🔍 Key Concepts

• Difference between speed through the water and speed made good over the ground • Effect of set and drift of current on your actual course and speed made good • Using a current triangle or vector diagram to find resulting speed over the ground

💭 Think About

• Are you being helped or hindered by the current when trying to make good 150°T? How would that affect your speed made good compared to your speed through the water? • If you drew a vector triangle with your ship’s speed through the water and the current, where would the resulting vector (course and speed made good) point relative to 150°T? • Looking at the answer choices, which speeds are more reasonable for a vessel whose actual progress is being reduced or increased by current while trying to hold a particular course?

✅ Before You Answer

• Know your speed through the water (from the log or problem statement) before comparing to the choices • Determine whether the current is with you or against you along 150°T (component along your intended course) • Check that your chosen answer is consistent with whether the current should make your speed made good higher or lower than your speed through the water
