Just finished my attempt at a homemade hydrofoil.
Big thanks to everyone that has posted their builds on this forum as well as on http://kitefoil.forumactif.org/
As you can see I have a little bit of inspiration from Carafino.
Construction: Made for excess materials I had laying around from various other projects, so a little random on construction.
Mast- Aluminum tube core with Birch wood bent over aluminum to form airfoil shape. Then covered and vacuum bagged. Lay-up starting at the core. 1/8" birch wood, 9oz carbon 45deg, 9oz carbon 0/90, 9oz carbon 45deg, 6oz fiberglass, 4oz fiberglass
Front wing- 1/2" plywood core, 1/8" foam (to help shape top part of airfoil), 2 layers 6oz fiberglass covering top and bottom.
Rear wing- divinycell core, covered top and bottom with 3 layers 0/90 6oz fiberglass, 2 layers 45 deg 6oz.
Fuse- (3) 1/4" thick Polpar glued together and covered in 6oz fiberglass.
Haven't had a chance to try it yet so can't give a ride report. Hopefully it works.
