Marine Surveying for Commercial Vessels

Commercial Vessel Coding Surveys

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 a Certifying Authority which must be approved by the UK Maritime & Coastguard Agency.

Mark McCrea is an IIMS Certifying Authority Registered Examiner and is authorised to carry out vessel coding and compliance examinations for certification by the IIMS.  He has approval for the following:

Construction types

  • Steel

Vessel types

  • Sport/Pleasure Motor Boats – SCV1/2
  • Sport/Pleasure Sailing Boats – SCV1/2

Stability Assessments
