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

Calculate the DR position at the estimated time of sunrise using the vessel's speed and course. Apply the Nautical Almanac sunrise tables for the latitude, interpolating for the date and longitude correction. The resulting zone time accounts for the vessel's movement toward the sunrise meridian, yielding 0445.
