Question 280 Rules of the Road

The correct answer is B) a vessel restricted in her ability to maneuver. According to the International Regulations for Preventing Collisions at Sea (COLREGS), Rule 18, a vessel fishing must keep out of the way of a vessel that is restricted in her ability to maneuver. This is because vessels restricted in their ability to maneuver, such as those engaged in dredging or underwater operations, have a limited capacity to take evasive action, and therefore have the right-of-way. The other answer choices are incorrect because a vessel under sail (A) and a vessel engaged in pilotage duty (C) do not have the same priority as a vessel restricted in her ability to maneuver. A vessel towing another vessel (D) is also not the correct answer, as the towing vessel would be considered restricted in her ability to maneuver.
