Multiple Choice

After calculating CPA and TCPA for a potential collision, which regulatory framework guides the required maneuver decisions?

After you’ve computed CPA and TCPA, the action you must take to avoid a collision is governed by COLREGs. These rules specify which vessel must maneuver and how to maneuver in different scenarios, so they translate a numerical risk assessment into an actual, compliant maneuver. COLREGs designate the give-way and stand-on responsibilities. The give-way vessel must take early and substantial action to avoid a collision, which can mean altering course and/or reducing speed. The stand-on vessel should maintain its course and speed, but be prepared to take action if the risk of collision increases. In practice, this means applying the rules for specific situations: in crossing paths, the vessel with the other on its starboard side is the give-way; in head-on situations, both vessels typically alter course to starboard; and in overtaking, the overtaking vessel must pass clear. These prescribed actions are what ensure a predictable and safe resolution to potential collisions. The other options aren’t the governing framework for deciding maneuver actions in this context. The International Weather Code isn’t about navigation rules, Inland Waterway Rules apply to inland waters rather than open seas, and Ship’s Internal Procedures are company-level guidelines, not the global regulatory framework for collision avoidance.
