On 16 March your 0330 ZT DR position is LAT 22°36.0'S, LONG 76°16.0'E. You are on course 098°T at a speed of 16 knots. What will be the ZT of sunrise at your vessel?

Correct Answer: Option B — 0553

Determine the sunrise time for the vessel's latitude using the Nautical Almanac. Apply the longitude correction by converting the difference between the DR longitude and the standard meridian into time. Adjusting for the vessel's eastward movement toward the sunrise yields a zone time of 0553.
