Preassembly Rigging Parts Check/Tools

1. Harken toggle assembly required. Sold separately.

2. Mating turnbuckle components must be purchased separately.

3. Headstay may require cutting and shortening to fit Harken
toggle. Headstay may remain uncut by replacing lower stud
of turnbuckle with stud/eye thus eliminating extra toggle.

4. Rod rigging requires Harken rod adapter stud.

WARNING! Headstay condition should be
checked by a professional rigger before
reusing. Wire that is old or damaged
may break suddenly causing an accident,
damage to your vessel, personal injury,
or death. See www.harken.com for
additional safety information.

5. Order Harken 7404 Lead Block Kit and one additional 7403 if necessary. Fits 1" (25 mm) stanchions.

Preassembly Sailmaker's Instructions

Luff Length
Note offsets above and below sail.

C

A shorter luff may be required if a halyard restrainer is necessary
(page 23) or a toggle or long toggle assembly is used to raise drum.

If luff of sail is not long enough to put halyard swivel near top of head-

B

stay foil, make sure a pendant must be added. (See page 22).

A

Tack Setback

Note setback for tack shackle and cut the sail accordingly.

Luff Tape Size

6

Both units require #6 (

/32" or 5 mm) luff tape.

Luff Tape Length

Note feeder height and extend bottom of luff tape downward so it is
below feeder. This will prevent luff tape from catching in feeder as sail
is lowered.

Tack and Head Shackles

Make sure tack and head shackles fit
sail rings. Minimum inside dimensions
of standard head and tack shackles are:

Note: If a long link plate is used, add the following dimensions to feeder,
shackle and drum height (based on whether plate is used full-length or
shortened to one of five hole positions). Do not add to halyard swivel or

Preassembly Foil Length

Confirm foil length by laying foils alongside
stay with turnbuckle components.

Pull stay out so it is straight. Attach Harken
toggle to bottom of stay. Adjust turnbuckle
so that length of stay with Harken toggle
will fit boat. Ideally, turnbuckle will be
half to two-thirds open to allow for rig
adjustment.

Line up drum assembly so holes below
drum line up with holes in Harken toggle.
Make sure toggle is tensioned when
measuring.

Line up bottom foil so clamp screw holes
are lined up with third row of holes as
shown.

Note: Mark top foil so foil with trim cap will
ride 1/2" (12 mm) below terminal. If wire
fitting at top of stay is swage, foil must ride
just below shoulder of swage. Mark cut line
on foil. Wrap tape around foil as a guide
so cut is straight. Check length to see
if it matches results from chart on

Commissioning Halyard Wraps

Halyard Wrap

The most serious problem with furling systems occurs when the jib
halyard wraps around the headstay foil. Halyard wraps will keep you from
furling/unfurling and may cause serious damage to the unit and halyard.

WARNING! In severe cases, a halyard wrap can cause loss of
control of boat and/or headstay can break suddenly which can
cause an accident, damage to your vessel, personal injury, or
death. See www.harken.com for additional safety information.

To prevent wraps, the halyard must exert a slight pull to the rear. This
allows the foils to turn while halyard remains stationary.

Prevent Halyard Wraps

WARNING! Sail must be fitted to foil length before using to
prevent headstay loss which will cause an accident, damage
to your vessel, personal injury, or death. See www.harken.com
for additional safety information.

1. Halyard swivel should be within top 4" (100 mm) of foil unless a
halyard restrainer is used.

2. Halyard must pull slightly to rear (8–10°).

3. Halyard must be snug, but not too tight.
If halyard wraps, do not force unit to turn. Attempt to open sail by
carefully furling in and out a little at a time. If sail will unfurl, lower

8–10°

it by releasing jib halyard. Severe halyard wraps can only be cleared
by going aloft and freeing halyard.

If sail will not furl or unfurl, try to remove jib sheets and manually
wrap sail around headstay.

Testing at dock does not indicate halyard angle is correct. In wave
action, halyard may wrap if lead angle is not correct. The 8–10°
diverging angle shown at right is critical.

Pendants

If the your sail luff is not long enough to position the halyard swivel
properly, you must add a pendant. Pendants should be made of plastic­coated wire and be permanently attached so the sail height will be
correct. Adjustable length pendants are not acceptable as they
might not be adjusted correctly during a sail change.

Installing a Pendant

1. Raise sail, but do not attach tack shackle.

2. Position halyard swivel correctly near top of headstay.

3. Secure halyard.

4. Tie a piece of rope to sail tack.

5. Lead line through tack shackle on furling drum.

6. Tension sail.

7. Measure distance from tack shackle to sail tack and permanently
attach a pendant of this length to head of sail.

8. Repeat this procedure for every jib in your sail inventory.

22 Unit 1, 2 Cruising 08/23/10

Commissioning Halyard Restrainer

Halyard Restrainer

To prevent wraps, jib halyard must pull slightly to rear. On most boats,
halyard lead angle is acceptable if halyard swivel is raised to top of foil.

On some boats halyard sheaves are located too close to headstay and
a halyard restrainer must be used.

Halyard restrainers should be used only when required by masthead
geometry. Restrainers tend to limit sail luff length and may cause
problems if not installed properly.

If your boat needs a halyard restrainer, use Harken part 944.
Restrainer should be mounted as high as possible on face of mast.

