Yacht Classification

Rules and Regulations for yachts
Building upon its Greek maritime heritage, INSB Class has developed dedicated Rules & Regulations for sailing boats and motor yachts classification, either under construction or in service, in compliance with appropriate technical standards.
INSB Class “Rules for the Classification and Construction of Yachts” support all phases of the yacht’s lifespan and are applied for assessing yacht’s hull strength and integrity, propulsion and steering systems, electrical installations, pollution & fire fighting protection systems as well as other essential operational components.
Where required and with the aim to complement a consistent classification process, contents from other parts of INSB Class Rules are referenced.
A yacht remains in compliance with the INSB Class rules when subjected to periodic classification surveys as defined by the rules and found to demonstrate compliance with the applicable requirements.
Apart from the normal classification process, INSB surveyors may attend yacht retrofits or modifications to determine that the work performed returns the unit to a condition that conforms to the INSB Class Yacht Rules.
By maintaining a yacht in class – either used for recreational purposes or fully commercial- may raise asset value, enhance operations, satisfy insurance policies and complement re-sale purposes.
Compliance

Compliance with flag state codes
INSB Class is recognized by leading Ship Registers involved in the registration of yachts to deliver on their behalf survey, assessment & certification of compliance with pertinent Flag States dedicated yacht codes requirements including:
- Greece,
- St. Vincent and the Grenadines,
- Barbados,
- Belize,
- Cook Islands,
- Jamaica
- Marshall Islands
as well as additional Flag Administrations.
Many Flag States require specific safety standards to be followed for the survey and certification of Pleasure and / or Charter Yachts engaged in commercial trade.
Such standards have been embedded into each Flag State’s developed Safety Code of Practice for Pleasure / Charter Yachts engaged in Commercial Trade which sets standards of safety and pollution prevention, appropriate to the size and use of the yacht.
Typically, these Flag State Codes requirements are either set by the applicable International Conventions or are equivalent standards when it is not reasonable or practicable to comply with provisions according to the relative international conventions.
Applicable requirements for safety include: stability, safety construction, safety equipment (fire fighting and lifesaving appliances), radio communication, navigation equipment and safe manning and for protection of the marine environment from pollution.
