6.5 Troubleshooting

Problem

Probable cause

Action

6.5.1

”The sail will not unfurl or will only 

partly unfurl.”

• The jib halyard is wrapped around the 

luff extrusion.

• Ease the halyard slightly and try to 

reverse the system.

• Another halyard is wrapped around the 

luff extrusion.

• Furl the system. Free the halyard.

• The furling line is not free to run or has 

become tangled.

• Slacken or free the furling line. 

• The forestay is too slack. 

• Tension the forestay, first of all by 

tensioning the backstay and/or the cap 

shrouds. If this doesn’t help, decrease 

the length of the Furlex-system.

• Dirt and salt in the bearings.

• 

Rinse the bearings with fresh water and 

lubricate with Furlex grease.

• Too much strain on the halyard.

• Ease the halyard off.

6.5.2

”The sail will not furl, is hard to furl 

or can only be partly furled”

• The jib halyard is wrapped around the  

luff extrusion. 

• Ease the halyard slightly and try to 

reverse the system.

• Another halyard is wrapped around the 

luff extrusion.

• Unfurl the system. Free the halyard. 

• There is no line left on the drum.

• Unfurl the sail. Take it down and wind 

more line on the drum. Alternatively, 

loosen the sheet, gather the sail around 

the system and wind more line onto the 

drum.

• The forestay is too slack.

• Increase forestay tension.

• Excessive wind pressure on the sail.

• Let the leeward sheet off more.

• Windward sheet is not released.

• 

Release the sheet.

• The sheet has become tangled.

• Sort out the sheet.

• The free turn is not functioning.

• 

Rinse the bearings with fresh water and 

lubricate with Furlex grease. 

• Large turning angles in the furling line 

route which increase friction.

• 

Reroute the furling line, avoiding large 

turning angles.

• Dirt and salt in the bearings. 

• 

Rinse the bearings with fresh water and 

lubricate with Furlex grease.

• The furling line has become tangled on 

the drum.

• Unfurl the sail and take it down. 

Rewind the furling line. Unfurl the sail 

with slight drag on the furling line in 

the future and avoid having too much 

line on the drum.

• The line guide fitting chafes against the 

drum.

• Loosen the fastening screw below the  

drum and adjust the fitting.

• The halyard swivel is upside down.

• Fit the halyard swivel correctly.

• Too much strain on the halyard.

• Ease the halyard off a little.

6.5.3

”The system ‘wobbles’ when furling 

and unfurling”

• The forestay is too loose.

• Tension the backstay and/or the cap 

shrouds. This will tension the forestay.

6.5.4

”The sail unfurls after reefing or 

furling”

• The sail is not furled tightly enough.

• Furl with some drag on the line.

• The furling line is not belayed.

• Furl and belay the furling line.

6.5.5

”The sail is hard to hoist”

• The luff tape is too thick.

• 

Return the sail to the sailmaker and 

refer to the sailmaker information in 

this manual.

• The sail is caught on something or is 

not sufficiently loose on the foredeck.

• Arrange the sail better on the foredeck. 

• Fault in halyard routing.

• Check the sheaves, winch etc.

• Dirt and salt in the luff groove.

• Clean the luff groove.
