The Quick and Easy Guide to Compass Correction

George H. Reid

This guide provides all the information required to determine a ship's compass error, its true course, and how to adjust the compass.

The author describes the causes of compass error: variation, deviation, misalignment, lazy compass, frozen compass, and intermittent deviation. Beginning with the basics of magnetism, he then discusses how to apply compass error to find your true course and how to measure error by taking bearings, inland and offshore.

Captain Reid has design two quick and easy tools for celestial bearings: a Compass Corrector for bearings on the sun and a Skyclock for bearings on Polaris. Step-by-step instructions on how to swing ship, set up deviation tables, and adjust compasses are also included.

This is an indispensable reference for every sailor, regardless of size or type of vessel.
