How to build your own surfcraft hydrofoil.

The “conventional” foils are maturing I think: check out this riding on/near the face.

Pretty good by comparison to the way out on shoulder rides seen before.

And though on a surf foil he is being pulled by a kite, which usually makes it harder to stay in the wave.

true, it’s big arcs and trimming in mush, but some progress is happening.

i still think surffoils’s unconventional foil layouts are a direction that needs exploring for more vertical surfing and hollow waves, but this is looking pretty relevant to many surfers (possibly including me) who ride mush and/or do more trimming and swooping than slashing etc.

i am pretty convinced of the advantages of a single strut despite its engineering challenges, loss of drag is the sine qua non of foiling. Otherwise we could just surf a normal board with a step stool   attached to the deck!

and again, nice looking weld!

Thanks for the welding praise guys !

It’s obvious that conventional foils don’t sit in the tube or like steep waves, even when Kai Lenny rides some huge wave it’s always out on the shoulder. No offence to him or Laird but current foil designs are extremely unstable in the tube, that’s why you never seen them pulling in.

That’s also why I only have to post the same pic or pics off the low tech Vimeo videos I did years ago of pulling into tubes one after another.

 I know I’m not a big wave rider, I know I’m not sponsored by Red Bull, but that only  proves my foils are even more amazing. I did it years ago on a shoestring budget and still years later all the conventional foils by all the makers worldwide can’t touch the level of performance of my dodgy ply foils.

 I would challenge them to take off on a hollow beach break, bottom turn, snap, stall in the tube and then blast out of tube after tube like I’ve done in the videos from years ago. They can’t.

I remember the surfboard design frenzy of the 70 and 80s that died a corporate death because invention doesn’t guarantee sales. So now everyone is very cautious of stepping out of line.

 But they will progress and of course herald their foil design idea as a unique concept because there’s money in calling yourself a Maverick. Not so much in admitting you’ve copied a fat surfers decade of research that you saw on Swaylocks. Theres already a new foil that’s slowly moving away from the straight lateral foil.

But I pride myself in knowing that I’ve done it cheaply, using whatever sat around the shed, spending more time thinking and building than anything else. And if in the end some of my ideas make a better product then it’s good to know I’ve had some influence.

 It’s just a pity that Terry Hendricks wasn’t here to see this all happen, he would have been very impressed.

Sorry gdaddy, not personal, I was just trying to reply to everyone.
