Comment:
"GEMINI
The 16' 1" sloop Gemini, designed by Sidney De W. Herreshoff, came on the market early in 1962 when it was shown at the New York Motor Boat Show. Built by the Cape Cod Shipbuilding Company (Wareham, Mass.), with a modern round-bottom planing hull and rig, its unusual feature is twin boards instead of one centerboard. While this has been a feature of the Inland Lake Scows, it is seldom seen on other single-hulled craft. The builder calls attention to the following points:
In our testing, the boat with two boards was much faster than the same model with one centerboard. The experts will surely agree that a board kept perpendicular, when heeling, offers more efficient lateral resistance, consequently, a much smaller board is used with less wetted surface, resulting in a faster boat. Thus our reasoning for installing the boards at the angle of average heel rather than vertical. The Gem does have a board for each tack where it is most efficient. She sails best with leeboard down and weatherboard up. However, she will sail well with both boards down and, of course, downwind with both up. She is easy to sail. Neither skipper nor crew need any particular training to handle her twin boards.
The centerboard box is completely enclosed. There is an outboard-motor well molded as an integral part of the deck and draining through the transom. This looks like a most interesting boat and should go fast. Construction is of fiber glass. Price is $1500.
Vital statistics: L.O.A. 16' 1"; waterline 14' 9"; beam 5' 7"; draft without centerboard 7", with C.B. 3' 4"; sail area 140 sq. ft. (spinnaker allowed); weight 440 lbs.; trailable." (Source: Blanchard, Fessenden S. The Sailboat Classes of North America." Garden City, New York, 1963, p. 95.)
"The Gemini was still being built by Cape Cod Boatbuilding in Wareham, Mass. in 2009. It had two retractable bilge boards." (Source: van der Linde, Claas. 2008.)
