All UK vessels in commercial use up to 24 metres load line length, which go to sea are required by law to comply with one of the Maritime and Coastguard Agency (MCA) Small Craft Codes.
Vessels that meet the MGN 280 code or one of the other specialist small craft codes are issued with Certificates by the IIMS Certifying Authority, which is approved by the UK Maritime & Coastguard Agency.
IIMS Certifying Authority Registered Examiners are authorised to carry out vessel coding and compliance examinations for certification by the IIMS and are shown in the IIMS Certifying Authority directory on this site.
The IIMS uses the “The Harmonised Code MGN 280” for vessel coding covering:
• Sailing charter vessels, both skippered and bareboat
• Motor charter vessels including angling and dive boats
• Motor vessels carrying up to 12 passengers
• RIBs operating commercially
• Pilot boats
The requirements for the use of each vessel are considered and the category approved will depend upon the nature of its operations, distance from a safe haven, limiting weather and whether overnight passages are to be undertaken.
So which category is right for you and your vessel?
Category 6: To sea within 3 miles from a nominated departure point(s) named in the certificate and never more than 3 miles from land in favourable weather and daylight.
Category 5: To sea within 20 miles from a nominated departure point named in the certificate in favourable weather and daylight.
Category 4: Up to 20 miles from a safe haven in favourable weather and in daylight.
Category 3: Up to 20 miles from a safe haven.
Category 2: Up to 60 miles from a safe haven.
Category 1: Up to 150 miles from a safe haven.
Category 0: Unrestricted service.
How to choose an IIMS Certifying Authority Examiner

Transferring your vessel(s) to the IIMS Certifying Authority
If you are already registered with another Certifying Authority, you can transfer to the IIMS at no extra cost should you so wish. In that event, you as the vessel owner must write to your current Certifying Authority and ask them to transfer the documents to the IIMS.
You may wish to do this for commercial or practical reasons, or because you wish to change coding examiner to one registered and approved by the IIMS.
