Tuning Guide for the 2000 Ezzy Duo and Duo Plus
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.

). 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.
