The HIHP is the board Harley won both of his world titles on. Continual rocker allows the HIHP to fit seamlessly in hollow waves and be adjusted from anywhere on the board, while a progressive rail and rocker combination facilitates both aggressive turns off the tail and extended noserides.

A flat bottom contour upfront supports tip time and superior planing tight in the curl, while a slight convex through the middle of the board allows the board to transition from rail to rail quickly and efficiently. A spiral vee with double concave gives way to a flat bottom through the tail, allowing for powerful turns off the back third of the board. The HIHP is typically ridden as a 2+1, but quad boxes have also been added for larger, more powerful surf when conditions call for extended turns at speed. This is an all-around performance longboard designed for hollow waves and beach breaks, but capable of trimming its way down points as well.
