Question 624 Rules of the Road

The correct answer is A) The vessel may be using nets, lines, or trawls. This is correct because the term "vessel engaged in fishing" refers to a vessel that is actively using fishing gear such as nets, lines, or trawls to catch fish, regardless of whether it is moving or stationary. This is defined in both the International and Inland Navigation Rules. The other options are incorrect because B) a vessel engaged in fishing does not necessarily sound the same fog signal as a vessel underway, making no way, C) a vessel engaged in fishing may be trolling (towing fishing lines) in addition to using other gear, and D) a vessel engaged in fishing does not necessarily show 2 lights in a vertical line, white over red.
