Paperback. Condizione: New. Print on Demand. This book is a comprehensive resource for determining the deviation of a ship's compass caused by iron in the vessel's construction. It was written at a time when wooden ships were being replaced with iron ones, and the magnetic compasses used for navigation were prone to errors due to the magnetic fields generated by the iron hulls. The text delves into the history of compass deviation and its impact on navigation, providing practical methods for calculating and correcting for these deviations. It discusses the various factors that can affect compass accuracy, including the ship's heading, latitude, and the presence of magnetic materials on board. The book's significance lies in its contribution to the development of accurate and reliable navigation techniques. By providing a thorough understanding of compass deviation, it enabled sailors to navigate more effectively and safely in the age of iron ships.
