The Catalogue of ADMIRALTY Charts and Publications (NP131), 2026 Edition is the UK Hydrographic Office's complete listing of ADMIRALTY paper charts and nautical publications worldwide, organised by region with graphical indexes.

Edition at a glance

What's inside

• Every ADMIRALTY chart and publication, listed by region with a composite index
• Title, scale and coverage for each chart
• Maritime security charts and other special charts and diagrams
• ADMIRALTY distributors worldwide
• How charts are numbered, sized and kept up to date with Notices to Mariners

How to use it

Find your area on the graphical index, read off the chart numbers that cover it, then check each chart's title, scale and limits in the listings. The same approach works for nautical publications such as Sailing Directions, Lists of Lights and Tide Tables.

Keeping it current

Changes after publication are announced in the weekly ADMIRALTY Notices to Mariners, so the catalogue and the notices are used together.

Who uses it

Navigating officers, chart agents and ship managers who need to choose, order and keep track of ADMIRALTY charts and publications.
