Harken 7410.11 MKIV Jib Reefing & Furling - Manual (Page 6)

6 MKIV Underdeck Unit 0
Preassembly Dimensions/Sailmaker's Instructions
Luff Length
Note offsets above and below sail.
A shorter luff may be required if a halyard restrainer is necessary
(page 30).
If luff of sail is not long enough to put halyard swivel near top of
headstay foil, a pendant must be added. See page 29.
Tack Setback
Note setback for tack shackle and cut the sail accordingly.
Luff Tape Size
All units require #6 ( 6 /
32
" or 5 mm) luff tape.
Luff Tape Length
Cut off top of luff tape so it is 18–24" (450–600 mm) below head
of sail. This allows head to lag behind rest of sail to help flatten
sail. It will also help head to roll more smoothly.
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. The minimum inside dimensions
of standard head and tack shackles are:
