MITENA US 10, when I knew her, was owned by John & June Van Voorhis of Rochester, New York. Too deep for the Rochester Yacht Club basin off of the Genesee River, she would have to plow her way out regularly. I was a kid, he showed me how to sail. 73 feet, a tiller, canoe stern, who could ask for more? Very fine photos of her do exist in the hands of what I understand is the first owners upon delivery, also a steamy shot of a guy at the tiller and two women relaxing on that velour seating, looking just everso.
Judge Van Voorhis left a nice R, # 57, Shadow, which it is my understanding he owned with two brothers when he bought US 10. I reckon the early 50's. I did almost no racing in those days (I was 10), but later, in the twilight of wooden racers on Lake Ontario, she was held in high regard by sailors from Rochester, Toronto, Sodus Bay, etc. I never heard anyone describe her as slow, as I have seen here.
Very understandably, something of her calibre would most likely not find a new home close to home. I had been told that she went west, out on the Lakes, but until your very kind post, I never knew where. I am most pleased to hear that she is well, 50 years later.
