What is the ISM Code and does it apply to my yacht?
The ISM Code (International Safety Management Code) is an IMO standard requiring commercial vessels of 500 GT and over to implement a documented Safety Management System. Private yachts not engaged in trade are outside SOLAS and exempt, but flag states may apply national equivalents.
The ISM Code, made mandatory by SOLAS Chapter IX, requires operators to implement a Safety Management System (SMS) covering safety policies, emergency procedures, and maintenance records.
For commercial yachts: vessels carrying more than 12 passengers or vessels of 500 GT and over operating internationally must comply. The operator must hold a Document of Compliance (DOC) and each vessel must have a Safety Management Certificate (SMC).
For private yachts: yachts used exclusively for pleasure and not engaged in trade are outside SOLAS, so the ISM Code does not apply to them. Commercial yachts under 500 GT are a separate case: the Red Ensign Group Yacht Code requires those of 24 meters and over to run a safety management system without full ISM certification.
Practically: even non-ISM yachts benefit from SMS-style documentation. Port State Control inspectors expect to see emergency procedures, maintenance records, and drill logs regardless of formal ISM applicability.
