Turbinator Surfboard
Surfboard shape creates vortices for stability

Instead of a fin or group of fins (skeg's) the underside of a surfboard could be shaped to produce two long vortices that would provide stability through choppy water. Once moving, it would make steering somewhat harder, but the bigger the wave (faster the speed of the surfboard) the more solid the ride would become.

Sensation: Like Poseidon is holding your fin and pushing you through the water.

As for maneuverability, once the vortices are broken, sideways movement would be extremely simple. Below a certain speed the vortices would not be generated, but the underside would provide some steering.

Think Manta wings turned downward.

       Ah. I only got it after the Manta comment.
