In a head-on meeting between two power-driven vessels, what maneuver should each vessel perform to reduce risk of collision?

• A. Stop and drift
• B. Alter course to port
• C. Alter course to starboard
• D. Maintain original course

Answer: (C)

In a head-on meeting between power-driven vessels, the standard action is for each vessel to alter course to starboard (to the right) so that they pass on the other vessel’s port side. This creates a predictable, symmetrical change that avoids crossing paths and reduces collision risk. Stopping and drifting offers neither a predictable path nor adequate control, maintaining the current risk. Maintaining course keeps both vessels on a collision course. Altering to port would not align with the agreed passing side in a head-on situation, which is why turning to starboard is the correct maneuver.
