Reef
A sail may be partially furled before you resume sailing. This is
known as reefing.
Many sailors find it helpful to place marks on foot of sail so that
they can reef to a variety of predetermined jib sizes. This allows
marks to be placed on jib lead tracks or toe rail so that lead
block position can be changed to correspond to reefed jib.
Sails are generally reefed to balance boat and to reduce heeling
moment. Sails may also be reefed to improve visibility or to slow
boat while sailing in congested areas or entering or leaving harbor.
Secure Sail
When furling prior to leaving your boat in slip or on mooring, be sure that you get a tight furl
and continue furling system until sheets wrap around rolled sail two or three times. Some
people secure sail with shock cord or sail ties. Be sure to securely cleat furling line to a
standard horn cleat.
Be sure that mooring lines are not placed across furling line where they may cause chafe.
Operation
