How We Built an Electric Flying Surfboard from the Ground Up.

I was hooked. Nothing compared to the sensation of flying over water carving smooth, bottomless turns. It’s a feeling so unique; it kept me coming back for more. There was only one problem…I had no one to share it with.

To harness the power of a wave and surf like a bird, although extremely rewarding, is difficult. Not because riding a foil is hard, but controlling the source -flying a kite or surfing a wave- takes skill. To harness that type of power and gain excellent control is something that may take years to master.

So I set out to make it easy.

I started with the simple task of strapping an electric motor to our foils. My team and I took some parts we had in the shop, cut holes in them, bought some parts off the shelf and pretty much duct-taped pieces together. It took some tweaking, but eventually we got our first ride of about 50 feet. 



 
From that moment on, I was possessed. Imagine taking someone that has never dreamt of surfing, deep powder snowboarding or flying. A person that doesn’t live the extreme lifestyle and within minutes they feel it all. They’re soaring like a bird, carving butter smooth turns and experiencing the freedom of flying through the freeways of the ocean, rivers or lakes. That was my goal, but what I thought would take a year to build took a whole lot more.

It’s one thing to build a prototype. It’s quite another to design a consumer-friendly product that’s safe, reliable and completely badass. We couldn’t just buy parts and assemble them. We had to design and build everything from the ground up. The components just didn’t exists. And to top it off, there was no product in the market to reference.  

So how did we build it?

The first few years were a chase. We had to convince the best minds in their field to work with us to build a flying surfboard. And yes... Pitching a flying surfboard is no easy task. But where there’s a will, there’s a way. And after countless conversations, costly contracts and lots of pleading, my father and I were able to convince enough brilliant minds to help us build the components necessary to create the world’s first wireless, electric foil board.

And let me tell you it wasn’t quite as simple as strapping a motor to our foils...

The battery alone was half the battle. It’s the energy source that propels the eFoil over water for many miles in rugged conditions. Batteries can be dangerous when not properly designed and integrated into a system. If you cut corners, you’ll pay the cost! So even though we paid a premium price, our lithium batteries were custom built by the best in the USA to keep cars on the road and airplanes in the sky. Much like commercial aircrafts, our design and construction was based on the principle that it should be overbuilt, reliable and safe.

The next challenge was the hand controller. I was surprised to find out a bluetooth, wireless, waterproof, buoyant hand controller didn't already exist. We had to design, build and test it for the application. Integrating, among others, magnetic actuators, sensors and screens. It was quite the challenge, but well worth it because our hand controller was successfully designed to be an extension of the rider. It works reflexively meaning you have complete control over your ride. By simply pressing the lever on the hand controller the motor responds instantaneously to your command adjusting the speed. It also throttles you back in the event of low battery so you can get back to shore safely.

So what now?

After years and many iterations, we evolved from the “Spruce Goose” prototype with cheap hobby store batteries into a sophisticated craft that has some serious horsepower and aerospace electrical safety standards. The best part is I’ve taken countless friends and peers to our local lake and had them foiling within minutes. Some were athletes, some weren’t, but everyone had fun flying over water.

The journey has been long and arduous. I’ve broken down on many occasions in the face of failure. My shop burned to the ground. Girlfriends have run away and we’ve spent way too much money to get here, but now the fun begins.

Love the movement you have created on this type of new sport/ I have my own DIY Electric Hydrofoil Kit I’m working on as well!

Hi
What weight can the boards carry. There’s a lot of big men out there. Me? 18st 5lbs.
Good job. Real good.

Please consider making a 2 seater slot in the front attachment with a couple of extra foils for river cruising without the wake. Many uk Rivers have wake based speed restrictions to protect the bank erosion, marine property and nesting birds. I’ve been thinking about this for a while and an enhancement to your solution would work well. Please message me for details. Great job.

Hola buenos días desde Sevilla

Me parece espectacular su proyecto, si algún día necesitara colaboración en España, cuenten conmigo para poder trabajar con ustedes.
Espero que le vaya muy bien y triunfen, aunque estoy convencido.
Saludos

It is a cool board, i must have one somday, i remember hydrofoils when i was young.
The fact that it is eletric andt so silent is the best…
I have made eletric rov and things underwater alot, and i know how hard it is, but tecnolegy is better now and components are smaller and easier to fit in.
This is a start of a new type of trawel on sea without yousing a lot of energy.
I think you can do alot whit the propeller and motor so it can travel loger and faster.
Have fun and enjoy the ride ;-)
Regards Rune…
