waterline, or inclined slightly upward towards the bow.
IMPORTANT: it must not hang down. When you have
obtained this position, glue the bulb to the keel using
UHU acrylit or thick cyano. Allow the adhesive to cure,
then cut two 1.5 mm Ø retaining pins (part 51) from the
steel wire supplied, and pass them through the keel
bulb and the keel to retain it.
If you do not wish to use the keel bulb fairings, you
•
should finish the keel using the following procedure:
file the surface of the bulb as even, smooth and
symmetrical as possible, and fill any remaining holes
(e.g. using Order No. 924). Sand the filler back flush
when hard. NOTE: the smoother the surface of the
keel bulb, the lower the water resistance; careful work
pays dividends here.
Alternatively you can fit the keel bulb fairings (part 52).
•
In this case you must sand away the lead bulb until the
shells are a snug fit round it.
Screw the keel to the hull using a washer (part 43) and
•
the retaining nut (part 53); this holes the hull in a more
stable position in the boatstand for the following
stages.
The rubber gasket (part 54) is glued in the canopy
•
(part 55) using cyano. Don't cut the cord to final length
until you are just about to join the ends.
To complete the mast (part 56) you require the
•
aluminium mast sleeve (part 57) and the hardwood
dowel mast base (part 58). Sand the hardwood dowel
until it is an easy sliding fit inside the mast, then glue it
in the end of the carbon fibre tube. Sand the end flat,
and round off the end slightly. Cut the aluminium mast
sleeve to a length of 115 mm, and insert it in the mast
opening.
Slide the main boom bracket (part 59) and the mast
•
plate (part 60) down over the mast sleeve until they
rest on the deck. Check that everything is central, then
fix the mast plate to the deck using fillister-head screws
(part 33).
Assemble the main boom swivel bracket (part 61), the
•
washer (part 35) and the swivel axle (part 62), and
check that the axle rotates very freely; if not, sand it to
ease the fit.
Glue the main boom (part 64) in the main boom sleeve
•
(part 63). Screw the clamp nut (part 66) into the
depressor (part 65). TIP: the correct thread is on the
end with the notch. Push a large annular clamp (part
67) onto the main boom, fit one end of the depressor
into the annular clamp and secure it with a retaining
screw (part 68). Don't tighten the screw fully at this
stage; it must be possible to adjust the position of the
annular clamp on the boom.
Screw the main boom to the main boom swivel bracket
•
using two screws (part 68) and two retaining nuts (part
69).
Fit the jib hanger (part 70) on the mast and glue it in
•
place at a point about 95 mm from the top of the mast.
The masthead fitting (part 71) can now be glued to the
top of the mast. IMPORTANT: check that the
masthead fitting is exactly in line with the jib hanger.
Cut the backstay (part 72) from the white polyester cord supplied. Cut a piece from the large loop of one
•
wire hook (part 73), as shown in the drawing, and apply a drop of cyano to the point where the two loops
