Crews can also use the software to calculate and view safe clearances based on a ship's draught, masthead and under-keel clearance allowance.

Compliance

Approved by the Flag States of over 80% of ships trading internationally, ATT provides the same level of compliance as traditional ADMIRALTY paper-based publications, for ships trading under these Flag States. Where we are aware that a Flag State Authority (FSA) has issued documentation on the acceptance of UKHO's digital nautical publications or provided guidance on their use, we have listed it in the table below.

Important notes:​ ​​​

  • FSAs who accept UKHO's digital nautical publications, but have not issued any specific requirements, may not be listed​​

  • If it is not clear whether a FSA accepts UKHO's digital nautical publications as satisfying carriage requirements then shipping companies should contact their FSA or the appropriate RO​
