Tom Ehman’s San Francisco Yacht Racing Challenge is a great idea. The proposed boats are NOT 12 meters. The International rule is like a sonnet; it sets particular parameters that allow latitude. These boats as I see them and as described do not fit the rule.
These boats will be more lively and quicker on their feet, but they are not 12 meters.
There is no reason the 2 meter class could not do a regatta on the same format using 12 meters, not, not 12 meters.
