Developed and designed by: The Point-7 Black Team. A
team of professional sailors and designers who have proved themselves
by designing the winning sail for the World Champion in the PWA Slalom
Development Target: The target is done by comparing
the differences between the AC-K and AC-1. Reducing the differences in
terms of performance, keeping in mind that it needs to stay a
user-friendly sail especially on the water, when rotating the sail after
the jibe, and keeping a high speed with a lighter feel in the hands.
All this whilst still allowing the rider to save more energy, allowing
you to stay on the water all day.
Outline: A real slalom sail figure. The
base allows you to close the gap on your slalom or freerace board as
with any racing sail. A negative leach to allow extra speed and
acceleration whilst keeping a light feeling on the back hand. The top of
the sail has a smaller head for more stability in stronger wind. The
right mix between low and high aspect ratio duties.
Battens: 7 tubular battens to follow the
pure slalom foil profile from the sail. Each batten exactly copies the
set-up of our AC-One racing sail.
Eyelets: The choice to have two eyelets.
The lower eyelet to create more opening of the lower leech to increase
control in stronger wind, and the higher eyelet to increase power and
acceleration. We do advise the upper eyelet, unless you are a
Profile: For 2018 we have brought an
increase of profile in the front to increase the drive for earlier
planing and acceleration in lighter winds. The drive is fundamental for
carving the board better in the jibes. A deep front profile allows
stability in stronger wind, therefore increasing comfort and control.
Foil: The front profile, due to its deeper
profile set by the 3 cams, allows an existing smooth and stable entry
for the wind to sit comfortable, and give the stability and pressure
which transforms into drive and power. The wind swiftly moves to give
power exactly where the stance of our body is comfortably centered on
the board, and releases quickly and smoothly through the back of the
sail, to allow light back hand presuure for pushing on the fin. As the
wind increases, the sail will automatically self-adjust its power,
thanks to the S-Shaping, along the whole middle upper leach opening.
Cut out: A medium size cut-out is
introduced to allow a comfortable S-shaping release: Not as big as a
race sail which would lose power in light-wind, but big enough to have
the board to rail comfortably, and allow the wind and speed to increase
through the foil as the wind picks up. This results in giving us the
chance to increase our water performance without having to act with
power and energy. The shape of the cut out comfortably welcomes the
back end of the boom.
Body Material: Mostly assembled by the 4mil Anti
UV-Black Laminate. Highly responsive and reactive for world champion
performance. 5mil Anti UV-Black X-ply base panel for protection from
accidents. Clear monofilm window for perfect vision through the sail.
X-ply batten pockets for lighter weight and reflex.
Cams: Different size cams are placed in the sail to
determine the light pressure and fast rotation on the higher cam,
stability, profile and power on the lower cams.
Rigging: The AC-K needs to have the mast inserted on
top of the cams. After pulling downhaul to 15cm of its final setting
you can either put on the boom, and later slide in the cams before
putting the final downhaul on, or place the cams on with the right
technique, pulling on the full downhaul, and later putting the boom on.

It requires a reasonable amount of force to counter its moderate luff
curve and be guided by the visual aid in the second top panel. It rigs
rdm masts on the 5.2 and 5.8 size and sdm mast on the other sizes.
Playing with the outhaul will boost up power or increase control.
Tighten the lower 2 battens and the top batten, but just remove wrinkles
on the other battens, without overtightening them.
