Gaastra Sails
Technical Features1 Drop Foot The Manic and Poison wavesails have a ‘drop foot’ feature
that is intended to bring the
sail luff closest to the deck at
the tack. The tack pulley should
be close to the cleat base as is
reasonable, usually about 1cm.

Batten Tension System Use the key provided. Adjust the stainlesssteel screw as much as necessary to removewrinkles along the pockets and createsmooth tension.
Our goal is to develop sails, which suitthe broadest range of sailors. The
compact outlines use short luff lengths
and efficient tip configurations for
maximum efficiency. Tight rotations,
control in flight, and rapid redirection
are the result. Low sail weight,
minimizing rig weight with use of
recommended masts and booms, keeps
total rig weight down, and improves
stability and handling.

Tuning for Performance When correctly rigged on the
beach, Gaastra
Wave sails will
show soft looseness in the
upper leech, progressing to
less and less. Do not use
negative outhaul. Draft should
feel low and forward, with a
balanced, soft feel. For those
using other than Fiberspar mast
bases, the setting printed on
the sail can be measured as the
distance from the bottom of
the mast, to the lower front
corner of the sail pulley.Fine tune outhaul around yourpower requirements. More
outhaul is less power and more
control. Less outhaul is more
power and less control. You
should have solid tension on
the clew, even at minimum
outhaul. This ensures good
leech tension and stability. Pulley Tack Fitting
Set the basemeasurement
and insert base
into mast.
Careful attention to the order and
direction of turns in the line will give you
the best advantage and lowest friction
when downhauling. Follow the diagram: Chafe Protector Adjustable Head System This durablewebbingcover has
been packed
in with the
RiggingGuide and sticker pack. It is to
prevent abrasion of the
adjustable head webbing when
using longer masts thanrecommended. Install as shownin the illustration. This is
provided to
allow the use
of longer
than recom-
mendedmasts. When using the mast ofthe correct length, pull the tipplug as low as it will go in the
head of the sail. This will help
protect the webbing from
chafe, and guarantee the best
relationship between the sail
and the bend of the mast. Go from the deadend on the cleat base
to the same side of
the forward pulley
wheel.Go next to theopposite cleat base
wheel (but not the
one with the cleat).
Put the rope inclosest to the mast.Then go back to the
sail pulley that is
farthest from the
mast, inserting on
the same side. This
will make a clean
loop, with no twist.Now feed the ropeinto the cleat basewheel closest to thedead end, inserting
it towards the mast.
Then go back to the
sail pulley, inserting
in the middle wheel,back to the cleatbase and the cleat.

Rigging Instructions 2 3 Set the boom and base at thedimensions printed on the trim guide
located near the tack. Should you be using
a mast, which is 30cm longer, you will need
to adjust the head extension. Check that all the battens are fullyinserted into their pockets and
at least lightly tensioned. 1 Inserting the mast into the luff sleeveis easy on sails without cams. We suggest
folding up the tack fairing to ease mast
insertion. Before de-rigging, clear the tack
fairing from the mast base rings and other
rig components. 4 5 Insert the mast into the sleeve, workingthe sail down a bit at a time. Make sure
the mast ferrule joint is fully connected or
this can result in damage or breakage of
the mast Check the mast tip plug for fit in thetop of the mast.
PRO-TRICK ONLY ... at armslength, worksbest for me! 6 9 Thread the downhaul line and partiallytension the luff. Re-tension the battens as necessary. 8 Downhaul to within one centimeter ofthe cleat base. Fine tune around this
position. Always try to rig so the tack fitting
will be as close as possible to the back of
the mast. This improves balance and
handling. 7 Adjust the boom to the recommendeddimensions. Attach the boom to the mast,
and leave sufficient space to allow for
tensioning. The end of the boom should
be within two centimeters of the clew. For
best results, use a tape measure to ensure
accuracy and repeatability.
No.8 Lock boom into position.Use the spacer/shim ... if using a RDM mast. No.9 ... FULLY downhaul sail.
Experiment with your tuning Experiment to find trim settings
that work for you and your
particular equipment.
Generally, most Gaastra sails
work the best when tuned with
sufficient downhaul to make
the upper leech panels loose,
and getting progressively
tighter as you go down. Tuning
for body weight or conditions
revolves more around outhaul
settings. For lighter winds use
less outhaul, and increase
tension to improve control.When
sailing, you want afirm, straight leech as part of
a properly twisted foil shape.
The draft point of the sail
should be forward, with power
low and a balanced, soft feel.
No.10 Tie off the boom,correctly thread. No.11 Set boom to length and pullouthaul rope to tension sail.
Sail Maintenance Do not leave your sail exposed to
strong direct sunlight. Whenever
possible, lay it in the shade, orstore vertically. Light penetration at ninety
degrees is most damaging.Do not use solvents or chemicalsto clean sails. Use fresh water and
mild soap. Rinsing the sail withfresh water and shade drying before
storage will add to longevity.
If you have holes ortears, have them
repaired by a qualifiedsailmaker to prevent further
damage. This is especially
important if the damage is in
the monofilm panels.Dry your sail, roll it,strap-on, and store it
in the bag. Do notallow it to be crushed or badly
creased under other heavy
objects.There is no need to de-tensionthe battens except for long-
term storage or travel. VISUAL CHECK
No.12
1234 Looking at the leech, thereshould be looseness between
the battens, the most between
#1 and #2, less between #2
and #3.Looking at the luff pocket, itshould be tight at the second
batten.Batten #3 should just begin toloosen, and both #4 and the
foot batten should be free to
rotate around the mast. You
will need sufficient outhaul to
make this the best.For questions and technical information regarding tuning, you may use ourforums at
