Full length Batten Installation
If you have ordered a Mast Furling Mainsail with Full Length
Battens, you will have received your battens in segments, which
need to be assembled. Simply identify the segments from the
batten labels and screw together using the just joiner.
Furl the sail
When the sail is new, it will be stiffer than your old sail. Please keep
some tension on the outhaul when you are first furling the sail, to
train the patches to accept the furl. Take note to see if there are
any excessive wear points and that the battens are entering the
mast evenly and smoothly.
Leech Line
Your new Mast Furling Mainsail includes and Around the Clew
Leech Line. The leech line is not a sail shape control but an
essential tool to prevent leech flutter. The leech line will have a
purchase system and Velcro closure above the clew and a cleat
with in front of the clew. Your sail will either have micro-blocks or
a tunnel to direct the leech line around the clew. Use the leech line
to prevent leech flutter in higher wind speeds and when reefed.
Excessive leech flutters can cause serious sail damage.
Sail Shape Control
You can control the depth and position of draft in your new
mainsail by adjusting the halyard tension. A tighter halyard will
move the draft position further forward and result in a flatter sail.
When your sail is new, pull the halyard up just enough to remove
any horizontal creases along the luff. In stronger breeze you will
need more halyard tension.
