You are keeping ZD +4 on your vessel. On 21 June at 0906 DST, your position is LAT 30°48.0'N, LONG 71°00.0'W. You are on a course of 167°T at 15.2 knots. At what time will local apparent noon (LAN) occur ZT at your vessel? You are keeping DST.

Correct Answer: Option C — 1245

Convert the DR position to the zone meridian (75°W). Since the vessel is in Daylight Saving Time (ZD +4), adjust the zone time accordingly. Apply the Equation of Time for 21 June. The vessel's movement away from the meridian results in a calculated LAN of 1245 ZT.
