Re: Twin Tip Hydrofoil

Thanks for your comments guys, its good to know I'm not talking to myself ! Here's a bit more on foil design... Ive seen all the complex calculations to do with the foiling all things that go in the water, from the very complex NACA designs and consideration of lift Vs drag And I compared the lift V...

Re: Twin Tip Hydrofoil

The blue one at 11 o'clock is one of the extra small one at 8" wide X 18" long with 118 sq in. The yellow one in the middle has a total area of 277 sq in but that includes the side arms (@58 sq in), the middle section and the angled beams that connect the middle to the side arms. Everything is measu...

Re: Twin Tip Hydrofoil

Thanks for the comments guys. With the twin foils I did play around with AOA all the time as well as setting them at different heights so the front foil didn't create turbulence for the trailing foil, but now with a single foil there's no AOA , just parrallel to the hull, it makes it easier to know ...

Re: Twin Tip Hydrofoil

Thanks Hawaiis, heres a bit of theory of mine. Any shape can be used for a foil and the shape carries its performance characteristics...wider foils are more stable side to side and longer foils are more stable nose to tail, but how do you work out the best dimensions ? Over the past decade this is w...

Re: Twin Tip Hydrofoil

You're all right, those foils are mine and the struts need to be an appropriate length for the application. Here's some more of mine or if you google Shortboard hydrofoil there's more there in Images. http://i1364.photobucket.com/albums/r734/clintsca/ef33ef94bcf207dd421ca952907f2cfa_zps0374d1d5.jpg ...

Ive been using foils like this in the surf but instead of two lateral hoops I'm using one longitudinal hoop. The longer the longitudinal section the more stable the lift.

Re: PVC pipes to build an hydrofoil?

I admire your ingenuity but I think the hydrodynamic forces are a lot more intense.

Surfing hydrofoil

Drlightwind, the foils are a different shape from flat water to riding the circular wave form. If you've had a look at the Horue guys from France, you could build a functional kite foil based on approximates, its not overly technical to get it right. Keep the length of the fuselage about 700mm for s...

Re: MHL Lift Hydrofoil Kitefoil Wobble

Good point Hawaiis, if they've improved the product, did they send you an older model thats inferior ?
Im guessing you paid full price for the less than perfect foil ?
