Consult specifications for swivel and drum pin-to-pin lengths to determine luff length deductions. If using
optional hoistable halyard swivel, make sure to deduct for this.
Use a zippered luff sleeve or small snap straps so that the sail can be hoisted onto a permanent stay or
removed with the headstay left in place. Make sure the head and tack thimbles are secured to the sail to
handle furling loads.
Use tangs to provide a sail attachment to lower furler. A sailmaker eye may also be used.

Sailmaker Instructions
Attaching furling components to mast and boat
Attach the tang assembly to fork at top of drum using
¼" clevis pin. Attach drum assembly to boat’s chainplate using ¼" clevis pin.
As part of raising mast, attach upper halyard swivel to a tang on mast. Attach headstay wire with
hoistable swivel to upper swivel assembly. Attach fork fitting on lower end of wire to tack adapter
tang. Use “O” rings between tang and inside fork so clevis pin stays square to plate.
Furling Line Lead and Cleat
Feed line through one of openings in drum so it does not rub and through small hole in top of drum.
Tie a tight figure “8” knot in end of line and draw it tight onto drum.
Spin drum and wind up about 10' (3 m) of line. Furling line can be led down center on either side of boat.
Mount a 237 bullseye or 349, 29 mm Carbo block assembly placed so that furling line is perpendicular to
forestay. Lead line aft and mount a 238 cam cleat with fairlead. Tie a figure “8” knot in end of line. Charge
system by rotating furler spool to wrap line on drum. Tension line while charging. If you are using a sun-
cover note which side of sail is exposed.
Tip: Sun cover to starboard—turn clockwise to charge. Sun cover to port—turn counter-clockwise.
If you need to change direction sail furls, disconnect tack of sail. Pull line off spool and charge line in
other direction.
Raising Sail
Make sure that spool is charged with line as directed above. Attach tack of sail to adapter tang or
sailmaker eye. Attach head of sail to shackle on halyard swivel. Attach halyard to upper shackle. Hoist
sail and trial furling. Check furling line length. To change amount of line on drum, disconnect tack from
lower unit and rotate drum to add or remove line. Re-attach tack.
Check Halyard Angle
Make sure halyard has a slight pull to the rear. The lower pin in the upper swivel spins. If halyard is too
close to this pin, halyard can wrap causing sail to jam. There may be room to add a pendant between
head of sail and hoistable swivel to raise it. Alternatively it may be necessary to put a halyard restrainer
on the mast or lower halyard sheave. Use a modified 2129 eyestrap.
