Hydrofoil DIY from Argentina

Postby clauditene » Wed May 02, 2018 9:21 pm

Hi .
My name is Claudio, I live in Buenos Aires and I sail in the De La Plata river.
I wanted to show you what I built last month, a wooden and epoxy hydrofoil with fiberglass and carbon fiber, all without vacuum. The core is plywood 11 mm except for the fuselage that is a handle of a large hammer.

Nice. Foil looks good. Certainly if you also consider that you did not have a fully equipped workshop with high end tools at your disposal.
Curious how it sails, tried it yet?

I am learning to ride foil. I only rode it once and I could do a few meters. It was my friends that they have been sailing for quite some time with Mosses and Slingshot, who said that it is slow and vibrates something, but that it is very good to learn . Flat with little speed
I did not even imagine the hard work that was to build it, but I liked doing it, it was worth it.I think the mast lacked carbon = hardness

Solid build. I like the side bolt through mast/fuse. Cunning.
Think about countersinging your bolts on the top plate. Then you wont piss your feet off when moving around the board.

Only thing i dont agree with is the rear wind on the bottom. That means all the force of the water is trying to rear the wing from the bolts. If the wing is on the top then the bolts secure the wing. The water pressure drives the wing into the fuse. Theres less stress on the bolts.

Not OP but I have built and ridden my own foil. If you can't foil (like me) then keep the front wing big and delta shaped. I foiled the top and flat bottom.... just to keep it simple.

I vac bagged by hand using a car break bleeder -- a hand vacuum pump -- and a cheap shower curtain. Not positive you really need to do this. Just a normal layout would be fine.

Choose a big board with at least 15cm of nose rocker. You'll touch down a lot, not crashing at this point is your fastest way to learn.

I built mine in my front room with no power tools. Just a hand saw, rasps, files, sand paper, epoxy and carbon fibre. If I can do it, you can!!

It is so much fun trying to make it and having to just figure stuff out as you go along (e.g. what front foil profile to use? )
