Please note: When selecting any digital product to the shopping cart, the person placing the order accepts the fact that once an order is placed, it cannot be refunded as licences are issued by the UKHO on a non-refundable basis.
Before purchasing e-NP's you will need to have the e-NP software downloaded and inform us of your username details so we can link the licence to your account. Please contact us for further information or to discuss before you place your order.
e-NPs are e-book versions of our world-leading paper-based Nautical Publications. They allow bridge crews to speed up the updating process and give them easier access to information they need.
Fast and accurate Notices to Mariners updates
Small, weekly NM update files can be regularly downloaded via the internet and accurately added to e-NPs in seconds - far more easily and quickly than with paper-based products. This allows bridge crews more time to focus on other important duties and gives decision makers more confidence on the bridge. These updates are also available on a quarterly DVD.
Easy access to important information with ADMIRALTY e-Reader
e-NPs are displayed using the ADMIRALTY e-Reader. This is a specifically designed, easy-to-use reader software developed by the UKHO, and is supplied as part of the service at no extra cost. ADMIRALTY e-Reader also has a simple search function that allows users to access information easily and quickly.
All e-NPs contain the same official information as their paper equivalents, and most Flag States have approved them as SOLAS carriage-compliant. e-NPs can also aid inspections by clearly showing when a publication was last updated.
Publications currently available as e-NPs include:
ADMIRALTY Sailing Directions
Often known as “Pilots”, ADMIRALTY Sailing Directions meet SOLAS carriage-compliance requirements and provide essential information during port entry and coastal navigation.
They are designed to be used alongside the range of ADMIRALTY navigational charts on all classes of ships at sea. Sailing Directions provide worldwide coverage and are split into 74 volumes, so you only need to buy the volumes you need. Click here for a PDF coverage diagram of all Sailing Directions.
Each volume contains:
- Information on navigational hazards, buoyage, pilotage, regulations, port facilities and guides to entering major ports

- basic meteorology

The Nautical Almanac (NP314)
