PPP body surfing hand planes produces the featured hand board in this video called the EdgeMX.
The Edge is a flexible linear planing bodysurfing handboard based on the triplane design. The PPP triplane designs are drawn from power boat configuration. For bodysurfers, this gives them it is important to have the design based on semi-displacement hulls so that the bodysurfing hand board would plane out & turn. This semi-displacement aspect can be better described as “linear planing” handboards:
The essential ingredients in designing the bodysurfing handboards were a mildly kicked nose, flat tail rocker, a “high-in-the-nose-to-lower-in-the-tail” rail line and “neutral handling”.
