Reeds Astro-Navigation Tables is an established book of annual astro-navigation tables compiled specifically for the needs of yachtsmen. It contains all the information the ocean-going sailor needs (without the bulk) in order to navigate by the sun, moon, planets, and stars, using tables devised by practical ocean navigators. This book, together with a sextant, will enable sailors to navigate confidently and safely when out of the sight of land.
This year the book has been expanded and now includes forms to help determine True Altitude (for the sun, planets, and stars), Calculated Altitude (using the versine formula), and Azimuth (using the ABC Tables), as well as a pro forma for calculating Intercept. With sixteen extra pages, the layout has been improved and there is now plenty of space for making notes and calculations.
