Question 1799Navigation General

The correct answer is B) One. To plot a running fix, only one fixed object is needed. A running fix is a method of determining a vessel's position by using multiple lines of position obtained at different times. By using a single known fixed object, such as a landmark or navigational aid, the vessel's position can be plotted as it moves over time. The other options are incorrect because more than one fixed object is not required to plot a running fix.
