Harken 7413.10 MKIV Jib Reefing & Furling built after Feb. 2009 - Manual (Page 33)

Furl and Reef
To furl or reef, ease the jib sheets and pull
furling line.
In very light air, it might be necessary to place
some tension on jib sheet to insure a tight furl.
To furl in a breeze, ease sheets gradually and
pull furling line in steps until sail is furled or reefed.
The furling line should pull readily. Depending upon
wind strength, larger furlers may require use of a
winch to furl. If sail will not furl, or if furling requires
a great deal of effort, there is a problem with system.
Consult the Troubleshooting Guide on page 39. Do not use a winch to force a system to turn. If you are certain that the system is
operating properly, you may use a winch to make furling easier.
Raise Sails
1) Install prefeeder by securely tying end of line to a deck fitting or to toggle
below furler so it is 610 mm (2') below feeder.
2) Shackle tack of sail to drum. Install shackle so screw-pin head is on same
side as sun cover.
3) Secure genoa sheets to clew of sail.
4) Attach genoa halyard to halyard swivel.
5) Pass luff tape through prefeeder and feeder into foil groove.
6) Attach head of sail or pendant at head of sail to halyard swivel.
7) Hoist sail.
8) Furl sail to check for possible halyard wraps. See pages 29 - 30.
9) See if sail will furl completely and still leave two wraps of line on spool
and two wraps of sheets around sail. See “Secure Sail” on page 36.
Tip: New sails are often stiff and may hang up on prefeeder during
raising. Do not force sail when it hangs up. Lower and remove
twist. Sails "break in" with use and will become easier to raise.
Storm Sails
Most people will use one multi-purpose genoa for all their sailing, but it is not good seamanship to go offshore without storm sails.
Heavy-air working jibs and storm sails should be used with your unit. These sails need to have luff tape added to allow them to be
raised in headstay foils.
These sails will generally require pendants to ensure that halyard swivel is properly positioned at top of headstay.
See page 29.
Remember that heavy-air working jibs and storm jibs may be reefed and furled like any other sail.

Operation Sail: Raise/Storm/Reef
WARNING! Using a winch to furl when the halyard is wrapped may cause the headstay to fail, resulting in an accident.
