Reminds me of the mute button. You started a good thread and your AI spokesperson has ruined it 
Ps- the foam in tracks makes sense, far more so than the slots

I’m curious how much the filling of the tracks improve things? Anyone else tried this? Got to get myself some foam and try it out.

in typical soupy cross-chop that two kayakers had already pronounced terrible. Here is what happened:
Paddling speed to the break increased. Glide and tracking both noticeably better. Not surprising in retrospect — reduced drag is reduced drag whether you’re paddling or foiling.
Setup speed on takeoff was higher. On a low-volume board that previously had the nose diving 12–18" underwater, the speed increase added stability. Two data points in one.
Drama factor dropped from ~80% to ~30%. I was comfortable laying down power on takeoff instead of managing chaos.
Takeoff conversion went from “I’m not sure I can get that” to “my superpowers are nearly back.”
You always have numbers to back up your findings. Any here or is this by what you felt?
There seems to be a lot of push back against this discussion, and I understand the maths is complex and feelings aren’t accurate, but I’m very much enjoying your experiments, Beasho. It’s all foiling, it’s all fun, I don’t think it’s worth getting too upset about.
The first time I used electrical tape to smooth off the join lines in my fuse was the first time I linked waves. I know it probably made no difference at all, but again, it’s all for fun

Please stop using AI slop summaries in discussion forums! People are here to discuss ideas with other foilers, not computers.
Anytime you copy and paste or reply to someone suing AI it is overwhelmingly obvious, and completely detracts from your own research.
Hot tip, there is no easy way to produce a stupid AI long hyphen using a standard keyboard, its a tool within LLM to assist in verifying human writing vs AI on the simplest level. It’s how teachers know their students are lazy (coming from a teacher).
If you’re gonna be lazy and copy/paste AI slop don’t expect any real discussion, constructive feedback, or engaged critical thinking.
I’d rather argue about flat earth with conspiracy theorists than with an AI LLM about foiling.

To be pedantic: option shift - gives you — and it’s not at all a deliberate tool

…and it is something that I use routinely as part of my daily professional work. People assuming that an em dash is an indicator of AI is going to force us all to be less precise in our writing.
Don’t let the robots win.

Regarding your post from December 2025, It looks like you’re still new to foiling mathematics. Have you figured out Aspect ratio yet?
Fundamentals of Flight** — Richard S. Shevell.**
Cornell Aerospace Engineering, 1992. 50% of people were too lazy to graduate. Still on my desk for quick reference.
Page 95. My notes. Bernoulli’s but “Only for isentropic flow.” “Any Adiabatic Flow.”
I slowed the math way down so everyone could follow. No need for AI or CFD.

Beasho, as a fellow alum, for the love of all the water in Lake Cayuga, please put down the laptop for a few weeks and go get some water time my friend.

That explains a lot about the path of this thread. We are expecting AI to be logical!
Its the application of mathematics that determines the quality of the mathematician.
I agree this thread has gone off the rails. I use AI all day at work and will never go back, but the AI response above is gross. I don’t think we’ll get further by arguing about this but just need more real world prototypes and experiments to show how Tuttle performs. Personally I buy the premise and hope to see mast designs evolve!
Anyway, here’s Gav with some Tuttle love:

Let’s get this thread back on track and keep the momentum…
I finished my latest project, which is a build of the latest revision of my adjustable foil box and installation into Kalama Gator. I filmed it all but I haven’t done any editing or talkover yet. The last picture is topside and you can see all the holes, it has 11 indexed positions for the mast, ~5" total adjustment range. I’ve been out a few sessions on it now and super happy with it.

I want to see this edit and also I want to more AI drama (entertainment) so please get AI to do the edit and commentary!

FYI - Some of us live in a different world than you. Besho is in the water 300+ days a year. Collects all his data on every session. And can tell you which foil, fin, board and configuration performed in what location with what conditions. When he’s not in the water he’s crunching the data and building stuff in his bat cave. I on the other hand am the destroyer of equipment. I break it all boards, masts, boxes, paddles and wings. If you ride open ocean in crazy conditions, giant swell, nuking winds, etc… I would suggest you take his advice instead of posting snarky nonsense.

I dunno man, the level of condescension in comments like the ones below is just plain toxic.

How many days do I need to foil Maverick’s to act like a jerk? If I weigh the amount of coffee I drink every day and document it in a diary, am I now a coffee authority?

In the last Generic Foil Podcast, Greg Falck from Omen said some good things about the tuttle. Starting at 2:02:32.
Coming from what seems to be one of the great analatical mind of the foiling world, designing board AND foils. It means something for sure !

The radix looks great too. Can you buy a radix foil box? Is there any mast available for it? Can I convert my mast to Radix if I want to, like I can with tuttle?
The existing mast conversion would be key.
Recently put my hands in a radix and it seems really great on the front end. Just wonder if it can become the tuttle style standard.
