Appendix
Dimensions/Sailmakers's Instructions
Luff Length
Note offsets above and below sail.
A shorter luff may be required if a halyard restrainer is used or
an additional toggle assembly is used to raise unit.
If luff of sail is not long enough to put halyard swivel near top
of headstay foil, a pendant must be added. See page 25.
Tack Setback
Note setback for tack shackle and cut sail accordingly.
Luff Tape Size
Unit 5H requires #6 (
6
/
32
" or 5 mm) luff tape.
Luff Tape Length
Cut off top of luff tape so it is 24 to 36" (600 to 1000 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 Lashing
Choose high strength low stretch line to lash head and tack to
fittings. Use specialty knots such as a triple fisherman's knot. See
knot tying resources at www.harken.com/knots.
Sun Cover
Sun covers may be installed on either side of sail. Be sure to match
other sails in the customer's inventory.
