Sail Modifications (See page 12)
1. Mainsail headboard
A. Drill new halyard location
B. Drill attachment to accept clevis pin for 3811/3827 headboard car coupler.
2. Batten receptacle on sail to accept 10 mm threaded stud.
Note: Harken does not supply receptacle.
3. Becket spacer on sail for 1777, 3812, 3828, or 3831 intermediate cars.
Determine Track Length
Measure track length from point 1 to point 2. See diagram at left. Use this
measurement in two charts to follow.
1. Upper end: 203 mm (8") above black band. Track is longer than sail luff
length to allow for stretch as sail ages. Track
must not
block halyard exit.
2. Lower end: Bottom of track will be approximately 10 mm (3/8") above
gooseneck fitting. When installed 3824, 3825, 3826 endstop kit track
should be as low as possible yet you should still be able to install long
headboard cars. Test measurement by using long headboard car. See
photo at right.
3808, 3809, 3810 Endstop kit: Cut a 203 mm (8") piece from finished end of one of the
2.05 m (6'8 7/8") 3807 tracks. You will remove this track when loading cars so it can be
lower on mast. See page 7, step 11. Drill lower hole for stop. See page 5, step 3.
