Two power-driven vessels are in a crossing situation so as to involve risk of collision. Under Rule 15, which vessel is the give-way vessel?
- AThe vessel that is making the greater speed
- BThe vessel that is smaller in length
- CThe vessel which has the other on her starboard side✓ Correct
- DThe vessel which has the other on her port side
Explanation
Rule 15 requires the vessel that has the other on her starboard side to keep out of the way. Memory aid: the give-way vessel sees a red (port) light on the crossing vessel — a reminder to stop. Speed and size are irrelevant to this determination.
