When does the yacht need to comply with the Minimum Safe Manning Document?

If the vessel maintains a Certificate of Code Compliance (LY2/LY3) the vessel should maintain the manning levels as indicated in the Minimum Safe Manning Document. If it is privately operated the yacht can replace the Certificate of Code Compliance with a Statement of Compliance if it does not wish to comply with the manning requirements. Please also see Shipping Notice 02/21012 regarding Manning for yachts carrying 12 passengers or less on the commercial part of the register as "Commercial Vessels" or which are engaged in trade.
