The ADMIRALTY Vector Chart Service (AVCS) is the world’s leading official digital maritime chart service, with over 17,000 official Electronic Navigational Charts (ENCs) to help bridge crews navigate safely and efficiently whilst meeting flag and port State requirements.

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.

Key features of AVCS include:

  • Global maritime ENC coverage with more routes and ports than any other competing service.
    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.
  • Unique ADMIRALTY Information Overlay (AIO) for additional passage planning information.
    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.
