Master the method of finding longitude at sea with time-keepers and practical observations
This edition presents a clear, step-by-step approach to using a time-keeper to determine longitude. It explains the ideas behind longitude, how to apply a watch to the task, and how to measure the rate of a time-keeper in order to pinpoint mean time at sea.
Designed for sailors and students of navigation, it also outlines the advantages and limits of time-keeper methods, and contrasts them with observations of fixed stars and solar altitudes. The text emphasizes practical procedures, including quick calculations and the reasoning behind daily observations at sea.
- How to use a time-keeper to find longitude and why rate matters
- Simple, repeatable methods for deriving daily gains or losses in a watch
- Alternative approaches using fixed stars and solar altitude with Hadley’s quadrant
- Tables of equations and practical examples to guide practice
Ideal for readers of maritime history and navigation who want a grounded, hands-on look at early methods for determining position at sea. This edition supports curious minds and professionals seeking a historical perspective on practical astronomy at sea.
