Classification rules are developed to assess the structural strength and integrity of the essential components of the ship's hull, the reliability and function of propulsion, steering systems, power generation, and any other equipment installed on board that helps ensure the ship's essential functions. In addition to this "third party" inspection, the classification societies perform statutory duties on behalf of the major flag administrations in accordance with specific delegation agreements signed with each government. Commercial yacht means a commercially used (e.g., chartered) motor vessel for sport and recreation that does not carry cargo or more than 12 passengers.

The main classification societies operating in the yacht sector include: American Bureau of Shipping, Bureau Veritas, DNV GL, Lloyd's Register and RINA.

Yachts under 24m

The mandatory requirements for boats under 24m are very low. For most flag states, an approval inspection and a tonnage survey, which is carried out by an authorized expert, are sufficient. The only binding international conventions are those dealing with the protection of the marine environment: MARPOL and the Anti-fouling Systems Convention. The Antifouling Systems Convention aims to eliminate the harmful substances contained in antifouling paints for ships from the marine environment.

Bering builds even its yachts under 24m to the highest standards and uses only classified materials and equipment. This means that in the future Bering Explorers will only be built to commercial class.
