Probably the oldest US one-design class that is still sailed. (St. Regis Lake in the Adirondacks). (2010)
Thanks to Sandy Trevor, Commodore of St. Regis YC, for providing updated photo and information on this yacht.
"Of the 12 built originally, one is in the Adirondack Museum, and the other 11 are still in sailing condition on St Regis Lake. In 2004 a 13th Idem was built, meticulously following the original Clinton Crane plans and using identical materials."
