ADMIRALTY Digital Sailing Directions

The ADSD test phase closed on 30 September, supported by valuable feedback from more than 76 completed surveys. This insight is helping us refine ADSD to ensure it delivers real value to passage planning professionals worldwide.

ADSD is being developed to provide:

  1. Smarter access to trusted information – with intuitive search, filtering and bookmarking.
  2. Greater confidence at sea – with regularly updated content that crews can depend on.
  3. Improved efficiency – saving valuable time in both planning and decision-making.

With ongoing refinement, ADSD is evolving into the intuitive passage planning tool to support safer, more efficient and more sustainable voyages.
