I am enquiring for a friend who is the owner of a 20ft Spaulding Clipper sloop. As far as he can tell his is the only one left in existence. Does anyone know of any others? He purchased and restored the boat in the early 80s and has never seen another one. The boat was designed and built by Myron Spaulding in Sausalito, CA in the 1940s. Record show that there were 63 of them built.
