Question 1787Navigation General

70% to pass

You are steering a southerly course, and you note that the chart predicts an easterly current. Without considering wind, how may you allow for the set?

A Head your vessel slightly to the left
B Head your vessel slightly to the right
C Decrease your speed
D Increase your speed
AI Explanation

The correct answer is B) Head your vessel slightly to the right. When navigating with a predicted easterly current, the vessel will be set to the east of the intended course. To compensate for this set, the vessel should be headed slightly to the right (or west) of the desired southerly course. This will allow the current to push the vessel back onto the intended track. Heading to the left (option A) would compound the easterly set, while decreasing (option C) or increasing (option D) speed would not directly address the issue of the current's influence on the vessel's course.
