On 25 December your 0330 ZT DR position is LAT 25°15.0'N, LONG 32°16.0'W. You are on course 145°T at a speed of 20 knots. What will be the zone time of sunrise at your vessel?

Correct Answer: Option D — 0647

Determine the LMT of sunrise for the given latitude using the Nautical Almanac. Convert to ZT by applying the longitude correction for the vessel's position. Account for the vessel's movement during the interval. The resulting zone time of sunrise is 0647.
