Q

Which type of current will have the greatest effect on the course made good for your vessel?

🔍 Key Concepts

• Set and drift of a current and how they affect a vessel’s actual track over the ground • Difference between speed made good and course made good • Vector addition of ship’s motion through the water and current direction (current with, against, or across your heading)

💭 Think About

• Think about which current direction will change the vessel’s heading over the ground the most, not just its speed. • If your ship is pointed north, which direction of current (north, south, east, or west) will push you farthest away from the line you intend to follow? • Compare how a current directly ahead/astern vs. a current from the side will appear on your track line on the chart.

✅ Before You Answer

• Focus on course made good over the ground, not time en route or fuel used. • Visualize or sketch simple vector diagrams for each choice: ship’s track through the water and current direction. • Verify which option causes the largest sideways displacement from your intended track line.
