Deck General · Mooring — Self-Tensioning Winches
A hazard of leaving mooring winches in automatic self-tension mode alongside is that:
- AThe lines never move
- BThe winch may render and heave repeatedly, surging the vessel and overloading other lines unevenly✓ Correct
- CThe winch uses no power
- DIt tightens all lines equally and safely
Explanation
In auto-tension, a winch pays out and heaves to hold set tension; this can cause the vessel to walk along the berth and shift load onto adjacent lines, risking parting. Many operators secure winches on the brake (not auto-tension) once moored.
