Q

At 0946, the radar range to Hammonasset Point is 2.5 miles. The range to the eastern most point of Falkner Island is 3.3 miles, and the range to Horton Point is 10.1 miles. What is your position at 0946?

🔍 Key Concepts

• Using radar ranges to three fixed charted objects to obtain a three-range fix (circles of position) • Correctly identifying Hammonasset Point, the easternmost point of Falkner Island, and Horton Point on the chart • Measuring ranges on the chart with dividers or a compass and plotting circles from each known point

💭 Think About

• How do you transfer each radar range from the vessel to the charted object and represent it graphically on the chart? • What happens on the chart where all three range circles from Hammonasset Point, Falkner Island, and Horton Point intersect? • Once you find that intersection point, how do you read the latitude and longitude precisely enough to distinguish between the answer choices?

✅ Before You Answer

• Be sure you are using the correct features (Hammonasset Point, easternmost point of Falkner Island, Horton Point) and not nearby aids or points with similar names • Double-check your range scale when setting dividers so that 2.5, 3.3, and 10.1 miles are plotted accurately • Carefully read latitude from the side scale and longitude from the bottom/top scale, paying attention to tenths of minutes to match the choices
