Assuming no current, at what time can you expect to be abeam of Townshend Ledge Lighted Buoy?

🔍 Key Concepts

• Speed–Time–Distance relationship:

\text{Time} = \frac{\text{Distance}}{\text{Speed}}

• What "abeam" means in piloting (bearing about 090°/270° relative, i.e., roughly off your beam) • Effect of "no current" on your speed over ground (SOG) vs. speed through the water

💭 Think About

• From earlier in the problem, determine the vessel’s speed and the distance from your last known time/fix to the point where you will be abeam of Townshend Ledge Lighted Buoy. • Use the speed–time–distance formula to find how many minutes it takes to travel that distance, then add that to your starting time to get the expected abeam time. • Think about what "no current" allows you to ignore in your calculation and how that simplifies your ETA.

✅ Before You Answer

• Be sure you are using nautical miles for distance and knots for speed so the units match. • Verify exactly from which time/fix the question wants you to measure the run to the abeam position. • Confirm on the chart where the vessel is when the buoy will be abeam (on the beam, not ahead or abaft the beam) before computing the time.
