Step Ladder: If you are installing the system with
the mast up, use a step ladder that can be secured
to the boat near the mast.
You will need to work at a hand height of
about 7' (2.13 m) above the gooseneck.
Note: Track length is greater than luff length of sail.
The track must extend at least 8" above the point where the halyard is attached to
the Harken headboard. Allow for sail stretch.
Make sure the top of the track does not interfere with the halyard exiting from the
mast.
The set back for the halyard from the aft side of the mast is 3

Remember to leave

" (6 mm) beyond each end of the track for the end stops.
At the lower end, the track must extend as close to the gooseneck as possible
and ideally below the top of the boom.
Adjusting 1800 Track Length
The length of the track is matched to the mast by adjusting the number of 6'8 3 /

"
(2.05 m) track lengths and by cutting the top and bottom track pieces to length.
Consult chart below to determine how many total track pieces you will need.
Consult the charts below to determine whether you need to cut your top track to
length.
All mast lengths will require cutting the bottom track. A short bottom track allows
cars to be easily loaded. See page 10.
