On 16 January your 0930 ZT DR position is LAT 26°07.0'S, LONG 51°43.0'E. Your vessel is on course 238°T at a speed of 17.0 knots. What is the ZT of local apparent noon (LAN)?

Correct Answer: Option A — 1145

Local apparent noon occurs when the Sun's upper limb transits the observer's meridian. Using Bowditch methods, apply the equation of time and longitude correction to the DR position, factoring vessel motion from the initial ZT to determine the exact zone time of LAN.
