I love the surf band in the video JL.
I'm impressed with the design elements in the Module. As Rock pointed out, the step/wing and fin combination give a true pivot point. The wings on the rails of some wakesurfers don't align with the fins and so, IMO, mute the effectiveness of that wing. With this design, the step IS the end of the fin and will provide that release point.
In terms of drive, as Scott brings up, the depth of the fin isn't what creates drive, instead the base is mostly responsible for that. If you visualise two yardsticks attached as fins to the bottom of a board, a 1 inch base with 36 inch depth won't provide significant drive, perhaps if sturdy enough, they would offer directional stability - they would reduce the boards ability to tail slide (maybe
). In this design, the fin base is quite long. I think I counted 9 checkerboard patterns in one of the pictures above. In theory, that should offer more than adequate drive, although I'd also bet a skatey feel on demand. Also, the relatively parallel outline at the back, in order to accomodate the fins/rails (avoid toe OUT) should aid with down-the-line speed. To me the combination of the various design elements in this board is amazing.
I'm looking forward to a ride video.
