Question 1400Navigation General

The correct answer is D) The course and speed made good should be determined and used to advance the LOP. When plotting a running fix in an area with a determinable current, the current should be accounted for in order to accurately determine the ship's position. By calculating the course and speed made good, which factors in the effects of the current, you can then advance the lines of position (LOP) to determine the ship's most accurate fix. This is the proper method to treat the current when plotting a running fix. The other options are incorrect because: A) Adding the drift to the ship's speed would not properly account for the current's set and effect; B) Ignoring the current would lead to an inaccurate position; and C) Applying the current set to only the second bearing would not fully incorporate its influence on the vessel's movement.
