Furling Attachment to Boat
Check mast fitting to make sure there is a tang to fit the clevis pin and jaw width of the upper halyard swivel.
Check the chainplate to make sure the drum assembly will fit.
Rigging work
Make sure you have a stay made up with the correct hardware and with swivel correctly captured on stay.
Consult Sailmaker to make sure sail is compatible with hardware. See below.
• Have fairleads or block and cleat to secure line.
• Purchase furling line per specifications above.
• Check halyard clearance of upper swivel.

Headstay Wire
Consult the pin-to pin-lengths for the upper swivel, adapter tang and the drum assembly. Make up wire
so that it has an ¼" eye to mate with the upper swivel assembly. The lower end requires a fork to mate
with the HCP649 Tack Adapter Tang. A sailmaker eye may be used as an alternative. The eye consists
of a swage marine eye with a hole designed for lashing or shackling the tack to the terminal. Sailmaker
eyes are available from rigging supply companies.

Adapter Tang Assembly
The hoistable ball bearing swivel is installed on headstay so you can raise or lower sail without removing
headstay. The hoistable swivel is independent of the headstay, allowing you to tension the luff separately from
the mast rake. The adapter tang assembly provides a “Y” attachment to connect both stay and sail tack to the
lower unit.
How It Works
Important! Make sure to have the hoistable halyard swivel installed on the wire before ends are
swaged in place. Make sure the top side of the halyard swivel with circlip ring facing is towards the
top as shown.
