The Coefficient of Safety in Navigation (Classic Reprint) - Softcover

Inhaltsangabe

The Coefficient of Safety in Navigation explains how measurement errors and safety margins affect a ship’s position at sea.

This historical study analyzes the limits of chronometers, the reliability of observations, and the real-world uncertainty sailors face when determining longitude and course. The book frames navigation as a practical problem, balancing theory with data from wrecks, chronometer tests, and voyage records. It shows how small errors can grow into large deviations, and it offers methods sailors can use to improve accuracy without chasing false precision.

• How average error and safety coefficients are calculated and interpreted
• What chronometer tests reveal about movement, temperature, and seaworthiness
• How sailors use the lead, soundings, and dead reckoning to fix position
• Common compass deviations and the impact of currents and leeway on navigation
