🔍 Key Concepts

• Use the given position of Watch Hill Radiobeacon and your relative position (due north, 4.7 nm) to plot your own DR/fix on the chart • Compare each answer choice against what you can actually see/measure from that plotted vessel position (distances, bearings, charted notes) • Understand how ranges, bearings (true vs. gyro vs. compass), and depth curves (fathom curve) are shown and labeled on the chart

💭 Think About

• If Watch Hill Radiobeacon is due north at 4.7 nm, where exactly are you on the chart (lat/long or visual reference)? • From that plotted point, what are the approximate range and bearing to Fishers Island, Montauk Point Light, and Stonington Breakwater lights? • Which choice depends on specific charted relationships (like two aids on the same bearing, a precise depth contour, or a specified range line)?

✅ Before You Answer

• Make sure your plotted position places you south of Watch Hill Radiobeacon by 4.7 nm along the same meridian (same longitude) • Verify the scale of the chart and measure ranges with dividers to check 4.7–4.8 nm distances accurately • Check how gyro/compass bearings (pgc) relate to true bearings on the chart and whether any chart note shows two aids in line or on the same bearing from a given area

At 0740, Watch Hill Radiobeacon (LAT 41°18.3’N LONG 71°51.5’W) is due North (000°T) at 4.7nm. Which is TRUE?

You are on the 150 fathom curve

The closest point of Fishers Island is ranged at 4.8nm

Montauk Point Light and Montauk Point Radiobeacon are on the same bearing from your vessel as per charted information

Stonington Breakwater Light “5” and Stonington Outer Breakwater Light “4” are sighted directly in line bearing 336°pgc
