Choosing a Staysail Furling System
Maximum LP
is determined by amount of line that can be wrapped on drum. If
your luff length is under 50' (15.25 m) but your LP is over 13

/

' (4 m), use 1852.
If your luff length is under 80' (24 m) but your LP is over 28' (8.5 m), use 1899.
Sail must be fitted with a special luff wire or rope designed for furling. This wire or rope must
transmit torque of furling unit to head of sail. Your sailmaker may need to shorten sail luff slightly to
accommodate length of drum and swivel. Some sailmakers add Velcro
®
to clew of sail to hold it in a
tight roll during storage.
A Staysail furler makes it easy to set or strike a staysail because sail goes up and down wrapped in
a tight roll. It's easy to test the effectiveness of a staysail in marginal conditions because the crew
can set or remove sail without leaving their normal positions —they simply roll or unroll sail.
A furler makes it easier to jibe. The staysail can be rolled and dropped on deck. After boat is jibed,
the halyard can be cleared and the sail reset.
A Harken staysail furling system is designed to be left attached to sail. Store staysail by “coiling"
loosely before bagging. We suggest sheets and furling lines of different colors to minimize
confusion when setting sail.

Sail Modifications
Determine Furling Line Length
Use amount shown in chart plus enough line to lead to where crew will be stationed. If you plan to
operate unit from close by add 5' (1.5 m) of line. If you plan to have a crew member furl from the
rail you may need to add 15' (4.5 m) of line or more.
