I just ordered my X-Carve, and it is supposed to arrive tomorrow. Very excited. This will be for my hydrofoil project. I am a long time windsurfer and kitesurfer, and want to build my own hydrofoil. [![](https://img.youtube.com/vi/JMROOeHbkps/maxresdefault.jpg "HydroFoil Kiteboarding") ](https://www.youtube.com/watch?v=JMROOeHbkps) A friend of a friend of mine has a CNC machine and made some molds for me before, but he is very busy, and hard to reach. So I decided to get my own. Here are the models I am working with: ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/1/0/10edeffc5d321a41f31578bc09b065bf16bbcc1b.jpg) ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/1/0/10edeffc5d321a41f31578bc09b065bf16bbcc1b.jpg) ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/2/c/2c8278e5693f298d89d5867c9cd033f8acce4854.jpg) ---

Version one was years ago. I had molds made by a friend of a friend who had a CNC machine. Progress will be faster now that I have my own. ---

Dude, that’s very cool! I love outside of the box projects! As a sailor interested in the America’s Cup, foils are of great interest to me and I love making stuff out of carbon fiber. Keep up the great work! One of the reasons I wanted an XC-1000 was to be able to make NACA blades for dinghy racing and this is very closely related. ---

You have GOT to put a hydrofoil on one of those things. Like the foiling Moth or the Hydroptere. I was using a friend’s hydrofoil yesterday, and managed to get up and flying on the foil a few times. Its an amazing feeling. My foil needs some redesigning. I know I made the stabilizer too small. And I have a few other hydrofoil projects in mind. Maybe something with a small 10 hp motor to get around the lake with. Hydrofoils for a big race windsurfer. A hydrofoil bike. I could do that! ---

The previous stabilizer was too small. The board wasn’t stable enough. So I rescaled it, carved a new set of molds on my X-Carve on July 4, and they are ready to lay up carbon fiber and epoxy today after work. This machine is really making this project go much faster. I will have achieved 3-4 days from finished design on the computer to finished product ready to go on the board. LOVE IT! ---

So far it worked pretty good. This is my prototype, so its not as good as the commercially available hydrofoils available. But I got some rides in. ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/9/c/9c9360dfbe48113e39593af20c031178dce40963.jpg) ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/c/e/ce534c1b9e1134117b16b7c5aede6fb5169dc3da.jpg) [![](https://img.youtube.com/vi/l2J-P3MITMc/maxresdefault.jpg "Hydrofoil Conneaut July 9") ](https://www.youtube.com/watch?v=l2J-P3MITMc) Next I will be redesigning a lower aspect front wing. This, along with a longer, better fuselage should make a much steadier ride. An issue with the old windsurfer as a board is the convex deck. This makes it harder to prevent roll. It was harder to apply pressure to the board to keep it from rolling sideways. I will be building an entire new board from scratch. This includes the mast (vertical strut) which is far too flexible, the fuselage, and the front wing. I think the stabilizer turned out perfect, so I may not need to make a new one. ---

Nice vid and idea! the howl from the wind through the lines is haunting, I might use it for halloween this year This gives “getting it up” a whole new meaning! Please keep us posted on your progress. ---

I just cut a mold for a lower aspect front wing. ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/2/8/28baaa604d0848137c135a08f4c445fcd0c66742.jpg) ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/0/c/0c666c1777f7c77cf772a2d9d252247dd5c12305.jpg) ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/4/1/414972cbdad33ea319cb90b0e860c76f75543af4.jpg) I just made a new fuselage based on my experience that the joints between these parts should be flat surfaces. You can see that the top half of the mold has a flat area to connect to the fuselage. ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/4/0/404a29189c882baf3adb0d6a6d35ea08f31b0cc1.jpg) ---

This just keeps getting cooler! 🕶 Can you model a saddle into the wings to increase the bonding area? ---

Wow. What bits are you using on the foam? I have not tried Styrofoam before. [Next page](https://community.inventables.com/t/hydrofoil-project/38777.md?page=2)
