Question 381 Rules of the Road

The correct answer is C) The vessel is not required to sound a fog signal. According to the Inland Navigation Rules, vessels less than 20 meters in length when at anchor in a special anchorage area approved by the Secretary are not required to sound a fog signal. The regulations do not mandate any specific fog signal for a 15-meter vessel anchored in a designated special anchorage area. Therefore, option C is the correct answer. The other options are incorrect because they describe fog signal requirements that do not apply to a vessel of this size anchored in a special anchorage area. Options A, B, and D would be correct for larger vessels or vessels not in a special anchorage area, but they do not accurately reflect the regulations for this specific scenario.
