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 37) 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
headstay foil, a pendant must be added. See page 36.
Tack Setback
Find setback "C" for tack shackle in chart below and modify sail
accordingly. Setback is measured to luff tape of sail.
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 to 24" (450 to 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:
