The Gemini 105 MC is a fast, shallow draft catamaran cruiser capable of taking her people to paradise, where ever that may be. With her ability to sail very close to the wind and motor at 7 plus knots, all while sailing in comfort.

The Gemini 105 was designed to be affordable, compact, relatively easy vessels for sailors new to catamarans. Production began with the 105M (meaning 10.5 meters), with a design change in 2004 to the 105MC, notable differences being the extended cockpit cover to allow for a full enclosure and a slightly taller mast (while still remaining ICW-friendly). In fact, the “c” in the 105Mc stands for “convertible,” likening the cockpit to that of a sports car. The Gemini Owners Group has a complete list of the numerous small differences between the M and MC as well as there are owner interviews below on this website that explain differences.
