Question 1 of 2066636eea28f7522a1c51b21e

The following questions are to be answered using Chart 12354 TR, Long Island Sound - Eastern Part, and supporting publications. You are turning for 12.5 knots and on a course of 255°T. Your vessel's deep draft is 24 feet. Gyro error is 3°E. Use 14°W variation where required.

DEVIATION TABLE Magnetic Heading Deviation 240° 2°W 255° 0° 270° 2°E 285° 4°E

At 2216 your position is LAT 41°16.0'N, LONG 72°08.0'W. Which statement is TRUE?

🔍 Key Concepts

• Gyro to true and true to gyro conversions, including gyro error and variation • Using Chart 12354 TR soundings and fathom/feet conversions to estimate depth near the given position • Bearing and distance checks from your plotted position to nearby lights and sector limits (Little Gull Island Light and New London Harbor Light)

💭 Think About

• First, carefully plot LAT 41°16.0'N, LONG 72°08.0'W on Chart 12354 TR. From that exact position, check your proximity to the shoreline and depth contours—what depth band are you actually in? • From your plotted position, take a bearing and distance to Little Gull Island Light. Does the charted bearing and range from your fix match the statement in any choice? • Check the sector limits and ranges for New London Harbor Light in the Light List or on the chart. From your plotted position, are you inside the red sector limits and within its effective range, or still outside?

✅ Before You Answer

• Confirm your plotted fix is accurate by cross-checking latitude on the side scale and longitude on the top/bottom scale—no estimating off-scale. • Verify depth units: are the soundings in feet or fathoms, and is there any note about reduction to mean lower low water (MLLW)? Convert if necessary before comparing to the statement about 40 feet. • When evaluating the demarcation line statement, locate the Colregs Demarcation Line on the chart and compare its orientation and position with your course of 255°T from the plotted fix—would you actually cross it if you keep that course?
