Question 1 of 2066636eea28f7522a1c51b221

The following questions are to be answered using Chart 12354TR, Long Island Sound - Eastern Part, and supporting publications. Your vessel is enroute to New Haven, CT. You are proceeding at a reduced speed of 9.8 knots on a course of 243°T. Your height of eye is 45 feet and your vessel's deep draft is 33 feet. At 0930 you obtain a position from the following information: Race Rock Light bears 110°T at a range of 1.4 miles, and Goshen Point bears 330°T at a range of 3.3 miles. What are your present latitude and longitude?

🔍 Key Concepts

• Two-bearing and range position fixing on a chart using simultaneous observations • Converting true bearings and ranges from known objects into a plotted fix on Chart 12354TR • Carefully reading latitude and longitude from the chart to the nearest 0.1 minute

💭 Think About

• How do you plot two objects when you are given both a true bearing and a range to each? Think about what lines or arcs go on the chart for each object. • Once both position lines/arcs are plotted, what geometric feature represents your vessel’s position? • After finding the fix, how do you accurately transfer that point to the latitude and longitude scales on Chart 12354TR?

✅ Before You Answer

• Make sure you are using true bearings as shown (no conversion to magnetic needed). • Confirm you are measuring ranges as circles (or arcs) around the charted positions of Race Rock Light and Goshen Point, not as straight lines. • Double-check that you read latitude from the sides of the chart and longitude from the top/bottom, estimating tenths of a minute carefully before comparing with the choices.
