I'm at the very earliest stage of learning to kitesurf and am aiming to build my own boards as I progress. So far I've had one session on this board where I managed to stay upright for about a 30 seconds over the course of three hours, I did have to learn to fly a new kite in that time as well.
The board is 9mm ply, epoxy coated. Design and construction basically follow the concepts from zeroprestige.org. The fins are the only place I used any glass. I steam-ironed some rocker into it, but it ended up pretty flat. I weigh 70-75kg so I suppose this is a pretty big board. I felt underpowered with an 11 square metre kite in 15 knots.
I doubt the curves really do anything besides look intersting, but I just couldn't bring myself to leave it rectangular.
Looking forward to some wind so I can try it again.
I would appreciate any comments/critique on this board or suggestions for my next one.
