More routes, more ports
The ADMIRALTY Vector Chart Service (AVCS) provides the widest official ENC coverage available, enabling ships to navigate on ECDIS for the entirety of most major routes on a single chart service. This coverage includes 4,000 of the biggest ports worldwide, of which we offer unique coverage for over 70.
Ongoing safety and compliance
All AVCS customers are supplied with weekly electronic updates via internet download, email or disc - ensuring that bridge crews and shore-based teams have access to complete and up-to-date information. These electronic updates reduce time and effort spent making manual updates to paper charts, minimise the risk of human error and help to ensure compliance with Flag and Port State requirements.
AVCS contains accurate maritime data that meets industry S-63 and S-57 formats
All ships using AVCS on board receive a UKHO certificate. This certificate can be used for local inspections and confirms that all Electronic Navigational Charts (ENCs) in AVCS satisfy the chart carriage requirements of SOLAS Chapter V.
AVCS meets the latest mandated data protection standard from the International Hydrographic Organization (IHO), which helps to reduce the risk of both data piracy and the distribution of unofficial, dangerous data to mariners.
ADMIRALTY Information Overlay, unique extra navigational data
The ADMIRALTY Information Overlay (AIO) aids navigators at the crucial passage planning stage.
It contains ADMIRALTY paper chart Temporary and Preliminary Notices to Mariners (T&P NMs) where the information is not encoded into the underlying ENC. It also contains ENC Preliminary Notices to Mariners (EP NMs), which highlight navigationally significant differences between ENCs and ADMIRALTY paper charts.
AIO can be displayed as a single layer on top of ENCs on the majority of ECDIS currently being sold, and also on back-of-bridge software. All AVCS customers receive the unique AIO at no extra cost.

Purchase options that suit you
For maximum convenience, AVCS ENCs can be ordered in predefined transit, regional or port folios (groupings of ENCs). New ENCs are automatically added as soon as they become available, ensuring your ships always have the latest data. You can also combine AVCS folios with your choice of individual ENC charts for unrivalled coverage and flexibility.
Alternatively, all ENCs can be bought on an individual, chart-by-chart basis for precise coverage and voyage flexibility. Simply buy the licences to unlock the charts needed for a voyage, when and for as long as they are needed. Most ENC-issuing producers allow durations of 3, 6, 9 or 12 months.
To offer further flexibility in navigation, Pay As You Sail (PAYS) subscriptions are available for AVCS. A PAYS subscription automatically purchases a 3 month licence for each ENC under the vessel's track, so you only pay for those used during the passage. The vessel is also supplied with a worldwide permit set that allows full use of ENC data for planning purposes.
