For installation to a new vessel, the positioning of the gooseneck will be deter-
mined as per the information on page 6. It is wise to measure “P” from the top of “P”
to the bottom of “P”. This will confirm the gooseneck position as per Diagram 1.
In all instances it would be preferable to check with the owner, for the preferred
position, because of the greater depth of the boom.
INSTALLATION INSTRUCTIONS – fitting the sail track, track slugs
1. After confirming the gooseneck position make a reference mark for the position
datum which is the center of the drive shaft.
Note : The datum position is the reference for all measurements.
2. See Diagram 1, mark a position above datum where the base extrusion will finish.
Refer to Diagram 3a and mark the location of the top of the base extrusion. The top
piece of base extrusion is to be the “cut length” so the base assembly spans the
distance between the top and bottom reference marks. There must be .020 gap
(thickness of two business cards) between each length of base extrusion.
3.
Luff track and track base must be installed before any other fittings are
attached to the aft face of the mast.
4.
Insert 18 or more mounting slugs into the mast luff slot, raise to a convenient
waist level and place a piece of masking tape across slot to hold up the slugs.
5.
Hold the cut length of base extrusion, that has the fairing block attached, against
the back of the mast and thread a ¼-20 flat head machine screw (FHMS) through
the base and into the slug.
6.
While pushing the track base upward as you work, engage a slug for each hole in
the base.
7.
When the first set of slugs are installed, send the first base section to the person at
the masthead for tightening in place while the second track base is being prepared
below. Position this first “cut length” section of base extrusion at the reference mark
based on diagram 3a for the location in relation to the main halyard sheave.
8.
Alternately, if you are working alone, once you have raised this first section to the
top of the mast and fixed it in place, you can install successive sections pushing
them up the mast as you progress. The base weighs .49 lbs./ft., or 25 lbs./50 ft.
9.
Introduce more slugs into the mast luff slot as needed. Progressively add track
base sections and tighten the screws. Ensure that there is a .020 gap (thickness of
two business cards) between all of these sections and make sure each joint is well
aligned. The bottom of the last base extrusion has holes drilled and tapped for
securing the flex feeder piece.
