Question 1 of 2066636eea28f7522a1c51b6d0

What is the true course to steer between Stratford Shoal (Middle Ground Light) and New Haven Light, if the set and drift of the current are 048°T at 2 knots, and a southeasterly wind will cause 2° of leeway? Your engines are making turns for 10 knots.

🔍 Key Concepts

• Effect of set and drift on a vessel’s track line • How leeway from wind alters the course to steer • Using vector triangles (or current diagrams) to combine ship’s speed, current, and leeway

💭 Think About

• First, ignore current and wind: what is the approximate true course between the two lights from the chart? • If the current is setting 048°T at 2 knots and your speed through the water is 10 knots, is the current pushing you generally toward or away from your desired track? • A southeasterly wind causes 2° of leeway: does that mean you must steer into or away from the wind to stay on track?

✅ Before You Answer

• Be sure you distinguish between course made good (CMG) and course to steer (CTS) • Confirm that you are adding the current vector to the ship’s motion through the water, not to the ground track • Apply the leeway correction in the proper direction relative to the true wind direction and your intended track
