Celestial Navigation
註釋NAVIGATION & SEAMANSHIP. Guiding a craft using one of the oldest of the mariner's arts-celestial navigation As romantic--sounding as sailing to Tahiti did centuries ago, using the sun, moon, planets, and stars to guide one's boat on the seas is enjoying a comeback. For those who do not wish to be caught short when modern technology fails on board, knowing how to chart a path with the aid of a sextant is an essential navigating skill. In Celestial Navigation, veteran yachtsman, Tom Cunliffe, reveals how any boat owner can master this seafaring technique, without complex mathematics, using his simplified approach. Readers begin with a sound foundation of basic concepts and definitions, before moving on to the hardware-the sextant and how to use it. Within a few pages, you'll be working out your latitude from a noon sight, and learning how to plot a position from observing the sun, planets, moon or stars-or wherever you may be on the world's oceans.
