From the Sailboat Classes of North America, Fessenden S. Blanchard, 1963:
"In the summer of 1958 Captain Richard T. Miller, of the Ship Design Division, Bureau of Ships, U.S.N., who lives in Annapolis, Maryland, de- signed the 9'6'^ Butterball pram dinghy as a junior training boat. The most distinctive feature of the class is said to be a thick (1'%'') daggerboard with a symmetrical airfoil section. This is said to give the boat a good lift, so that she sails close to the wind and balances nicely. The designer reports that Bob Bavier (Yachting) sailed Number 1 boat in the spring of 1959 and appeared pleased with its handling qualities. Of the thirty boats so far built, most of them are located in the vicinity of Charleston, South Carolina; some are at Tacoma, Washington; others are in Texas, Michigan, Missouri, Australia, and New Zealand. Material is mahogany plywood. Captain R. T. Miller (R.F.D. 3, Box 392, Melvin Rd., Annapolis, Md. ) is the source of information on the class. The principal builder is Bill Dodds Boats (Route 1, Box 156A, Johns Island, S.C.). The price is about $400 new, one of the least expensive sailing dinghies of which we have heard.
VITAL statistics: L.O.A. 9'6"; draft without centerboard 5", with C.B. 2'$^"; sail area 49 sq. ft.; weight 150 lbs.; trailable or cartop.
