Question 533Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND Which statement is TRUE concerning a vessel of 150 meters in length, at anchor?
AI Explanation
The correct answer is A) She must show all-round white lights forward and aft.
This is correct because under both the International and Inland Navigation Rules, a vessel 150 meters or more in length when at anchor must display an all-round white light at the forward part of the vessel and a second all-round white light at the after part of the vessel. This requirement ensures the vessel's presence is clearly visible to other vessels in the area.
The other options are incorrect because B) showing a single all-round white light is not permitted for a vessel of this size, C) the display of working lights is mandatory, not optional, and D) none of the above statements are true for a 150-meter vessel at anchor.
