Question 1 of 2066636eea28f7522a1c51b2c7

When you get underway, you will take the most direct route to buoy "CBJ", while remaining west of York Spit Channel. You will be turning for 9.7 knots and estimate an average ebb of 0.3 knot during the transit. How long will it take to steam from the anchor position to buoy "CBJ"?

🔍 Key Concepts

• Speed Made Good (SMG) vs. speed through the water when there is current • Using Speed = Distance / Time and rearranging for time • Effect of an ebb current on your vessel depending on whether you are going with it or against it

💭 Think About

• From the chart, what is the straight‑line distance from the anchor position to buoy "CBJ" if you stay west of York Spit Channel? • Is the 0.3‑knot ebb helping you or opposing you on this track, and how does that change your effective speed? • Once you have your effective speed, what is the time in hours, and how do you convert the decimal part of an hour into minutes?

✅ Before You Answer

• Be sure you are using effective speed over the ground, not just 9.7 knots through the water • Confirm that the direction of ebb relative to your course is correctly applied (added to or subtracted from 9.7 knots) • Double‑check your distance measurement and unit conversion (nautical miles, knots, hours → minutes) before picking an answer
