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.

Select a location by UK, Europe or Rest of World and then select your required region/country. Surveyors travel widely and the address listed is their main office(s).

To expand the search results to include surveyors who have told us they travel to your selected region/country, tick the option "Expand to include those who work in this region" and click Search/Filter Results again.

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.
