Deck General · Shiphandling — Propeller Walk
A vessel with a single right-handed fixed propeller backing down (engine astern) will tend to walk her stern to:
- APort✓ Correct
- BStarboard
- CStraight back with no swing
- DEither side equally
Explanation
Transverse thrust (propeller walk) from a right-handed propeller going astern throws the stern to port (bow swings to starboard). Mariners use this predictable effect to twist or to bring the stern alongside a port-side berth.
