S&S design #1497. (At this time, William Shaw was an employee with S&S.)
Reportedly, O'Day Corp. farmed out the construction of this yacht to a number of different firms. The first was Lunn Laminates on LI, NY. ,(predecessor to Allied Yachts).,
Marscot Plastics was an O'Day subsidiary located at Fall River, MA.
A few may have been finished by J.J. Taylor of Canada.
An unknown number of boats were built with a wood deck and coachroof as a result of a fire which destroyed the deck molds.
Another version was later built by Yankee Yachts in California. See DOLPHIN 24 (YANKEE). The Palmer Husky gas inboard was available as an option.
