Question 661 Rules of the Road

The correct answer is C) A vessel mineclearing. Under the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a "vessel restricted in her ability to maneuver" is defined as a vessel engaged in an operation such as mineclearing. This type of vessel has limited ability to deviate from its course or stop quickly, making it a "restricted vessel" under the rules. The other options are incorrect because a vessel engaged in fishing (A) is not considered restricted, a vessel not under command (B) is a separate category, and a vessel at anchor (D) is also not restricted in its ability to maneuver.
