ried up inside of a foil.
Too many strung on wire.
Dirt or burrs in foil or on connector.
Swage stud is bent
Connectors too tight on wire.
Dirt or burrs in foil or on connector
Stay is too short.
Probable Cause
Check for missing connector inside of foil extrusions. If connector is
not inside extrusion call Harken for a special split top connector.
Leave extra connector loose inside last 7' (2.13 m) foil.
Clean connector and foil. Deburr as needed.
Return stay to distributor. Do not attempt to straighten swage.
Tape connectors again leaving 1" (25 mm) between connectors.
Clean connector and foil. Deburr as needed.
Add a toggle to the headstay to increase length. Do not sail with

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.
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.
Ease jib halyard.

Secure spare halyards away from the furling headstay, possibly by flipping halyards behind
spreaders
Flush bearings with freshwater and lubricate with dry spray lubricant such as McLube
Overrides are best prevented by using a #019 Little Hexaratchet block as the last furling line
lead to maintain proper drag on line while unfurling.
Make sure knot is pushed up inside drum.
Consult professional rigger.
Luff completely before furling or reefing.
Free jib sheets.
Reinstall foil in torque tube and tighten clamp.
Replace three screws holding torque tube to drum.
Remove sheets. Rotate stay wrapping as much furling line on the drum as possible.
Tighten line guard screws securely.
Rerun line.
Remount swivel corretly.

Free furling line.
Remove sheets. Rotate stay, wrapping as much furling line on drum as possible.
Adjust amount of line on drum or change position of forward block to allow line to roll evenly
on drum.
Move halyards away from furling headsail as above.
Tighten headstay and/or backstay to eliminate sag in headstay.
Maintain drag on sheets while furling.
Secure furling line.
Check luff tape for fraying.
Check luff tape size.
Flake sail more loosely on deck.
Clean groove.
Luff of sail is too long and must be recut.
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.
Angle between headstay and halyard is too shallow and must be optimized per the installation
instructions.
Foil is too short or low and must be lengthened or raised.
Remove sheets. Pull line to remove all furling line from drum. Turn stay to rewind line on
drum in opposite direction. Line guard and cowling alignment may need to be adjusted.
