Mast Sleeves Must Respect 3mm Rule
Hey Optimistas, the IODA Technical Committee put out a notice regarding Mast Collars and Sleeves, it seems that manufacturers have been producing mast collar and sleeves with loose tolerances, which is in violation of Class Rule 3.2.5 (f).
We recommend checking your Mast sleeve and collar on your boat if possible, as perhaps general wear and tear has made the tolerances loose on your boat. Be ready for the IODA Championships when they return! Full document reproduced below:
