“A Classic Cat” hulls, hull appendage, rigs and sails are required to comply with the class rules here recorded.
“A Classic Cat” hulls, hull appendage, rigs and sails are measurement controlled and may be made by any manufacturer. In order to be confirm in compliance with the class rules, sails are required to be certified by an official measurer or by a manufacturer licensed under the ISAF In House Certification. These parts may be altered to the extent permitted in Section C of the class rules, after certification control has been performed.
Owners and crews should be aware that compliance with rules in Section C is NOT checked as part of the certification process.
