Description

NORIE’S NAUTICAL TABLES
by Capt. A. G. Blance

This famous set of mathematical tables has been modernized and the 2007 edition contains redesigned corrections tables for the Sun, Moon and stars. In comparing Pub 229 and 249 with Norie’s cosine-haversine tables for solving the spherical triangle and ABC tables for azimuth, Noire’s has 5 place natural/log haversine and log cosine function tables that can be interpolated to the nearest .1 min of angle.

While Pub 229 and 249 are great for planning sights and quick work Norie’s one-volume size allows for extra sight reduction or sailing problems not covered by the declination range or stars listed in the 249. Plus it’s just fun to do a sight reduction using the cosine-haversine method!

Norie’s gives the observation “How far a navigator is justified in working to tenths of a minute is a matter that can be argued about indefinitely.” Since the nautical almanac gives hour angles and declinations to tenths of a minute and a modern sextant with a decimal vernier enables readings to be taken to tenths of a minute as well, it would seem only logical to use navigation tables which, with the minimum of effort, provide for the same order of precision.
