Which statement best describes course over ground?

• A. The ship's heading only.
• B. The ship's actual path over the earth, including effects of current.
• C. The distance to shore.
• D. The ship's speed over the earth.

Answer: (B)

Understanding course over ground means recognizing the ship’s actual path over the Earth’s surface, not just the direction the bow is pointing. This path includes the effects of currents and drift from wind, so the route you actually travel can differ from your heading or from the line you intended to follow. If the wind or current pushes you to the side, your course over ground shifts accordingly, even though you may be steering in another direction. In contrast, heading is simply the direction the bow points, which may be different from the path you end up tracing over the ground. Speed over ground tells you how fast you’re moving relative to the Earth, but it doesn’t describe which direction you’re moving. The distance to shore is a separate measure and not a description of movement over the ground.
