- Q135 - Navigation Problems: Oceans
647. A vessel steams 1106 miles on course 249°T from LAT 13°30.0'N, LONG 144°30.3'E. What is the latitude and longitude of the point of arrival by Mercator sailing?
Mercator sailing yields an arrival position of LAT 0654.0′N, LONG 12708.0′E. Latitude change is calculated using dLat = D·cos C, and longitude change uses the meridional parts difference with dLo = DMP·tan C.
