UK Furling Considerations

Preventing Halyard Wrap If you have a roller furling system, it is important to keep the halyard swivel high enough to prevent the halyard from wrapping around the headstay. The diagram at right shows a properly selected luff length. The halyard swivel is close to the top of the mast, and there is a slight difference in angle between the headstay and the halyard.
This diagram shows a luff length that is a little too short. This could allow the halyard to wrap around the headstay. as the sail furls or unfurls. PC sails are available in luff length increments of 6", so it is unlikely that this situation will develop if measurement procedures are followed carefully.
If the luff of your PC sail is causing halyard wrap, you will need to install a short head or tack pennant. A pennant is a short piece of wire or rope that effectively lengthens the luff, preventing halyard wrap You can also prevent halyard wrap by installing a halyard retaining bail. The Profurl systems use wrap stoppers to prevent halyard wrap. Consult your furling system owners manual for more details.

Ultra Violet Protection:
If you have a roller furling system, chances are that you will be storing you PC headsail on the furler for periods of time. For this reason, the area of your PC RF Genoa that will be exposed when stored is protected by an extra layer of fabric called a sunshield.

The sunshield of your PC RF Genoa is on the starboard side of the sail. For the sunshield to protect the sail, the drum of your roller furler must rotate counter clockwise when you pull on the furling line.

If your system presently rotates clockwise when you pull on the furling line, you will need to wrap the line in the opposite direction. To do this first remove your present sail from the system. When the sail is off and detached, pull the furling line until it is entirely off the drum, and wind it back on in the opposite direction, turning the system by hand in a clockwise direction.

Should this result in an unfair lead to your first furling line lead block, consult your furler manual for directions on how to re-position the fairlead arm and or drum basket to achieve a fair lead.
