The Cortex will totally change the way you look at an average day. With an extremely short length and a narrow outline with diamond tail configuration, it delivers the best onshore conditions. Combined with a very fast rocker, Cortex is extremely agile and tight turning even when the surf is on. The parallel outline and smooth rail flow keep you in complete control during quick rail to rail transitions. Optimized for both side shore and onshore real world conditions Cortex delivers snappy turns and quick reactions in the traditional winds well zones and can also be tuned to slice and dice in more side offshore down the line environments. The Cortex may be a new school short board, but it has a long history. The rocker, spiral v and concave profile has its roots in the original Simmer Free wave board.
When Kai Katchadourian needed a dedicated board for Peahi, aka Jaws, the controlled but still turny free wave shape was chosen to form the basis for the control that such a board requires. Free wave was a great hit and the dependable bottom shape has since been used in a variety of shapes in our prototype process. The most exciting of those designs became Cortex where the fast and controlled bottom, based on a progressive rocker flow and double concave v bottom, is combined with a parallell outline and smooth rails. This creates a board that is an awesome performer for real world conditions where it delivers snappy turns and quick reactions. Kai’s original spiral V-bottom heritage still shines through on rail stability and general control through rough conditions, yet Cortex and it’s short length and aggressive stance has changed the game forever in how you attack a wave.
The mechanics of this shape is a combination of several design choices; The fast and controlled bottom combined with a sleek, low entry outline provides excellent flow, especially in slower waves. The squared off nose allows the board to fit in tighter parts of shorter trough waves while still allowing a long enough rail line for solid full rail carves. The shortened diamond tail and accelerated v-angle frees the board up quickly for enhanced shorter turns and ultra quick rail-to-rail performance. The parallell outline converges into the tail area under foot providing ample lift for early planing and lots of pop for aerials and jumps. Cortex can easily adapt to different turning angles. With the stance set as far back as possible, the inner angled rear section adds grip in top turns, and extra torque in tight bottom turns. In addition, a pulled back mast track gives the rider the choice of freeing up the board even more by placing the mast in the rear of the box, or to stabilize it for longer turns or jump oriented sailing by placing the mast foot slightly further forward.Cortex comes standard with five carbon slot boxes for quad fin, tri fin or twin fin setup.
