🔍 Key Concepts

• Effect of set and drift on speed made good and course over ground • Relationship between engine speed (speed through the water) and speed over ground when a current is helping or opposing • Using a time–speed–distance triangle or table to adjust ETA after applying current corrections

💭 Think About

• Is the current generally helping your motion toward buoy "W" or setting you more sideways/against it, based on its direction 215°T compared to your track? • How does a 0.5‑knot current affect your overall speed made good if your engine speed is 7.5 knots—will your speed over ground be more, less, or about the same as 7.5? • Once you know your speed over ground, how do you compute the time to run the remaining distance to a point 0.5 mile south of buoy "W" and then convert that running time into a clock ETA?

✅ Before You Answer

• Be clear on whether you are using speed through the water (STW) or speed over ground (SOG) in your time–distance calculation • Make sure you are using true directions (°T) consistently when judging whether the current is helping or opposing your course • Double‑check your final ETA by recalculating: Distance ÷ SOG = Time, then add that time correctly to your departure time or last known time fix
