Question 1441Navigation General70% to pass
In illustration D051NG below, why was the position labeled "E" plotted?
AI Explanation
The correct answer is D) a dead reckoning position is plotted for each speed change.
The key reason is that in navigation, it is standard practice to plot a dead reckoning position after each speed change, in order to accurately track the vessel's course and position. This allows the navigator to account for changes in speed and update the vessel's estimated position accordingly. Plotting a position at "E" after a speed change is the correct procedure, as outlined in the regulations and best practices for coastal navigation.
The other options are incorrect because: A) the question does not specify the vessel's fixed position at 1145, B) a running fix requires taking multiple bearings or position lines, and C) while a DR position is often plotted after course changes, the question specifically asks about speed changes.
