You may BEST turn a twin-screw vessel about, to the right, in a narrow channel by using _______________.
AI Explanation
The correct answer is C) port engine ahead and the starboard engine astern.
This is the correct answer because in a narrow channel, using differential thrust between the port and starboard engines is the most effective way to turn a twin-screw vessel to the right. By putting the port engine ahead and the starboard engine astern, you create a turning moment that will cause the vessel to pivot about its midpoint and turn to the right.
The other options are less effective or incorrect in this situation. Using both engines ahead with helm (A) would provide less turning force. Using only one engine (B) would result in a very wide turning radius. And using both engines astern with helm (D) would cause the vessel to back down rather than turn.
