that it opens up a whole new challenge for sail design. The fundamentals of foiling are simply different than normal windsurfing, which is why the Hydra looks nothing like a normal windsurfing sail.
Overall, we had 5 goals when designing the Hydra and we are happy to say that the design accomplishes each one. The goals are:
1) Must be more efficient than a normal sail
2) Must be less sensitive to gusts than a normal sail
3) Must have early power to get up and going but also controllable when flying
4) Must be able to de-power easily
5) Must be super light weight
