The Jarvis is meant to be ridden more skate, not like a wakeboard. There's a balance between edge and fin. Twisting the hips upwind will find you riding further upwind with less resistance due to the extra fins - which can be mixed and matched for more versatility of the rider or conditions.
The board is very well received and Doyle, the shaper of the boards, is very well known. Most people love their skate series slingshots but you gotta learn to ride any board.
