On 26 September your 0830 zone time DR position is LAT 26°04.0'N, LONG 129°16.0'W. Your vessel is on course 119°T at a speed of 20.0 knots. What is the zone time of local apparent noon (LAN)?

Correct Answer: Option A — 1124

Local Apparent Noon occurs when the Sun crosses the observer's meridian. Calculate the longitude in time (129°16'W = 8h 37m 04s). Adjust the 1200 LAN by the difference between the DR longitude and the zone meridian (135°W). Applying the vessel's movement toward the Sun yields 1124 zone time.
