KM is short for the Hawaiian word Kai Mana or "Ocean Power". The KM Carbon X SUP is the pinnacle of performance Stand up Paddle Surfing. It starts with the progressive shape of less volume in the nose area, a flat deck, and a quick response swallow tail.  Then this shape uses a thinner more sensitive rail while finishing up with a double concave contoured bottom.  In the glassing KM wraps top and bottom with Carbon fiber to bring you a stronger, lighter finished product.  The Carbon X comes with 4 Future boxes and a 10" center fin box giving you as many fin configurations as you can imagine.  This board includes 3 fins with purchase.
