You are on a single-screw vessel with a right-handed propeller. The vessel is going full speed astern with full right rudder. The bow will swing __________.

Correct Answer: Option B — probably to port

Transverse thrust from a right-handed propeller creates a strong lateral force to port when backing. While right rudder normally steers the stern to starboard, the overwhelming transverse force at full astern typically causes the vessel to back to port, making this the most probable outcome in practice.
