Reeds Astro Navigation Tables 2020

The established book of annual astro-navigation tables compiled specifically for the needs of yachtsmen. Reeds Astro Navigation Tables 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. Now updated with eight extra pages and an improved layout, this book, together with a sextant, will enable sailors to navigate confidently and safely when out of the sight of land.. The book continues to feature the well-received additions of the past couple of years, including 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. There is plenty of space for making notes and calculations.
