Question

At 1800 zone time, on 7 December, your DR position is LAT 22&deg;48'S, LONG 91&deg;26'W. You are steering 320&deg;T at a speed of 14.0 knots. What is the zone time of sunset?

Accepted Answer

Option C: 1842. Calculate the time of sunset for the DR position using the Nautical Almanac sunset tables. Adjust for the vessel's change in longitude and latitude during the interval between the DR time and the estimated sunset. The resulting zone time for sunset is 1842, following standard celestial navigation interpolation methods.
