Question 941 Rules of the Road

The correct answer is C) The vessel shall ring a bell for 5 seconds every minute. This is correct because under both the International and Inland Navigation Rules, a sailing vessel 25 meters or more in length, when at anchor in a "special anchorage area" approved by the Secretary, is required to sound a bell for 5 seconds every minute to indicate its presence during periods of restricted visibility. The other options are incorrect because A) and D) specify the use of a whistle, which is not the correct sound signal for an anchored sailing vessel in a special anchorage area. Option B) is incorrect because the vessel is required to sound a fog signal when anchored in these conditions.
