🔍 Key Concepts

• Use your vessel’s true course and speed to find how far you travel between the two bearings • Convert the lighthouse’s true bearings to relative bearings from your bow (based on your 267°T course) • Remember the standard distance off by bearings triangle: your run between bearings and the two lines of bearing form a right‑angle or oblique triangle

💭 Think About

• What is the time between 0433 and 0452, and how many miles do you travel at 22 knots in that time? • Once you know how far you ran, where do those two bearing lines fall relative to your heading (ahead, on the beam, abaft the beam)? • How can you use the change in relative bearing and the distance run to form a triangle whose perpendicular side is your distance off at the second bearing?

✅ Before You Answer

• Be sure you convert from true bearings to relative bearings correctly: Relative = BearingT − CourseT (adjust into 0°–360°) • Confirm you are using nautical miles and hours when applying ( \text{Speed} = \frac{\text{Distance}}{\text{Time}} ) • Before you pick an answer, check that your computed distance off is less than your run between bearings and is consistent with the object passing toward your beam and then aft.
