The Idem class dates back to 1899 - 1900 and is one of two surviving North American classes we can trace back to the Seawanhaka rating rule, (a waterline rule) that was popular before 1900. The Idem was designed by Clinton Crane as a one-design racer for the moneyed New York set that summered in the Adirondack Lakes, particularly St. Regis Lake. It is unique that the original fleet of twelve remains intact and racing (with the exception of the one that has been given to the Adirondack Museum, but the rest are serviceable). The class is to remain a "period" class (unlike the English Thames A-Raters of the same time frame) including a requirement that only cotton sails can be used. The fellow on the back deck is the mainsheet trimmer and from the photo's it doesn't look like he has a lot of mechanical advantage (i.e. multiple blocks) to ease his job with that huge mainsail. A true piece of Americana yachting history.
Bald but my eyebrows are growing at a prolific rate. Sailed Windmills and Y-Flyers in the 1960's. Founded Miami University (OH) sailing team. Sailed International 14's and Lasers in the 1970's. Sailed International Canoes in the 1980's to mid 1990's. Sailed Classic Moths since 2002. Enjoy boatbuilding though I'm very, very slow at it (the Internet doesn't help matters). Name in real life: Rod Mincher
After choosing this username (Tweezer is the name of my Classic Moth), further research on the Internet turned up that Tweezerman is a corporate name for a line of pedicure products. Let me emphasize that I do not work for, nor endorse these products.
