On 25 April your 0930 zone time position is LAT 28°35'S, LONG 82°30'W. Your vessel is on course 300°T at a speed of 20.0 knots. Determine the zone time of LAN.

Question

On 25 April your 0930 zone time position is LAT 28&deg;35'S, LONG 82&deg;30'W. Your vessel is on course 300&deg;T at a speed of 20.0 knots. Determine the zone time of LAN.

Accepted Answer

Option A: 1131. Local Apparent Noon occurs when the Sun crosses the observer's meridian. Calculate the time difference between the DR longitude and the zone meridian. Adjusting for the vessel's speed and course toward the west, the time of LAN is determined to be 1131 based on the sun's transit.
