Question 947 Rules of the Road

The correct answer is B) A vessel restricted in her ability to maneuver at anchor. According to the International and Inland Navigation Rules, a vessel engaged in fishing underway is required to sound the same fog signal as a vessel restricted in her ability to maneuver at anchor. This is specified in Rule 35(d) of both the International and Inland Navigation Rules. The other options are incorrect because they do not match the fog signal requirements for a vessel engaged in fishing underway. A vessel being towed, a sailing vessel at anchor, and a power-driven vessel stopped and making no way through the water have different fog signal requirements.
