2007 Gemini 105Mc

San Deigo, California


The Gemini 105Mc is probably America's most popular cruising catamaran.  This original owner boat has seen light use and excellent care.

The Gemini is a very enjoyable boat to sail, with the centerboards down she has good performance to windward and with them raised you are able to get into secluded anchorages inaccessible to other yachts.  With only 14' beam the Gemini is also able to fit into a marina slip, eliminating the need for an end-tie berth.

    The mast features a minimal fractional rig with a single adjustable back stay on a 1 ft. crane. The full battened, big head mainsail goes behind the backstay improving drive and reducing heel. There is a curved traveller track between the bows and forward of the headstay to be used with the 200% screecher. The track allows the headsail to be pulled to windward when sailing off the wind for better sail shape and performance. The mainsail has been up four times, the Genoa out twice and the screecher has never been used
