Question 1 of 2707066636eea28f7522a1c51a9e6

At 1014 you depart the entrance to Lake Montauk with light "1" close aboard. Your course is 066° per standard magnetic compass, and the speed is 8.6 knots. At 1232 your position is LAT 41°20.0'N, LONG 71°40.0'W. What is the course made good?

Question 1 of 27070

🔍 Key Concepts

• Course made good (CMG) is the actual track over the ground between your departure and arrival positions, not the course steered by the compass. • How to plot a position from latitude and longitude and then draw the line from the departure point to that fix on the chart. • Converting a measured chart course to true degrees (°T) and distinguishing it from standard magnetic compass readings.

💭 Think About

• First, think about how you would plot your starting point at the entrance light and your 1232 fix on the chart. What line connects those two points? • Once you’ve drawn that line, how do you measure its direction on the chart, and in what units (true, magnetic, or compass) is that measurement? • Is the time run or the speed needed to get the direction of the track, or are they mainly used for distance and dead reckoning checks?

✅ Before You Answer

• Make sure you are measuring the bearing from the departure point to the 1232 position, not the reverse. • Confirm that the course you read on the plotter/compass rose is in true degrees (°T) to match the answer choices. • Double-check that you are not using the steered compass course (066° per standard magnetic compass) as the course made good; instead, use the actual track line between the two plotted positions.
