According to this rule:
G.2.2 CERTIFICATION (a) Except where sails are certified as in (b) the official measurer shall certify sails in the tack and shall date each with the date of certification control. (b) An MNA may appoint one or more persons at a sailmaker to certify sails produced by that manufacturer. A special licence shall be awarded for that purpose.
AND ON THE RIG MEASUREMENT FORM:
MAINSAILS
31. G.2.2(b) If the sails have been certificated by a manufacturer awarded a special license, then omit steps 32 to 60
HEADSAILS
60. G.2.2 (b) If the sails have been certificated by a manufacturer awarded a special licence, omit steps 62 to 86
Where can we get the list of manufacturers who have been awarded this special licence, and what sail markings are required to indicate that they have been 'pre-certified' ?

Re: Certified sailmakers
Hi Art,
Thanks again for your question.
The short answer is that there are no licensed IOM class sailmakers in the terms of Class Rule G.2.2(b).
G.2.2(b) was adopted into the IOM Class Rules from the World Sailing Standard Class Rules (SCR) and refers to the World Sailing In-House Equipment Certification (IHC) programme – see https://www.sailing.org/inside-world-sa ... ification/. At present, the International One Metre class is not a participating class association and, given the way in which the IHC programme operates, it is difficult to see how it would be feasible. As a result, there are no certified IOM sailmakers.
The VC Measurement is reviewing this process with a view to making it more relevant for IOM sailmakers and owners.
Regards
Andrew
