Question 4236 Deck General

The correct answer is D) Half ahead with hard over rudder, then full astern on inboard engine. This technique, known as a "Williamson Turn," is an effective way to turn a large twin-screw ship around in a tight space. By first going half ahead with hard over rudder, the ship will start to turn. Then, by going full astern on the inboard engine, the ship will pivot and complete the 180-degree turn quickly and efficiently, without excessive use of engine power. The other options are less effective. A) and B) would not generate enough turning force, while C) could cause the ship to lose control and potentially damage the engines.
