S/V Exhale is a Great Oak Landing, MD based 2004 Gemini 105 Catamaran For Sale By Owner
This catamaran owner requires financial settlement only. Trades will not be considered.

S/V Exhale is a 2004 Gemini 105Mc located in Safe Harbor Great Oak Landings, MD.  The Gemini 105Mc is a new and improved version of the original 105 M with an extended cockpit cover to allow for a full enclosure and a slightly taller mast (while still remaining ICW-friendly).  The “C” in the 105MC stands for “convertible,” likening the cockpit to that of a sports car.

We have owned this Gemini 105Mc for 5 years in the upper Chesapeake Bay and used during summer months on weekends only.  She has been hauled out for each winter.  The winter cover is included.

The Sonic drive was replaced before we purchased her 5 years ago.  We replaced the transom plate with a new double lock – no more problems backing up.  We have a spare Y part as well.  We installed auto bilge pumps, replaced two hatches, put on a new Mantus anchor and 50 feet chain.  The engine has a little over 900 hours and runs great.

The sails are original, but in good shape, cleaned and repaired last year.  Winter and summer enclosures are included and need some repairs. The bow tent and stern sunshades are also included.
