Question 218Navigation General

The correct answer is C) You should leave the buoy to port. The reason this is correct is that a green can buoy with a yellow square marking indicates a preferred channel, where vessels should pass to the green (port) side of the buoy. This is in accordance with the U.S. Aids to Navigation System, which is the standard for navigational markers in U.S. waters. The other answer choices are incorrect: A) is wrong because the buoy does not mark the end of the ICW, B) is wrong because you should not pass close aboard on either side, and D) is correct but does not fully address the meaning of the buoy's color and shape.
