e-NP Sailing Directions

 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.

Carriage compliance

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
