ENSIGN – Large Yacht Services

The Maritime and Coastguard Agency (MCA) is a world leading maritime administration and the originator of the Large Commercial Yacht Code. Ensign is the Large Yacht Survey unit of the MCA.

Large Commercial Yacht Code (LY3) 

  • LY3 has been developed with industry to keep up with developments and amendments which have subsequently taken place with the international conventions for which the codes provide an alternative means of achieving compliance, more suited to commercial yachts.
  • LY3 published August 2012, will assist designers and builders preparing new designs.
