Question 1 of 2066636ee928f7522a1c5197ac

The following questions are to be answered using chart 12221 TR, Chesapeake Bay Entrance, and supporting publications. Your vessel is enroute from New York, NY, to Baltimore, MD. Your vessel's draft is 29 feet, and your height of eye is 54 feet. Your present course is 206°T and your speed is 18 knots. Use 10°W variation where required. At 0705 your position is Latitude 37°20.8' N Longitude 75°29.9' W. If a northwesterly breeze is causing 3 degrees leeway what is the true course to steer in order to pass Hog Island Lighted Bell Buoy "12" at a distance abeam of two miles?

🔍 Key Concepts

• Leeway and how wind direction (northwesterly) pushes your vessel sideways relative to your heading • Plotting a track on Chart 12221 TR to pass a fixed mark (Hog Island Lighted Bell Buoy "12") at a specified closest point of approach (CPA) abeam • Difference between course steered (heading) and course made good (track over the ground)

💭 Think About

• From your 0705 position, plot the line that gives you a 2‑mile abeam CPA to Buoy "12". What true course along the chart actually achieves that geometry? • Given a northwesterly breeze, is the sideways push setting you to the left or to the right of your intended track when you are heading generally southwest? • Once you know which way the wind pushes you, should you steer into the wind or away from the wind to keep your track where you want it, and by how many degrees based on the leeway given?

✅ Before You Answer

• Be clear which direction a northwesterly wind blows toward on the chart and how that relates to your heading of about 200°T. • Verify whether the 3° leeway should be added to or subtracted from the desired track to get the true course to steer. • Confirm you are working entirely in true directions on the chart (and only bring in variation if you convert to compass or magnetic) before comparing with the answer choices in true.
