A furler that binds is usually a halyard wrap, a seized swivel, or a worn bearing — and the fix gets cheaper if you catch it before the foil bends.
What to Check
1
Halyard wrap
If the halyard wraps around the foil at the masthead, the furler locks up. Common after a halyard-tension change. Look up.
2
Bottom drum bearing
Salt + sun + neglect kills lower bearings. Spin the empty drum by hand — should turn freely.
3
Top swivel
Top swivels seize from corrosion. The sail will twist at the head — go up the rig and inspect.
4
Sun-rotted UV cover
If the sail's leech UV strip is shredding, the sail itself may be wedging in the furler.
