Secure Sail
When furling the sail completely, make sure sheets and furling line are
secured. Check amount of line on the spool compared to the furled sail
before using the system.
A furled sail must have:
a. Two to three wraps of jib sheet wrapped around sail.
b. Two wraps minimum of line wound on spool.
c. Furling line securely cleated.
d. Jibsheets securely wrapped on winch and held in self-tailing jaws.
Furl at dock with tension on sheets to duplicate furling in high wind.
Remember sails furled in light wind and left loosely secured can be a problem
if wind increases.
IMPORTANT! Remove sail from furler if extreme winds are predicted,
especially if boat is left unattended.
IMPORTANT! Check all points above—a, b, c, and d—when leaving boat
to avoid damage to furler or boat. A loosely rolled sail can catch wind in
a storm. Sheets or furling lines can loosen as winds increase and allow
furler to unroll.
Be sure mooring lines are not placed across furling line where they may
cause chafe.
IMPORTANT! If no wraps of line are on spool, the line deadend can break
the spool when the boat motors through waves.
If you want to:
Add more wraps of
jibsheet on furled sail. Untie jib sheets and keep sail
completely rolled. Secure with
sail tie.
Turn spool to unroll a
couple of wraps of line.
Retie sheets.
Add more wraps of line
on spool.
Turn spool to add a
couple of wraps of line.
Reef
A sail may be partially furled before you resume sailing.
This is known as reefing.
Tip: Place marks on foot of sail for a variety of reefed jib
sizes. Place marks on jib lead track so lead block position
matches reefed jib.
Reef sails to balance boat and reduce heel.
Tip: Reef sails to improve visibility or to slow boat while
sailing in congested areas, or while entering or leaving
harbors.
