FOIL CUT LENGTH
Foil cut length is based on pin-to-pin length as measured from cen-
ter of upper pin (attaches the stay to the mast) to center of lower
pin (attaches the furling unit to the boat). Measurement includes the
masthead toggle.
To check foil length, lay foils alongside stay before
cutting top foil.
TOP FOIL CUT LENGTH
Instructions For Worksheet Below:
1 Fill in total pin-to-pin length.
2 Fill in A length.
3 Add A, B, E, F and subtract from total pin-to-pin length.
SUM = _________
4 Choose the number from foil multiplier below closest to,
but not greater than, sum from step 3. Fill in D length.
7 x 2133.6 = 14935.2
8 x 2133.6 = 17068.8
9 x 2133.6 = 19202.4
10 x 2133.6 = 21336.0
11 x 2133.6 = 23469.6
12 x 2133.6 = 25603.2

Preassembly Short Top Foil
If top foil is shorter than 93/4" (248 mm), use one of the following special techniques to ensure sufficient bearing
surface for the foil in the area of the halyard swivel.
31/2" (89 mm)
3" (76 mm)
21/2" (64 mm)
2" (51 mm)
11/2" (38 mm)
93/4" (248 mm) No special treatment required.
93/4" (248 mm)
95/8"–71/8" (244–181mm) Do not use plastic bushing
above top connector.
95/8"–71/8" (244–181 mm)
7"–51/2" (178–140 mm) Do not use plastic bushing
above top connector. Shorten top of connector and if
necessary shorten trim cap.
7"–51/2" (178–140 mm)
53/8"–4" (137–102 mm) Do not use plastic bushing
above top connector. Cut connector right at cross formed
by glue dispersion channels. Use single foil screw in top
foil only.
53/8"–4" (137–102 mm)
Under 11/2" (38 mm) Eliminate top foil and run foil
higher in drum assembly.

full length foil so two screws are used to assemble joint
instead of four. Do not use plastic bushings above top
connector.
*To allow for saw cut, position blade so upper half of
middle hole is preserved.

Deburr inside edge using a rat-tail file.
Cut foil to length using a hacksaw.
Tip: Mark top foil to distinguish from
cutoff piece.
Lay top foil alongside cutoff piece and
use a flat metal object (i.e. metal ruler)
to scribe top line of foil.

Lay top foil in line with others. Slide stay
into top foil and down the line of foils or
slide each foil up stay.
Cut out template at right. Line template up
with top of foil and scribed line. Tape in
place. Use a center-punch to mark holes.
Check center-punch marks to confirm
they are 3/8" (10mm) and 13/8" (35mm)
from top of foil.
Drill two 5/32" (4mm) holes for
trim cap.

Place halves of plastic bushings on stay so
hooked part of longer section faces out.
Tip: With foil screw holes up as shown
below, place longer half of isolator
with hook on upper half.
Install trim cap. Place each side over wire.
Push trim cap into foil to start then tap in
using hammer.

Slip 9.75" (248mm) connector on wire,
mating hook of plastic bushing with
connector.
Tip: In cooler weather, keep sealed
adhesive in pocket to keep warm. Use
instructions below to fill injector less
than half way; you will only use a small
amount of adhesive. Refill if needed
but do not keep open sealant for long
periods, use adhesive within 3 hours.
Use cap of adhesive to break seal. Remove
injector tip cap and plunger. Hold injector
at an angle with applicator tip facing down.
Squeeze adhesive into tube so the lower
half of the injector is full as shown. Keep
tip free of sealant to let air inside.

Start plunger into injector and immediately
hold upright so plunger is down and tip
applicator is up.
As sealant runs down towards the plunger
an air pocket will form near the tip. Push
plunger to evacuate the air. You are now
ready to begin injecting adhesive.
Hold plastic wedge in place with thumb
as you insert into foil. Line foil holes
with connector screw holes.
Put a drop of adhesive into screw holes.
