Given are the courses and speeds of 4 vessels. The navigator of which vessel would be required to know the actual time of meridian transit in order to take an accurate observation at LAN?

Correct Answer: Option B — C 166°T, Sp 24 knots

A vessel steaming rapidly along a meridian (e.g., course 166 degrees T at 24 knots) experiences a substantial change in latitude and longitude relative to the sun's sub-point, necessitating precise computation of local apparent noon to execute accurate meridian sights.
