Hi Guys,
What is it with people talking about volume in kitesurf boards? Volume makes absolutely NO difference in a kite surfboard. On a normal paddle surfboard, volume is quite critical as it floats you and determined how far out of the water you sit when paddling for a wave. If you sit higher in the water you paddle faster because less of you is under water, the wave needs less energy to get you onto the plane on take-off.
On a kite surfboard, where you are always planing, the volume is irellevent as the volume is all above the planing surface (bottom) of the board. If anything, excessive volume only makes water starting more difficult as you can't sink the rail to get the board on edge if you use foot straps.
The critical thing on a kite surfboard is planing area, rail shape and rocker. Width in the tail gives early or low speed planing, so makes for holding more speed and not sinking the tail in mushy waves. This will translate to easier linking of turns. Wider boards are better for Perth conditions. Narrow tails only work well when you are more powered up or have big enough waves to use the wave and not rely solely on the wave shape.
A perfect example is the Spleene surfboards that have virtually NO volume due to their snowboard style construction, and they surf brilliantly.
Surfboards made of Polyester resin will develop heel dents, these are not good to have, they are a sign of the core being crushed which weakens the board. There is no doubt that a poly board feels and surfs a tad better than an epoxy board due to the flex, but they are not going to last if you ride hard. An good epoxy board is tough, especially the new North boards as they use cork under foot so the deck can depress and spring back into original shape, this maintains the structural integrity of the core which is the foundation of the strength of the board.
Rant over!
