The Stone Horse is a 23' long cutter rig sloop, originally built in wood, and later versions in fiberglass. The designer was S. S. Crocker, a very well-known and well-respected American yacht designer, who published the design in 1931. It was available as sloop-rigged or as a ketch.

A boat yard a mile away from the beach I summered at as a child built the boats. They were distinctive in that they had a black hull and a terra-cotta sail, in a time when all the other boats featured white sails. I fell in love with the colors and the lines of this boat, and it was my first recollection of having an actual design thought.
