Deck General USCG Question #4143 (Set 132)

You are stopped with no way upon your vessel at the pilot station. Your vessel is a large twin-screw ship. You must come around 180° to board your Pilot. How should you use the engines and rudder to turn the ship fastest in the least amount of space?

Official USCG Answer & Rule Citation

Correct Answer: Option C — Half ahead with hard over rudder, then full astern on inboard engine

Starting with half ahead and a hard-over rudder utilizes hydrodynamic lift to build initial turning momentum. Reversing the inboard engine creates a powerful turning couple pivoting the vessel around its center in minimal sea room, adhering to standard twin-screw maneuvering principles for zero-speed conditions.
