MFG built many boats, including at least 16 sailboats: Sidewinder 16, Pheonix 18, Copperhead 14, Bandit 15 and 17, MFG 19, Cobra 23, Pintail 14, Whistler 11, Shark 20 catamaran, Ford 20, Whip 17, Challenger 10, Dingo 15, Redhead 17 and the Teal 16, pictured below.

The history of MFG (Molded Fiber Glass) is fascinating and closely parallels the development and improvement of molded fiberglass. The company, founded in Ohio by Robert S. Morrison. was the original contractor for the fiberglass body of General Motor's Chevrolet Corvette. Morrison had no interest in boats, but in the early 60s, fiberglass boats were becoming very popular and only a few people were buying Corvettes. The Anchor Boat division of MFG was founded in Union City, PA to produce small motorboats, many of which were sold by the Sears & Roebuck Company. According to Sailboat Data, the origins of the sail boat division are cloudy. Some of the first sailboats were built by Anchor Reinforced Plastics of Hazel Park, MI.   MFG also bought the Lasalle, Michigan-based Gibbs Boat company. For a time, MFG sailboats were sold under the name 'SailMFG.' There is still an MFG plant located in Conneauteville, PA, but I am not sure that it is still in operation or producing boats.

Carlton Ellis of DuPont was awarded a patent for polyester resin in 1936. The Germans furthered the manufacturing process of this early polyester by refining its curing process. Early in World War II, British Intelligence stole these secrets and turned them over to American firms. American Cyanamid produced the direct forerunner of today's polyester resin in 1942. This early polyester resin quickly ended up in a number of manufacturing hands. Owens-Corning had been experimenting with fiberglass cloth and resin combinations to create structural elements for airplanes. By 1942, the company was turning out fiberglass and polyester airplane parts for the war effort. Back in Toledo, Ray Greene, who had studied plastics while a student at Ohio State, had been working with Owens-Corning on fiberglass composites. He had made composite boats as early as 1937, but was searching for just the right plastic to use for boats. He received a shipment of the polyester resin in 1942 and produced a daysailer.
