GLOBAL COMPACT WAVE DESIGN
The brand new Simmer Style Cortex will change the way you look at an
average day. Cortex features extremely short length and a narrow outline
with diamond tail configuration. Combined with a very fast rocker,
Cortex is extremely agile and tight turning. The parallel outline and
smooth rail flow keep you in complete control during quick rail to rail
transitions. Optimized for both sideshore and onshore real world
conditions Cortex delivers snappy turns and quick reactions in the
traditional windswell 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 freewave board.
When Kai Katchadourian needed a dedicated board for Peahi, aka Jaws, the
controlled but still turny freewave shape was chosen to form the basis
for the unparalleled speed and control that such a board requires.
Freewave 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 Peahi
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.
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 slotboxes for quad fin, tri fin or twin fin setup.
Standard fin setup // TRI
tri fin setup will provide early planing, great upwind tracking and
ease of sailing while still providing a insanely tight turning radius.
On the wave, this setup will give you the best possible projection and
drive in turns, assisting the sailor in keep speed through the bottom
turn, even in less powerful waves. Versatility and snappiess with a user
friendly feeling are the main characteristics of this setup.
Alternative fin setup // QUAD
with a quad fin setup, the Cortex gets more planted and controlled at
higher wave riding speeds. The power of the fin cluster acts further
forward, which drives the front rail into the water and gives the board
added control in draws out turns. At the same time, the shorter depth of
the two rear fins makes it easer to set the rail at high speeds which
means that the board feels more responsive in fast sideshore or cross
Alternative fin setup // TWIN
only two fins, drag is lower and the fin power acts further back on the
board. This lifts the nose of the board which in a straight line adds
further speed and gives more looseness and quicker reactions in turns.
The combination of twin fin and the fast tail rocker provides great
ability to set up the top turn either for slashy release or solid power
- Cortex combines fast rocker with a progressive v flow for good control.
- Parallel outline and smooth rails gives the rider good control and speed in botom turns
- Awesome performer for real world conditions where it delivers snappy turns and quick reactions.
- Outline is shortened by using a diamond tail, which allows for a even tighter turning radius, and ultra quick rail-to-rail performance.
- Quick accelerating v-angle frees the board up for enhanced shorter turns and ultra quick rail-to-rail performance.
- Cortex comes with 5 carbon slotboxes which gives you a large spectrum for trim options.
