For 2018, CODA will be giving away Buffs to its members. Please see your provincial rep at the next regatta to collect yours (if you are paid up for 2018)! Being a member of the class is mandatory for racing your optimist in Canada. Throughout your racing career, you will always be required to be a member of the class of sailboat you race. This ensures you have an organization behind the scenes organizing and planning the events, rules and regulations that support fair and active racing. Being a part of a class is part of sailing.
