🔍 Key Concepts

• Using three simultaneous bearings to fix a position on the chart • Plotting the course between your 2118 fix and the required arrival position/time • Applying the speed formula: ( \text{Speed} = \frac{\text{Distance}}{\text{Time}} ) with correct units

💭 Think About

• How do you use three bearings taken at the same time to determine a precise position on the chart? Walk through that plotting step-by-step in your mind. • Once you have your 2118 position and the destination/required-arrival point, how do you find the distance along the intended track? What tool on the chart lets you measure this? • After you know the distance and the time remaining until the required arrival, how do you convert that time to hours and plug both values into the speed formula?

✅ Before You Answer

• Confirm that you are plotting reciprocal bearings from the lights to your vessel, not the bearings from the vessel to the lights on the chart. • Double-check that the distance you measure is along the intended track line between the 2118 fix and the arrival point, not just straight between two random points. • Verify that the time difference between 2118 and the required arrival time is converted to hours and decimal hours before using the speed formula.
