With the YDSA Certifying Authority, you have a choice of Coding Surveyors. Our Coding Surveyors are selected from our membership of experienced Marine Surveyors, meaning they have proven experience in the industry. They are not employees and you are free to choose any YDSA Coding Surveyor from around the UK and overseas.

Coding Surveyors are divided into two levels, according to their qualifications and experience:

  • Level 1: Coding vessels in all categories; carrying 16 or more persons; lifting/towing; carrying more than 1 tonne of cargo; and Pilot Boats.
  • Level 2: Coding vessels up to Category 2 not requiring a Stability Information Booklet.
