So you know the current commercial surf, kite and SUP foils are fully foiled and straight across right ?
Well Fanatic have brought out a much flatter and curved foil. How great is that.
It’s not exactly the same but similar to these ones I made in 2008. And rides the same with a Higher top end speed.
I’m happy to see that my foil concepts are validated and that they’re catching up. Now they’ve got the flat plate idea, next is the low aspect foil design.
brilliant. Still following this.
All the best

And another guy has found that you can ride a single foil and the rear stabiliser isn’t needed.
Did that about 10 years ago too. I hope Terry Hendricks is watching all this.
You mention the struts need to flex a little bit. What are you doing to get that flex? Also, out of all of your (genorous) examples, what foil shape/setup do you like the best so far?
Send me your dinged, damaged, and yellowed.
Hi Monkstar the foil gets some erratic forces from the side when you’re in the tube . It kinda pulls and tries to throw you off. And the longer the mast / strut, the greater that force is. I think it’s because the foil rides in and out and semi submerged in the wave so there’s never an even balance. To smooth that out I use 6 mm clear polycarbonate ( because it’s almost unbreakable) or polypropylene ( because it’s easy to work with) And both flex enough to smooth out the ride.
The struts fit into FCS plugs on the board and are bolted to the foil. It’s not hi-tech, but it works.
The best foil arrangement varies as the designs continue. I used to think I had something amazing with the Holey foils but I’m working on a Modular version that’s adjustable for different wave size or skill level. So that’s still a work in progress.
Single strut setup.
Use any old snapped board, mark out holes from the foil base.
Drill down to the deck ( but not thru) and drop in resin and threaded rod. The resin soaks into the foam and grabs the thread on the rod.
Then put on some nylon nuts and a foil and you’re out the door.
Cool! I assume you trim the threaded rod after the nuts are tightened? Might want to use a metal nut as a thread chaser to make sure you can get them back on if you ever need to remove the foil, at least at first.

Yes I’ve cut them down to fit the baseplate, nut and a few mm.
the threaded rod is solid as a rock, it’s not coming out without a fight.
I prefer multiple struts over a single mast to spread the forces but a single looks neater.
Single mast on DK / prone board.
Ill have to make a new test sled for the single mast, it’s not what I like, but it’s more about fitting in with the current popularity of single mast setups.
i might even make a foil of my own design that fits onto the commercial masts.
That is a very nice looking weld job at the base of that aluminum single-mast.
