On 10 July your 0930 zone time DR position is LAT 26°31.0'S, LONG 4°41.0'E. Your vessel is on course 308°T at a speed of 22.0 knots. What is the zone time of local apparent noon (LAN)?

Correct Answer: Option A — 1149

The DR position is at 4°41.0'E, which is 18.9 minutes of time west of the 0° zone meridian. Accounting for the vessel's speed of 22 knots on course 308°T, the vessel moves toward the meridian, resulting in a LAN time of 1149. This follows standard celestial navigation time-keeping procedures.
