On 19 July your 1500 ZT DR position is LAT 28°25.0'N, LONG 120°28.0'W. You are on course 233°T at a speed of 10 knots. What will be the zone time of sunset at your vessel?

Correct Answer: Option C — 1901

Utilize the Nautical Almanac's 'Sun' tables for sunset. Apply the corrections for latitude and longitude difference from the standard meridian. Interpolating for the vessel's latitude of 28°25.0'N and the date of 19 July yields a local apparent sunset time of 1901, adjusted for the specific zone time.
