On 17 November your 1530 ZT DR position is LAT 27°13.0'S, LONG 153°21.0'W. You are on course 261°T at a speed of 14 knots. What will be the ZT of sunset at your vessel?

Correct Answer: Option A — 1845

Calculate the sunset time using the Nautical Almanac for the given date and latitude. Adjust the tabular time for the vessel's longitude and the change in position due to the vessel's movement during the interval. Interpolation between latitude entries ensures precision, resulting in a local zone time of 1845.
