The 1988 almanac is split into three main sections. The daily pages (two days per spread) contain the GHA and Dec for the Sun, Moon, Venus, Mars, Jupiter, Saturn, and 57 navigational stars.
For example: On July 14, 1988, at 14:00 GMT, you would look up the Sun’s GHA and Dec, then interpolate for the 22 minutes and 45 seconds of your actual sight time.

Owning a yacht built in the late 1980s often goes hand-in-hand with a love for period-correct gear. Owners of vessels like the O’Day 34 or the Hunter 33 Legacy want to sail their boat as it was sailed originally. Using a 1988 almanac with a 1988 sextant on a 1988 boat creates an authentic experience.
The 1988 Nautical Almanac—specifically the joint publication by the US Naval Observatory (USNO) and the UK Hydrographic Office—is structurally identical to the almanacs used today. Key components included: The 1988 almanac is split into three main sections
For the year 1988, navigators had to account for specific planetary phenomena that occurred that year, such as the positions of Venus and Mars as they shifted relative to Earth, as well as the specific equations of time for the Sun.
Researchers reconstructing voyages or analyzing historical logs from 1988 need the precise celestial data from that year to verify the positions recorded by captains of that era. For the year 1988, navigators had to account
A Nautical Almanac is an annual publication that provides the positions of celestial bodies—such as the Sun, Moon, planets, and specific navigation stars—for every hour of the year. It is the essential database required to perform celestial navigation.
Using a sextant to measure the angle of a celestial body above the horizon is only half the battle. To determine a line of position, the navigator must know exactly where that celestial body was located in the heavens at that specific moment in time. The almanac provides the Greenwich Hour Angle (GHA) and Declination needed to perform these calculations.
Maritime accident investigators or family historians occasionally need to reconstruct a voyage. If a sailor’s logbook from 1988 records "Sun sight at 14:22 GMT – assumed position 40°N, 70°W," the only way to verify that calculation is with the corresponding 1988 almanac.
Celestial navigation is a perishable skill. Maritime academies and amateur sailors often practice with historical almanacs to test their proficiency. Using a 1988 almanac allows a student to practice the "math" of navigation without the confusion of modern variable data. It provides a static dataset where answers can be checked against known historical logs.