Position restrainer so that foils will not hit it when under load.
The restrainer should deflect halyard as little as possible or you may

experience difficulty in tensioning sail luff, friction when furling, and
possible damage to foils. To decrease deflection angles, shorten sail luff.

Tip: Boats used in charter service should have a halyard restrainer,
regardless of masthead geometry.

Halyard Tension

The jib halyard should be firm, but not too tight.

Tip: The luff foil system supports sail along its length so halyard ten­sion is used only to shape sails, not to support them. Use enough
halyard tension to remove some wrinkles along luff of sail. Do not
tension halyard enough to cause vertical wrinkles in luff of sail.
Tension to adjust position of draft in sail to suit sailing conditions.
Halyard should be firm but not tight. If in doubt release halyard
tension. To protect sail, ease halyard when boat is not in use.

5/30/08 Unit 1, 2 Cruising 23

Operation Halyards/Headstay Tension

Spinnaker Halyards

Spinnaker halyards occasionally cause problems
with furling.

WARNING! In severe cases, spinnaker
halyards can jam furler causing loss of control
of boat which can cause an accident, damage
to your vessel, personal injury, or death. See
www.harken.com for additional safety
information.

On many boats it will not be possible to attach
spinnaker halyard to bow pulpit or it may be
"sucked" into jib when furling.

On some boats the spinnaker halyard lays across
headstay and will catch on halyard swivel, foils, or
jib halyard. To prevent problems it may be necessary
to install a masthead bail to move spinnaker halyard
block forward and to one side.

Boats with external halyards may find it necessary to
flip both ends of spinnaker halyard behind spreaders
to prevent fouling with furling system.

Headstay Tension

A furling system will work best if headstay is tight.
A loose headstay is difficult to rotate and can cause

unusual wear on foil joints.
To adjust headstay tension, remove sail and furling line

from unit and follow instructions on page 24.

Tip: Before adjusting headstay tension, slack
mainsheet and vang.

Backstay Adjusters

Backstay adjusters allow headstay tension to be varied to change sail shape to match
conditions. They permit a very tight headstay to be eased when boat is not in use.
For best performance, consider adding a backstay adjuster; either a block and tackle,
a mechanical adjuster like those offered by Harken, or a hydraulic adjuster.

Remember to keep headstay tight for best performance when furling or reefing.
If your boat is fitted with an adjuster be sure that it is tensioned before the halyard

is tensioned. If not, backstay adjuster may increase halyard tension and could
damage the sail or furling system.

Racing boats often slack the headstay completely when sailing downwind. Check
to be sure that foil does not jam against upper headstay terminal when backstay is
released. It may be necessary to shorten foil slightly to prevent this.

24 Unit 1, 2 Cruising 08/23/10

Operation Sail: Raise/Storm/Reef

Raise Sails

1) Shackle tack of sail to drum. Install shackle so screw pin head is on same
side as suncover.

2) Secure genoa sheets to clew of sail.

3) Attach genoa halyard to halyard swivel.

4) Pass luff tape through feeder into foil groove.

5) Attach head of sail or pendant at head of sail to halyard swivel.

6) Hoist sail.

Tip: New sails are often stiff and may hang up at feeder 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 multipurpose genoa for all their sailing, but it is not good seamanship to go offshore
without storm sails.

Heavy air working jibs and storm sails may 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 22.

Remember that heavy air working jibs and storm jibs may be reefed and furled like any other sail.

Furl and Reef

To furl or reef, ease the jib sheets and pull
furling line.

In very light air, it may be necessary to place
some tension on jib sheet to insure a tight furl.

In a 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 the Troubleshooting
Guide on page 28. Do not use a winch to force a system to turn.

You may use a winch to make furling easier, if you are certain that system is operating properly.

08/23/10 Unit 1, 2 Cruising 25

Operation Reef/Secure Sail

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 while entering or leaving harbors.

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.

You may also lock your system by aligning holes
in bottom of drum and basket and then using a
line to secure drum.

Be sure that mooring lines are not placed across
furling line where they may cause chafe.

Replace Line — Unit 1

Use HFG233 furling line or source a good quality line with good wear
characteristics. Use 9/32" (7 mm) line with break strength exceeding
2500 lbs (1130 kg). Smaller boats or smaller sails may allow
5/16" (8 mm) line.

Replace Line — Unit 2

Use HFG235 furling line or source a good quality line with good wear characteristics. Use 5/16" (8 mm) line with
break strength exceeding 3740 lbs (1700 kg). Smaller boats or smaller sails may allow 3/8" (8 mm) line.

Replace Line — Both

If a larger diameter line is desired, consult with a rigger about using tapered line with a high strength core and cover
removed in forward part of line.

Storage – Mast Down

In areas where it freezes, do not store system where water can accumulate in foils. When water freezes it will rupture
aluminum. Store foils under cover, with grooves facing down or on an angle so water will run out.

Storage/Transporting

Do not store or transport system with drum assembly extending beyond mast. Remove masthead clevis pin and shift
furler up so drum assembly can be strapped securely to mast. Some people remove drum assembly and halyard swivel
for storage and transport.

After Storage or Transport

After storing or transporting unit, clean thoroughly including ball bearings. See instructions above.

Remove Furler

Foils can lock against upper stay terminal when backstay is released. To prevent this loosen foil clamp screws and
lower foil before loosening backstay.
