The Mariner's Yearly Reference

Published annually by Brown, Son and Ferguson, this almanac is a long-standing reference for the merchant navy, yacht owners, shippers and shipping offices. Revised each year and released in October ahead of the following year's use, it brings together astronomical data for navigation, nautical tables and calculation methods, and tide predictions for British and international waters.

Inside you'll find coastal courses and distances around the British Isles, worldwide port-to-port distance tables, details of lights, beacons and buoys, and technical guidance on trim, draft and displacement calculations. The 2026 edition also carries updated information on offshore wind farms and installations around the UK coastline, along with GPS rhumb-line distance data, great circle sailing methods and practical pilotage notes.
