Your 0000 zone time position on 13 June is LAT 24°35'N, LONG 142°26'E. Your vessel is on course 245°T, speed is 13.5 knots. What is the zone time of sunrise?

Correct Answer: Option B — 0445

Determine the sunrise time for the vessel's latitude using the Nautical Almanac. Account for the vessel's movement along its course and speed to update the longitude for the time of sunrise. Applying these corrections to the tabulated data yields the accurate zone time of 0445 for the vessel.
