Those of you who are familiar with FCS fins might be scratching your head on this board. The sides are futures, but the trailer is only 1 (instead of two) FCS box.
I liked the idea of the Shark Tooth trailer:
but wanted adjustability. So we take a larger fin and cut it down to the size and shape, PLUS cut a single notch to fit in the single FCS box. By cutting the notch forward or backwards from center we can adjust the placement of the fin. Cool, huh?
