Question 33 AB01 - Able Seafarer

The Correct Answer is C 1. **Why Option C ("Maintain course and speed") is correct:** The vessel displaying a high-intensity all-round flashing red light is identified as a Law Enforcement Vessel (LEO) engaged in law enforcement activity, as defined by both International (COLREGs Rule 1) and Inland Rules (372.01). Inland Rule 34(b) (or the corresponding local rule referenced in COLREGs) states that when a vessel is directed to maintain course and speed by a law enforcement vessel using this signal, the directed vessel (you) must comply. If you were involved in a crossing situation where you are the stand-on vessel (which would typically be the case if the LEO is directing you), you must maintain course and speed unless the immediate danger of collision makes it unavoidable to act otherwise (Rule 17). In the context of this specific signaling requirement, the law enforcement vessel is essentially directing your action as the stand-on vessel in that interaction. 2. **Why the other options are incorrect:** * **A) Remain clear of the vessel:** While generally good practice, this is the responsibility of the LEO vessel if they are maneuvering, or the responsibility of the give-way vessel if a Rule 15 crossing situation exists. If the LEO is directing you to maintain course and speed via the flashing red light, "Remain clear" is too general and contradicts the specific legal directive given by the signal. * **B) Alter course to starboard:** Altering course to starboard (a typical action for a give-way vessel) is incorrect because the Law Enforcement Signal (flashing red light) overrides the standard crossing rules to the extent that you are being directed to maintain your current path. Altering course without explicit direction or extreme necessity would violate the LEO's directive. * **D) Reduce Speed:** Reducing speed is an action typically taken by the give-way vessel to allow the other vessel to pass. Similar to altering course, this violates the specific directive implicit in the LEO signal, which mandates that the directed vessel **maintain course and speed** to facilitate the LEO's operation or investigation.
