Manufacturer-provided information:

"First introduced on the original Gemini 105M, the hull shape of the 105Mc is still revolutionary in the multihull industry. The hulls of the Gemini 105Mc are shallow and shaped much like a "teardrop" which requires little force to move the 105Mc through the water yet it also provides a high load-carrying capacity (450 lb per hull per 1"). The bridge deck has 39" of clearance at the bow. This, combined with the lack of pitching and wave making, translates to a comfortable ride with no heeling. The shape has been tested and proven in a wide variety of conditions... surfing down 30' waves in the mid-Atlantic, sailing to Hawaii, or cruising down the Intracoastal waterway.
The Gemini hulls provide many advantages considering their weight and structural rigidity. The entire hull mold is one complete unit including the centerboard cases. This single unit eliminates any secondary bonding down the keel, at the bridge deck or around the centerboard cases making for a far stronger hull. The result - a faster, stronger, and more stable platform that provides excellent sailing performance.

"Throughout the history of the Gemini Catamaran, the centerboards have always been her secret weapon and the reason why she points so well to windward. The lift-able boards provide plenty of 'grip' while going to windward yet are easily retractable.
Sailing downwind, the boards are raised thus minimizing drag and maximizing performance. The 105Mc's centerboards combine the pivoting, kick up cruising convenience of centerboards, with the remarkably efficient shape of dagger boards.
The centerboards in the Gemini 105Mc have an advanced asymmetric shape that lifts the boat to windward with reduced drag. The boards are now molded with closed cell foam, which ensures they will last a lifetime.
The centerboard's case has a Plexiglas cover enabling the operator to see whether they are up or down. Centerboards are operated from inside and will easily kick up if the boat is grounded The boards extend 5' 6" in the down position and 18" when up.

"The 105Mc gets up to speed quickly with her Selden minimal fractional rig with a single adjustable back stays on a 1 ft. crane. This new, efficient full battened, big head mainsail goes behind the backstay improving drive and reducing heel. The advanced design of this Dave Beirig designed sail allows it to easily pass through the backstay. The optional 200% "screacher" sail (included on this boat) is mounted on a curved track to enable you to pull it to windward for maximum efficiency. This unique system is a cruisers' dream; a spinnaker substitute that can be rolled in and out, as well as a racers option for its ability to be used for upwind work in light airs.

"The First-Ever Lifting, Underhung Rudder System in a Cruising Catamaran. The rudders are mechanically joined through the steering system and will steer the boat at 3' or 18" of water without putting any extra load on the helm. In fact, the Gemini exhibits little to no weather helm. Her steering is precise, balanced, and easy. Using two sets of lines, the rudders can be raised or lowered - and automatically raise if and when the boat enters shallow water. A solid 1 ½" stainless steel post that runs through the middle of each rudder making it exceptionally strong. The rudders are very well balanced and easily kick up if they hit the bottom."

Upon boarding the Gemini one notices a stable on-the-water platform and a large enclosed cockpit with a large companionway door leading directly into the open and airy saloon. A useful feature is the opening window on the companionway door allowing excellent ventilation and communication to those inside.

Starting forward a queen-sized berth is located in the owners cabin just starboard of the center-line forward. This is a private cabin with excellent cabinetry and storage. The galley is located aft of the owners' cabin and includes a two burner propane stove and oven, a deep stainless steel sink, pressurized faucet, a manual fresh water foot pump, and extensive storage in three storage lockers. There is generous counter prep space forward of the sink and opposite the sink. Continuing aft is a twin cabin for guests. Up one step to the salon the u-shaped settee provides great entertaining and seating space for 6 to 8 people.

Down one step to port you will find the head located forward featuring a head/shower area with a folding plexiglass door separating the shower area from the head. Heading aft on the port side you will find the chart area and storage. All the way aft is another twin guest cabin for guests.

Large polycarbonate windows provide excellent viewing and ample light giving the interior an open and airy feeling.

STRATIPONT® Teak & Holly cabin soles and teak trim create a clean and inviting environment.

Cabin heat is supplied by a Webasto forced air heater. The owner says it provide comfortable heat on the low setting.

Broker's Comments

This capable Gemini 105MC features a large owners' cabin, two additional staterooms, and a convertible dinette. Known for having plenty of room for friends and family, she sleeps up to eight. The 105MC works as a live-aboard or long range cruiser.The catamaran design provides a very open and airy feel. This 34’ feels much larger while requiring only a standard slip at most marinas -- remember -- only a 14' beam.

The multiple overhead hatches, port lights and saloon window provide abundant light and ventilation.

Interior fabrics are ready to be replaced however this Gemini is ready to go cruising with her new owners
