Mini ISM


The UK Maritime & Coastguard Agency (MCA) Large Yacht Code requires all commercial vessels under 500GT to maintain a Mini-ISM system. It is strongly recommended that all yachts under 500GT maintain a Mini-ISM wherever possible.

A Mini-ISM is a safety management system based on the ISM Code but tailored specifically to the needs of commercial yachts over 24 meters and under 500GT which  otherwise, under international maritime law, have to comply with a full ISM system.

All commercially operated yachts under 500 gross tonnage must design and implement a SMS which adheres to all regulations and standards issued by international bodies such as the International Maritime Organisation (IMO) as well as local governments and private bodies such as classification societies and flag states.

The ISM Code stands for the International Safety Management Code which in turn is short for the International Management Code for the Safe Operation of Ships and for Pollution Prevention as adopted by the International Maritime Organisation (IMO). The ISM Code provides an international standard for the safe management and operation of ships and for pollution prevention.

The Support4yachts ISM and checklists are delivered as a web application as either standard or bespoke documents that allow approved users the ability to control vessel or fleet safety management systems anywhere, including in offline mode – synchronising with the shore based server when the vessel reconnects to the Internet. This offers a structured, paperless and auditable way to demonstrate due diligence in managing the owner’s valuable asset and safeguarding the lives of those on-board.  Alternatively Support4yachts can supply the Mini-ISM as a editable pdf.

The purpose of a Mini-ISM is to:

- Promote and ensure safety at sea for the yacht's crew and guests and third parties

- Avoid damage to the yacht
