There were 5 of these built in 1903 for the Beverly Ma. yacht club for a racing class. None of the 5 survive. Artisan Boats in Rockport is starting the second one to deliver to Buzzards Bay this summer. I shot UNCAS last spring before launch.
Below is a nice multi media piece by Alison Langley, a marine photog. in Camden. The last few seconds are video sailing in Camden Harbor. The old boat moves pretty well.
