Luis Mederos is a Uruguayan sailor and navigator known for his practical, clear, and rigorous approach to celestial navigation. Unlike many academic texts that drown the reader in spherical trigonometry, Mederos’s work—most famously his book Navegación Astronómica —focuses on step-by-step procedures, real-world examples, and the reduction of complex concepts into actionable routines.
