You will pass through the Race at approximately the time of maximum ebb current. As you APPROACH the Race from New London, how will your vessel be set?
• Set and drift of current and how they affect your course over ground • The direction of maximum ebb current in The Race relative to New London • How a current that is not parallel to your track line pushes you to one side of the intended track
• On the chart, draw the track line from New London to your point in The Race. Then check the published direction of maximum ebb in that area—how does that arrow compare to your track? • Imagine your vessel’s heading stays on the track line, but the current is flowing in the ebb direction. Which side of the track will your actual path (course over ground) be pushed toward? • Think of set as a sideways push. Stand facing the direction of your intended course; now imagine the ebb current hitting you from the side it actually comes from in The Race—do you get pushed to your own right or left?
• Confirm from the Tidal Current Tables or current diagram what direction (in degrees true) the maximum ebb in The Race is flowing. • Compare that true current direction to the true course of your track from New London—note whether the current is coming from your port or starboard side. • Verify that you are describing the set (sideways displacement off track), not just the fact that the current is generally carrying you seaward through The Race.
