■ Conversion to Racing

For racing, lower the halyard swivel below the feeder
and remove the line guard assembly and drum from
the headstay. This allows use of both grooves for sail
changes and to tack genoas on the deck for maximum
luff length.

■ Lowering the Halyard Swivel

To lower the halyard swivel, remove the feeder and
lower swivel unit until it rests on the torque tube.
Replace the feeder. Use blue Loctite on the screw.

■ Drum Removal

1) Remove the sail and unwind the line from the
drum. The line can remain attached to the drum.
2) Use the 8 mm allen wrench provided to remove the
2 screws on the bottom of the guard assembly and
remove the two halves. Be careful screws are not
captive.
3) Use a 5 mm allen wrench to loosen the four
screws in the plastic drum and remove.

■ Halyard Swivel Removal

For serious racing you may want to remove the halyard
swivel.
Note: It is not possible to remove the halyard swivel
on a unit with Norseman/Sta-Lok or rod adapter stud
unless you disassemble the terminal stud. Make sure
you use a new Norseman/Sta-Lok wedge to reassemble
a Norseman/Sta-Lok fitting.
1) Remove the drum assembly.
2) Rig a secure, temporary headstay.
3) Loosen the backstay, mainsheet and vang so
that the headstay goes slack.
4) Remove the clevis pin holding the furling unit to
the chainplate.
5) Open the torque tube to release the upper locking
collar (see page 25 and 24). Thread the drum off
and slip the torque tube and halyard swivel off.
6) Slip the torque tube back on the foils and re-attach
the lower unit.
7) Re-attach the headstay to the boat.
