In the described scenario, which vessel is permitted to take action to avoid collision if the other vessel is not acting?

• A. Give-way vessel
• B. Both
• C. Stand-on vessel
• D. Neither

Answer: (C)

The key idea is how COLREGS handle risk of collision when one vessel isn’t taking action. The stand-on vessel normally keeps its course and speed, but if it becomes clear that the give-way vessel is not taking appropriate action to avoid a collision, the stand-on vessel is permitted and expected to maneuver to avoid danger. This rule ensures safety by allowing the vessel that would otherwise be compelled to maintain its track to take evasive action when the other vessel fails to act. The maneuver can be to alter course, slow down, or otherwise adjust movement early and with due care to prevent a collision. In this scenario, that authorization and obligation falls on the stand-on vessel.
