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—8" (203 mm) 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 3847, 3848—Bottom of track
will be approximately 3 /
8
" (10 mm) 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.

8
" (238 mm) piece
from finished end of one of the 6'9 1 /
