Rules of the Road · Responsibilities Between Vessels
Under Rule 18, a sailing vessel shall keep out of the way of which of the following vessels?
- AOnly power-driven vessels making way
- BPower-driven vessels, vessels engaged in fishing, and vessels not under command
- CVessels not under command and vessels restricted in their ability to maneuver✓ Correct
- DAll power-driven vessels and all vessels constrained by their draft
Explanation
Rule 18(b) requires a sailing vessel to keep out of the way of NUC and RAM vessels. Sailing vessels do NOT automatically give way to power-driven vessels in general — they have precedence over power-driven vessels. They also do not automatically give way to constrained-by-draft vessels; Rule 18(d) creates a more nuanced obligation. Fishing vessels also give way to NUC and RAM but not to sailing vessels.
