The Cape Cod Gemini is an American sailing dinghy that was designed by A. Sidney DeWolf Herreshoff as a day sailer and first built in 1955.
[1][2][3][4][5] The design was initially built by the Herreshoff Manufacturing Company and later by Cape Cod Shipbuilding in the United States.
It has a fractional sloop rig, a plumb stem, an angled transom, a transom-hung rudder controlled by a tiller and twin retractable leeboards.
[1][4] The boat has a draft of 3.33 ft (1.01 m) with a leeboard extended and 7 in (18 cm) with both retracted, allowing operation in shallow water, beaching or ground transportation on a trailer.
[1][4] The design is normally sailed with a crew of two sailors, but can accommodate up to five adults.
