Certification Control Form

The class rules allow pigmentation of resins used in the moulding of hulls and the difficulty in examining the interior of many hulls, the declarations required on the Certification Control Form require the builder of the hull to declare that the materials used in the construction of the hull / boat are in compliance with the class rules. The simplest way to deal with the Declaration would be for the builder to include a pre-signed Certification Control form with the boat at delivery to the owner. Alternately if a completed boat is not being delivered to provide a declaration that to the best of his knowledge the components supplied meet the requirements of the class rules.

The Certification Control Form remains the only form required to be sent to and retained by a NCA as the result of a successful certification control. The method of storage is the NCA’s decision.

IOM Certificate Template

Any skippers looking to obtain a IOM Certificate should in the first instance contact their World Council Member within their individual NCA’s to obtain a valid certificate for their boat.

Additional Rigs Form

Should the boat be certificated with less than the full complement of rigs then the Additional rigs Certification Control Form may be used to add additional rigs to a certificate. Once the certificate has been up dated then it need not be retained.

Check Lists

The two Check List forms are for the measurers use in conducting a certification control. They are not required to be sent to the NCA. As such, these check lists should be thought of as a work sheet of checks to be observed by the official measurer in a control only and if the boat complies with all the statements then there would be no further use for them. The check lists might be of some use to the owner of a boat which failed control as a record of what has to be corrected before a certificate is issued.

This is not part of the Certification Control Forms but is only given as a suggestion of a means of a measurer recording measurements he, or she has completed.


The term builder on the Certification Control Form is to be interpreted to mean the person who assembles the boat to sailing condition from its individual components.

The builder should then satisfy him, or herself, that the various components meet the current class rules.

Where there is any doubt as to the components compliance, the builder should ask his supplier to provide a declaration certifying the component being supplied complies with the current class rules.  This should be available to the Official Measurer at certification control.

In the case of a hull the moulder may wish to add a declaration for this purpose to his moulder’s tag.

Such a declaration should not be confused with the boat’s certificate resulting from control.
