The board was originally designed for Martin Potter based on boards from his twin fin days (The Pottz Flyer). A fuller outline and flatter rocker but more refined for high performance and drive and easy glide over those flat sections. More foam under your chest allows for easy paddling. A nice 50/50 rail makes this board very forgiving. A very slight rolled vee leading to a heavy vee between the fins and running back to a slight vee off the tail.
