Solution
Sail will not furl or
is difficult to furl.
Jib halyard is wrapping around headstay because angle
between mast and and halyard is too shallow.
See installation instructions regarding optimal halyard angle. It may be necessary to
mount a halyard restrainer on the front of your mast to hold the halyard to the rear.
Jib halyard is wrapping around the headstay because
the halyard swivel is too low.
See installation instructions regarding optimal halyard swivel height. A wire pendant may
be needed at the head of the sail to raise the halyard swivel to the proper height.
Jib halyard is too tight.
Ease jib halyard.
Foils too high, binding on swage eye.
Open turnbuckle or shorten foils.
Spare halyard is wrapping in sail as it furls.
Secure spare halyards away from the furling headstay, possibly by flipping halyards behind
spreaders
Salt or dirt in bearings.
Flush bearings with freshwater and lubricate with dry spray lubricant such as McLube
®
.
Furling line tangled in drum.
Overrides are best prevented by using a #7402 as the last furling line lead to maintain proper
drag on line while unfurling.
Stop knot catching.
Make sure “hog ring” used instead of knot.
Bent or “banana” swage stud.
Consult professional rigger.
Sail full of wind.
Luff completely before furling or reefing.
Jib sheets are not free.
Free jib sheets.
Foil out of torque tube.
Secure with foil key.
No wraps of furling line on drum.
Remove sheets. Rotate stay wrapping as much furling line on the drum as possible.
Lineguard assembly has slipped down.
Tighten line guard screws securely.
Line through #019 backwards.
Rerun line.
Halyard swivel installed upside down.
Remount swivel corretly.
Sail will not unfurl

completely.
Insufficient furling line on drum.
Remove sheets. Rotate stay, wrapping as much furling line on drum as possible.
Too much line on drum.
Adjust amount of line on drum or change position of forward block to allow line to roll evenly
on drum.
Spare halyard catching in sail as it furls.
Move halyards away from furling headsail as above.
Headstay rotates in
jerks or elliptically.
Insufficient tension on headstay.
Tighten headstay and/or backstay to eliminate sag in headstay.
Sail does not stay
furled.
Sail not furled tightly on stay.
Maintain drag on sheets while furling.
Furling line not secure.
Secure furling line.
Sail will not go up.

Clean groove.
Sail will not raise
completely or luff
will not tension.
Halyard swivel is hitting end stop.
Luff of sail is too long and must be recut.
Angle between halyard and mast is too sharp and
halyard is pulling too much to the rear.
Halyard must be routed from a point higher on the mast. This may require that any
halyard turning blocks aloft be replaced or the sail shortened.
Sail will not
come down.
Halyard is wrapping on headstay.
Angle between headstay and halyard is too shallow and must be optimized per the
installation instructions.
Halyard swivel off foil.
Foil is too short or low and must be lengthened or raised.
Ultravoilet cover rolls
up inside of sail.
Furling line is wrapped on drum in wrong direction.

Foil will not slip past threaded stud.
Dirt or burrs in foil or on connector.
Clean connector and foil. Deburr as needed.
Swage stud is bent
Return stay to distributor.
Do not attempt to straighten swage.
Connectors too tight on wire.
Tape connectors again leaving 1" (25 mm) between connectors.
Connector will not fit into foil extrusions.
Dirt or burrs in foil or on connector
Clean connector and foil. Deburr as needed.
Stay is too short.
Stay shortened too much when cut to install connectors
Add a toggle to the headstay to increase length.
