Screws loosening themselves ?

Would like to hear about different experiences out there, regarding the screws fastening "everything" on the hydrofoil, that being wings to fuselage, or fuselage to mast, or mast to board - if they have experienced they get looser, maybe even lost, sometimes ? Have seen two cases recently, one where...

Re: Any benefit to weight in the foil

I'm hoping those with a lot of experience can chime in here. Do you sacrifice anything when purchasing a very light mast and foil (forget about the board)? I ask because of my experience related to skiing and I'm ready to drop relatively big dollars on my next foil. I'm a long time backcountry skie...

Re: Stall question for high aspect wing in light wind

This thread has gone totally off track now :roll: The lift of both a wing in air and in water, IS because of pressure differences, absolutely no doubt about it. High on the bottom low on the top side. The pressure is very different along the chord at different spots, and different on different profi...

Re: Board balance

In general one advices beginners to have the straps forward (or the mast rearward), for learning to avoid the foil ventilating. Also the reason why many, even on good well balanced foils, learn/start with their rear foot in front of the strap. They will experience less catastrophic ventilation crash...

Re: Stall question for high aspect wing in light wind

Are you asking about high AR kites or high AR foils (wings) or both ? Any (of them) high AR will be more sensitive to sheeting or foot pressure, but perform better so will be able to ride in less wind/speed. It is the rider (error) when they stall, both of them, not the AR (all other parameters equa...

Re: Monofoil or "riding stabless", setup and riding

Not really, as we are talking about stiff glass or carbon wings for hydrofoiling, so not the same "classic" aircraft issues. Tipstall is probably not the same problem as in flight either, for hydrofoiling - so the forward sweep could be tried yes, to see if possible to get working. Otherwise a more ...

Re: Monofoil or "riding stabless", setup and riding

Hmmm interesting, it will have more vortex drag and tip stall easy, but if the tips has higher aoi (and it overall has higher AR as otherwise the vortex will counteract the higher aoi), it would stabilize the wing just like a swept wing with washout (less aoi at the tips) is stable. OR, one could us...

Re: Falling forward on a jump

Exactly - but basically it is all about your timing that is "off" again, just like it was in the beginning you wrote. You got a kite that behaves a bit differently - takes a long time to get dialed in regarding things you "just do" without thinking about it... Just let time go, ride some more, and i...

Re: Depower cleat slips -- any DIY fixes?

So my depower cleat slips and powers my kite up. Have ridden for a year with the power on full as I don't trust it when I depower. So I've tried 6mm and 7mm dynema. I've tried running a section of line up inside the dynema to give it more bite. None of this has worked. Any tips? The cleat is almost...
