EZZY SAILS Duo 1999 Quick start guide

Rigging and sail tuning for the 1999 Ezzy Duo
1999 Ezzy Duo
Rigging & Fine Tuning
Guide
These tuning tips will make your sail work the way
I designed it to. Use them to find your own perfect
settings. Be sure to rig and de-rig in the same
order as outlined in this guide; you not only get on
the water faster, but you will also extend the life of
your sail.
See you on the water,
David Ezzy
Rigging:
Slide the mast through the luff sleeve. Note: slide the mast above the cams (do not attach
the cams to the mast yet).
Attach the mast extension and thread the line through the cleat. Do not tension the
downhaul yet, just cleat the line off.
Attach the boom and outhaul to the boom length that is printed on the sail.
Quick Tip -The boom length is the distance from the clew to the front of the mast at the
center of the boom cutout.
Attach the cams to the mast by pushing down on the batten with the palm of your hand,
approximately 12" (30cm) from the luff sleeve, and snap the cam onto the mast with your
other hand,

Quick Tip
-
If the cam is difficult to put onto the mast, check that the batten tension
webbing is 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 cam onto the mast.
Quick Tip -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 again BEFORE tensioning the cam
batten
Downhaul the sail until the leech goes loose between battens #2 and #3. Use the sail
logo that is printed on the sail as a reference. The front and back ends of the logo coincide
with the maximum and minimum downhaul settings (see diagram below)
Quick Tip -The amount of downhaul tension will vary for different wind conditions: A high-wind
setting requires more downhaul tension to loosen the leech and give more twist. For lighter
wind, the sail will perform better with less downhaul. This gives the sail a tighter leech and
better low-end power.
Quick Tip -For the correct sail rake, the foot edge of the tack should be approximately 4
inches (10cm) 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.
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.

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.
Check that the batten tension on the screw-batten tensioners is correct. When
correctly tensioned, there should be no wrinkles running across the batten pockets.
NOTE: YOUR SCREW BATTEN TENSIONERS HAVE BEEN SET AT THE FACTORY AND
SHOULD NOT NEED ADJUSTING. If the battens do not need adjusting, use the Allen key
that is stored at the tack of your sail and tighten the battens until the wrinkles throughout the
batten pocket disappear. WARNING: OVER-TENSIONING THE BATTEN WILL DAMAGE
THE SAIL.
Release the sail completely and re-set it according to the wind strength you will be
sailing in. For light wind, use with neutral outhaul tension and for high wind use
between 1.0cm (3/8") to 2.0cm (3/4") of positive outhaul tension.
Quick Tip -We recommend using the lower clew grommet for most sailors, however, if you
attach your boom at the top of the boom cut-out, the upper grommet is recommended.
Check that the camber is not over-rotated. Over-rotation will fatigue the cam and the
batten and lead to possible breakage. If the cam is over-rotated, you 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.
Quick Tip -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, tensioning the tack-strap
makes the foot deeper and tightens the lower leech creating better low
-
end power.

De-Rigging:
Quick Tip -To increase the life of your sail, it is recommended that you de-rig in the following order:
Release the camber batten tension (push the release lever located on the center of
the buckle) and undo the tack-strap.
Release downhaul.
Snap cams off of mast
Release outhaul and remove boom.
Slide mast out of luff sleeve without creasing sail.
Roll sail from the top and use the strap we've provided to tie the sail.
Insert the sail into the sail bag with the sleeve-end first.
Sail Care:
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.
The vinyl window can be cleaned by washing with fresh-water and polishing with dry towel.
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.
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.
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.
