■ Sail Type
The Harken furler will work with conventional sails or
sails with built in shaping devices such as Aeroluff
®
,
Pirini Luff or foam luff.
■ Luff Length
Note offsets above and below the sail.
A shorter luff may be required if a halyard restrainer is
necessary (page 30) or a toggle or link plates are used
(page 8) below the furler to raise the drum.
If the luff of the sail is not long enough to put the
halyard swivel near the top of the headstay foil,
make sure a pendant is added, see page 30.
■ Tack Setback
Note setback for the tack shackle and cut the sail
accordingly.
■ Luff Tape Size
Unit 2.5 requires number 6 (
6
/
32
" or 5 mm)
luff tape.
■ Luff Tape Length
Cut off the top of the luff tape so it is 18 to 24" (450 to
600 mm) below the head of the sail. This will allow the
head to lag behind the rest of the sail to help flatten
the sail. It will also help the head to roll more smoothly .
Note feeder height and extend the bottom of the luff tape
downwards so it is below the feeder. This will prevent
the luff tape from catching in the feeder as the sail is
lowered. *The 44

tomer's inventory.
