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— 305 mm (12") 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, using 3875—Bottom
of track will be approximately 13 mm (
1
/
2
")
above gooseneck fitting. When installed,
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 above.

piece from finished end of one of the 2.08 m
