Our Qualified Experienced Professionals have been setting the standards in the designing and surveying of yachts since 1912 and the YDSA’s worldwide network of independent specialists can be relied upon for their technical authority and professional integrity.

YDSA is authorised by the Maritime and Coastguard Agency (MCA) to do both coding and tonnage measurements for under 24m vessels.
