A navigator obtains a bearing on a single charted lighthouse at 0800 and plots the LOP. At 0830, a second bearing is taken on the same lighthouse. To plot a running fix, the navigator must advance the 0800 LOP. Along what track is the first LOP advanced?

Question

Accepted Answer

B. Along the vessel's DR track for the interval between the two observations — Bowditch Ch. 7 §702 specifies that the first LOP is advanced along the DR track to the time of the second observation. The DR track represents the vessel's estimated course and distance made good during the interval.

Answer

A. Along the bearing line of the second LOP

Answer

C. Along the reciprocal of the vessel's course

Answer

D. Along a line parallel to the second LOP
