70% to pass

Diagram for USCG Navigation General: Your vessel is entering port and you have steadied up on a range, dead ahead,...
A Maintain heading, keeping the range dead ahead
B Alter heading to the left
C Increase speed
D Alter heading to the right
AI Explanation

The correct answer is B) Alter heading to the left. When a range appears as shown in illustration D047NG, with the range marker slightly off to the right of the vessel's centerline, it indicates that the vessel is to the right of the range. To correct this and return to the range, the vessel should alter heading to the left to bring the range marker back to the center. Maintaining the current heading (option A) or increasing speed (option C) would not resolve the vessel being off the range. Altering to the right (option D) would take the vessel further off the range.
