Question 1871Navigation General

The correct answer is D) 000°. To determine the latitude of a vessel, you need to observe a celestial body (such as the sun, moon, or stars) on a bearing of 000° (true north). This is because the altitude of a celestial body observed on a north-south bearing is directly related to the latitude of the observer. By observing the altitude of the celestial body on a north-south bearing, you can use nautical tables and calculations to determine the latitude of your vessel. The other options are incorrect because observing a celestial body on bearings other than 000° would not provide the necessary information to determine the latitude. Option A (270°) is on an east-west bearing, option B (226°) is the course of the vessel, and option C (026°) is not a north-south bearing.
