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:

Suncovers may be installed on either side of sail. Be

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
