On 10 November your 1630 zone time DR position is LAT 25°10.0'N, LONG 71°12.0'W. You are on course 335°T at a speed of 24 knots. What will be the zone time of sunset at your vessel?

Correct Answer: Option D — 1700

Estimate the DR position at the approximate time of sunset. Extract the tabular sunset time from the Nautical Almanac for the given latitude and date. Apply the longitude correction to convert the tabular time to the vessel's zone time, resulting in 1700.
