PPP Handboards uses Displacement Hull design. Our influence came from George Greenough and his spoon design and fins. From that era many shapers started making boards with those kinds of designs, including Paul Gross of 4th Gear Flyer and ourselves at PPP bodysurfing handboards.
The displacement hull is inspired from boat design, the hull ( the belly vee on the nose of the board) is displacing/pushing water to clean and prepare the surface to the flat bottom shape for perfect glide, and more speed.
PPP bodysurfing handboards use a tri-plane displacement hull (three different planning surfaces) this combination pushes water and once the displaced water passes by the tail it creates elevation, which is the typical feeling of a planning hull. “Flying on the water”!! The rails are 50/50 or mostly inverse (60% bottom 40% top) so as to maximise the opportunity in the hollow of the wave.
The belly inverse rail of the PPP bodysurfing handboard lets the rail slice through the face of the wave because of the shape of the rail. When surfboards dip the rail into the wave face it can stall the speed … whereas PPP Edge bodysurfing handboards slice through the face of the wave because of the shape of the rail. The shape of our rails improves the handboard’s bottom planning.
The planning of our Edge bodysurfing handboard results in less contact with water, in order to achieve the goal of having the least amount of friction as possible with water.
Less friction with water results in maximum speed possible!
The great thing with hull displacement is that once the hull is up on the plane, the wave and the handboard will move in synch with the board and the wave itself, on a natural wave avenue.
The Rocker is very flat, especially the tail rocker, offering complexities or simplicity … whichever you choose to explore, but it's one of the best tools to get speed. The bottom shape is flat from the tail until the widest point and then turns to a big belly vee, the famous "hull".
One other particularity of the displacement hull is the S-Deck. If you look at the rocker of the board, you can see on the top this insightful design which looks like an S. This lightens the handboard, because you'll bodysurf only on one focal point: the widest point which is forward on the handboard, you need only volume to support your hands.
The S-deck will make the perfect balance. Due to the position of the hands to the middle of the planing surface, the fin is forward, so you'll have the control/drive of the board while staying on the maximum plane of the board.
The fin has a really serious role. This kind of design provides an option to make your bottom turn in two steps. First time you'll take off and go straight, and then you'll start making a big turn and push on the heel of your hand, then the flex will react and project / propel you into the pocket of the wave where all the wave's energy is. This feeling is an amazing feeling and exclusive to Displacement Hulls designs.
The Displacement Hull has layers of complexity … the more you challenge the handboard the more it will ask for more …. Alternatively you can take the easy route to ride …. A handboard for the fun of bodysurfing …. Or for the adventuresome J
Once you handboard into the wave, you'll have nothing to do, the board will do the job by itself and the less you do the more speed you get. The more you bodysurf with displacement hulls, you'll need a few waves or sessions to understand the extremities that you can push these bodysurfing handboards.
But for me it's the best feeling ever, and it's the best design about.
The feeling is hard to describe, but it makes you bodysurf with style, and glide with 100% of the wave's energy. You can feel the "smooth" gliding pulling you closer to nature as you push yourself to the outer most limits.
