditional fuse and front wing bulk is for torsional rigidity. With two masts you don’t need this so a lot of this bulk could be reduced or removed entirely.
You could also add an extra wing between the masts to assist in take offs.

I think this is a great idea. Twin masts would really manage the two loads on the mask better so you could design much thinner mass and maybe break even on drag and it would definitely be better for the front wing structurally lead wing aspect ratio get higher than the current material limit
Yes agree, feels like we’ve hit the structural limits of single mast, and bulky fuse to support it. Would be super interesting to see what someone could come up with, but I imagine we’ve gone too far to realistically have something competitive given how far the single mast has come.
Roping beta foils into a race version of their foil would be very interesting.
In a different direction, you could expand on the benefits of two masts, by having deliberate surface piercing foils so that as you get higher on the foil you have less lift.
The bottom middle section could be swept forward, which would give you more stabilising lift as you drop down and engage the angled planes.

The new Uzips look real nice.
Pros - makes skids easier
Cons - more sharp bits
I wonder. I do love some innovation. I feel like it might not provide much airfoil lift, but a nice skid surface..
According to this video, the Blackbird has the chines on the fuselage for reasons that have nothing to do with foils (lift at mach 3, radar deflection, nose stabilisation)
that is cool… so the lift could be from the beefy fuse cross section effecting an airfoil shape
F-one launching little tracknut lockers, seems reasonable, I’ve not loved those ribbed m6 nuts on the FCS tracks, but the FCS tracks are absolutely terrible, so shallow.
A more important question, F-one don’t have slotted masts for the bolts. Is this the way forward? Anyone comment on how much that impacts strength? It’s irritating on Code, but maybe it’s a worthwhile compromise if you have these nuts?
Longer openings at the track boxes is an even faster and cleaner solution to the closed holes mast plate “problem”. Leave the hardware on the mast (only one set of hardware for multiple boards needed), align the T-Nuts (not even needed, with the right rubber/plastic thingy), slide in and screw it fix (less turns needed, than the lockable T-Nuts).

I had similar “locking” track nuts on my wing board a few years ago. It was nice as my mast at the time didn’t have cutouts so it was simply a matter of setting the foil onto the board and tightening the screws. I no longer have a need as I’m running a Tuttle on my wing board and I prefer the tool-less option of the wingscrews on my prone setup.
