At 1412 you increase speed to make good 10.2 mph. At 1506 you have a daymark on your port beam. Which daymark is this?

🔍 Key Concepts

• Speed-Time-Distance calculations on inland waters (convert minutes to hours and use statute miles) • Understanding what it means to have an aid "on your port beam" (relative bearing vs. position on the charted track) • Using your track line and DR (dead reckoning) position between two known times to identify a specific aid to navigation

💭 Think About

• From 1412 to 1506, how much time has passed in hours, and how far would you travel at 10.2 mph in that time? • If you plot your course and distance from your 1412 position, where would your DR position be at 1506, and which aid would lie roughly abeam to port of that position? • Looking at the chart, which of the listed lights/daymark would fall on the port side of your track at about that DR point rather than ahead, astern, or to starboard?

✅ Before You Answer

• Carefully convert 54 minutes to hours before multiplying by 10.2 mph • Plot the DR track from your last known fix at 1412 along the correct course and speed before checking the aids • Verify which aid is approximately 90° to port of the DR position at 1506, not the one closest ahead or astern on the track
