Harken 7320.10 ESP Jib Reefing & Furling - Manual (Page 28)

28 ESP Unit 0, 1
Operation Furl
Unroll Sail
Uncleat furling line. Pull sheets to unfurl sail.
IMPORTANT! Keep tension on furling line when unrolling sail so line spools tightly on drum. Use a Harken ratchet block
or keep tension on the line by putting a single wrap of the furling line around a spare winch to provide drag on the line. This
is very important when wind is blowing over 10 knots. When line is tightly spooled on drum it furls in much easier.
Furl
To furl or reef, ease the jib sheets and pull furling line.
In very light breeze, place some tension on jib sheet to insure a tight furl.
In a stronger breeze, you must completely luff sail by totally slacking jib sheets before furling.
The furling line should pull readily. The amount of force required is related to amount of wind, but a unit should never
require use of a winch to furl. If the sail will not furl, or if furling requires a great deal of effort, there is a problem with
system. Consult Troubleshoot on page 32. Do not use a winch to force a system to turn. If you are certain that system
is operating properly you may use a winch to make furling easier.
