Question 1 of 2707066636ee928f7522a1c51a4f2

You are underway on course 315°T at 14 knots. The current is 135°T at 1.9 knots. What is the speed being made good?

Question 1 of 27070

You are underway on course 315°T at 14 knots. The current is 135°T at 1.9 knots. What is the speed being made good?

🔍 Key Concepts

• Current vector vs. ship’s speed through the water • Using a vector triangle or current table to combine course and set/drift • Difference between speed through the water and speed made good over the ground

💭 Think About

• Is the current helping you (more or less in the same direction), opposing you, or crossing your track? How would that affect your speed made good compared with 14 knots? • If your course is 315°T and the current is 135°T, how are those two directions related on a compass rose (same, opposite, or something else)? • When you draw the vectors tip‑to‑tail, what does the length of the resultant vector represent in this problem?

✅ Before You Answer

• Sketch the ship’s vector and the current vector to scale with correct directions before judging which answer is reasonable. • Confirm whether the current should make your speed made good greater than, less than, or equal to 14 knots before looking at the choices. • Check that the numerical difference between 14 knots and your final speed is consistent with a relatively small current of 1.9 knots (not a huge change).
