Question 1008 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), a vessel restricted in her ability to maneuver must sound the same fog signal, which is a prolonged blast, regardless of whether the vessel is underway or at anchor. This distinguishes her from other vessels, such as those constrained by their draft (A), sailing vessels (C), or vessels not under command (D), which have different fog signal requirements. The other options are incorrect because they do not have the same fog signal requirements as a vessel restricted in her ability to maneuver.
