At $200 I would gladly fit one to an oldish board

Hey Surffoils can you take it off and place an another board?

Saltman,
you can swap the foil over to another board in a minute. If you've done a small repair you can install the foil.
So that 1990 Gunther Rohn under the house has a new life to live. Any board will do, you don't need to buy a specialty board, an older board works just as well as a brand new one when you're foiling.
I've costed the whole foil kit including postage and a few spares at $200, it's about $1400 cheaper than other foils. The spares are included because life's like that.
The concept was to make it from common materials and avoid any custom components so it's as affordable as possible.
I wanted to make it a real science craft for pros and surf geeks but there's a better market in making it a $200 toy.
It's a great and cheap introduction to foiling for anyone.
It's way safer than any other foil.
It's very easy to ride from the first wave.
Works instantly as long as you've moving forward.
It's such a simple design that if you break a component you could easily make a replacement part
( which means you can modify and customise it later )
It's priced as a toy but it has about 13 years of experience and prototyping behind it so it's got some solid knowledge built in.

The hard thing for me is choosing when to step away from tweaking the design and start getting them out for people to ride.

The foil can be made of polystyrene so it's a safe kids product.
Or make it from carbon fibre and ride it everywhere else.
So yes.

What the hell is that ?

I started making surfing hydrofoils in 2005/6, now I'm into the hundreds of versions of prone, shortboard, longboard, SUP, handplane hydrofoils. Just Google 'hydrofoil shortboard' or anything like that. There's tons of pics , videos on Vimeo. Just your average backyard surf inventor making stuff.but all of a sudden it's really popular.

Cpt Caveman from here has ridden my paddle-in shortboard hydrofoils back in 2013.( Pics here on Realsurf.)
I think Cpt Caveman was the first person to paddle in and ride a shortboard hydrofoil in the surf. Ever.

And that's Just 4 years before Kai Lenny did it first if you believe the Red Bull advertisements.

Here's the Cpts review from this thread back in 2013.
Cpt.Caveman wrote:Hi guys, I'm the test pilot for SurfFoils chiming in to talk a little about how it rides.

I've been riding the square yellow aluminium foil on a bodyboard to get started, mainly to get my head around the dynamics of foil surfing versus regular surfing.

Its been a pretty amazing experience so far and I'm very thankful to SurfFoils for having me on board.

I won't comment too much this early on, but its a very different type of surfing to what we are all used to. Its very different to "surface planing" which we are all more than familiar with in surfing, such as getting the speed from the drop in your fall line, and then pressuring a rail into a bottom turn creating lift and speed around the water surface area to project along the wave. Connecting turns "cutting" into the waters surface.

Its more like surfmat riding, or maybe even bodysurfing, where you are actually surfing the power WITHIN the wave, underneath the surface of the water (at low to moderate riding speeds that is).

Once you get a nice angle with the foil at takeoff and pressure the foil into that energy under the water, you immediately lift up and takeoff with a buttery smooth speed and feel. The power seems to be closer to the upper area of the wave in a medium to soft wave, and once you have it on tap you just glide along with an amazingly smooth speed that stays very constant provided you keep the angle okay. You can turn left and right, and perform swooping cutbacks, trim along the wave, etc. Seeing as it rides the power IN the wave, I've even ridden a wave than ended up in the channel still surfing behind the unbroken lip on just the swell (not broken wave) for a long way. Its very intuitive surfing where you're trying to feel out the power under the water to get up and running, and once you have it, where a surfboard or even mal would start to fail you just keep humming along at a constant speed until the wave is well and truly dead.

The hard part is trying to find the angles early on to get that energy on tap, and when you don't get it right funny things can happen. It can just immediately "power down" and stop/flop/throw you right off the front like a skateboard hitting a kerb. It can also be effected by sideways power, losing stability and throwing you off sideways. Its pretty funny when things go wrong, its like theres an eject button.

Nevertheless, basic dynamics and feel are in place now and step two is to surf the standup version and learn how pumping, pressuring, shoulder torque, etc. effect the ride. The very least we'll have is a video of it being surfed, being surfed well first surf is another matter. It may be all good from the get-go, but it may require a little practice before any decent waves are linked! :)

Quick pic of the 2015 version.
The side foils give balance like the inside rail and the rear foil is for stability.
Not what I'm riding now but it's a step in the evolution of surf foiling.

Have a look at others converting shortboards into foilboards.
