SAIL TUNING
Rigging:
1) Slide the mast through the luff sleeve. Note: slide
the mast above the cams (do not attach the cams to the
mast yet).
slide the mast above the cams.
2) Attach the mast extension
and thread the line through
the cleat. Do not tension the downhaul yet, just cleat the
line off.
3) Attach the front of the boom to the mast and
outhaul the sail to the boom length that is printed on
the sail. The suggested boom length is measured from
the clew to the front of the mast at the center of the boom
cutout.
4) Attach the cams to the mast by pushing down on the
batten with the palm of your hand, approximately 12" (30
cm) from the luff sleeve, and snap the cam onto the mast
with your other hand.
If the cam is difficult to put onto the mast,
check that the batten tension webbing is
loosened until the
Velcro
™
touches the

5) Downhaul the sail until the leech goes loose between battens #2 and #3. Use the printed marks as a
reference. For light wind, the looseness should extend to mark #1. For medium wind the looseness should extend to
mark #2 and for strong wind, the looseness should extend to mark #3. At the head of the sail, batten #1 is designed
to always be very loose. See diagram below:
Quick Tip-It is possible to over-
tension the cam batten, which will cause the cam not to rotate. A quick check of this can be
done by holding the sail up on land and pumping the sail from both sides of the boom. The cam should rotate smoothly; if it
doesn't, decrease a little batten tension.
loosened until the
Velcro
™
touches the
buckle. This will allow the cam to slide
further from the mast and will make it
easier to get the cam onto the mast. Also,
make sure the sail is outhauled flat
before attempting to snap the cams onto
the mast.
Opening the zipper will make it easier to
snap the cam onto the mast. But, to
avoid damaging the zipper, be sure to
close the zipper againbefore tensioning
the cam batten.
The amount of downhaul tension will vary for different
wind conditions: A high-wind setting requires more
downhaul tension to loosen the upper leech and give
more twist. In lighter wind, the sail needs less
downhaul for a tighter leech and better low-
end power.
For the correct sail rake, the foot edge of the tack
should be no more than 4 inches (10 cm) above the
deck of the board. Always keep your base extension at
its shortest possible setting. If there is not enough
space for downhauling
and you have mast extending
from the top, use the adjustable top to raise the sail up
on the mast rather than extend your base.
6) Now, tension the two camber battens by pulling
on the batten strap while pushing the palm of your other
hand against the batten end-cap. When the camber
battens are correctly tensioned, the sleeve directly in
front of the cam should be tight.

De-Rigging: (Following this de-rigging sequence will prolong the life of your sail and avoid possible sail damage.)
1) Release the camber batten tension (push the release lever located on the center of the buckle) and
undo the tack-strap.
2) Unfasten the mastpad Velcro™.
3) Release the downhaul.
4) Snap the cams off the mast.
5) Release outhaul and remove the boom.
6) Slide mast out of luff sleeve without creasing the sail.
9) Check that the camber is not over-rotated. Over rotation will fatigue the cam and lead to possible
breakage. If the cam is over-rotated, you need more downhaul.
Cam is not over-rotated, downhaul is correct. Cam is over-rotated, need more downhaul.
10). Wrap the tack-strap webbing around the bottom of the mast base. The tack-
strap should be tensioned at
least until the edge of the foot is tight. High tack-strap tension is desirable in all wind conditions.
The tack strap can
not be over tensioned; more tension in stronger wind puts the center-of-effort lower, giving the sail more control; in
light wind, tensinoing the tack strap makes the foot deeper and tightens the lower leech creating better low-end
power.
11). Secure the mast pad by wrapping the Velcro™around the mast then over the mast pad.
7) Check that batten tension on the screw-batten tensioners is correct.
YOUR BATTEN TENSIONERS HAVE BEEN SET AT THE FACTORY AND
SHOULD ONLY NEED SLIGHT ADJUSTING. When correctly tensioned, there
should be no wrinkles running across the batten pockets. If the battens do need
adjusting, use the screwdriver key that is stored at the tack of your sail and tighten
the battens until the wrinkles through the batten pocket disappear. WARNING:
OVER-TENSIONING THE BATTENS COULD DAMAGE THE SAIL.
8) Release the outhaul completely and re-set it
according to the wind strength you will be sailing in. For
light wind, use about 2.0cm (3/4") of positive outhaul
tension. For high wind outhaul up to 5.0cm (2") of positive
outhaul tension.

7) Roll sail beginning from the head, and tuck in the mast pad horizontally.
8) Insert the sail into the sail bag with the sleeve-end first.
Sail Care:
Trouble-Shooting:
Sunlight:
Sunlight will break down all sailcloth in a relatively short time (300 hours of direct sunlight).
Don't dry off your sails in the sun! It is better tot dry them in the shade, or to roll up wet.
Creasing:
Creasing damages sail cloth. When rigging and de-rigging, try not to crease your sail or let it
flap in the wind.
Sand:
Sand will scratch the sailcloth film and can clog the batten tensioners. Try to roll your sail
sand-free.
Cleaning:
Use a mild soap and water with a rag to clean your sail. Harsh solvents may damage the sail
cloth.
Contrary to what most people think, you do not need to fresh-water rinse your sail.
Storage:
It will not damage your sail to store it with the battens fully tensioned.
If storing your rolled sail vertically, make sure the sleeve-end is supporting the weight. This
prevents the clew from getting damaged.
Problem: Possible Solution:
Camber is difficult to get on
the mast:
1) Make sure the batten tensioner is completely released while
snapping cam on.
2) Make sure the sail has no downhaul tension and is outhauled fully
before snapping cam on.
Camber does not flip: 1) Camber batten too tight, release a little batten tension.
2) Cam is under-rotated, need less downhaul.
Camber comes off of mast: 1) Camber is over-bending, need more downhaul. 2) Mast diameter is larger than normal, lengthen the webbing straps
on the cam.

Sail feels heavy: 1) Leech is too tight, try more downhaul.
Sail feels too powerful: 1) Sail is too deep, try more outhaul and downhaul.
2) Mast is too stiff, check that you are using the correct mast.
Sail lacks power: 1) Sail is too flat, try less outhaul and less downhaul.
2) Mast is too soft, check that you are using the correct mast
