Midships--galley with stove, oven, broiler, refrigeration;
Forward--access to forward master stateroom;
Port hull--6'4" headroom, double berth cabin aft, long storage area midships, head with marine toilet forward;

Like her small sistership, the 3200, the Gemini 3400 combines a high degree of sailing performance with comfortable cruising on a family-oriented boat.
Her hulls differs slightly from the 3200 by incorporating low aspect ratio fixed keels, molded steps in the reverse-style transoms and the use of inboard rudders.
Standing headroom throughout the interior, three double staterooms and added touches such as twin inboard diesel engines, a rigid pilothouse and a spacious saloon cabin make this an easy boat to live aboard. The Gemini 3400 represents a logical upgrade from the 3200 and is a good choice for comfortable cruising.

Gemini catamarans have been in production since 1981, starting off with the prototype model 31, and evolving through the 3000 to the present 3200 and recently introduced 3400 models.
As you can see Gemini is not a "new cat on the scene", she has been evolving over the past decade and a half until we have a cruising catamaran which offers a wonderful responsive and fun sailing boat, easily handled and roomy for comfortable cruising for a couple or single sailor or a family.
The first 3200 was launched in March 1990, and we have been building and delivering an average of one boat a week since then. Obviously there is an active owners' association, with its own newsletter, and rendezvous are being organized around the country, in such places as New England, Chesapeake Bay, Florida, Catalina Island and Puget Sound.
Gemini has all the usual features of a well designed cruising catamaran, plus a good deal more. A well designed catamaran should give you an easily sailed boat, allowing you to arrive at your destination without feeling like you have just had a workout. It should give you lots of room inside, with plenty of storage and headroom and good ventilation.
Gemini's hulls are easily driven, without the small keels offered by the other catamarans. Centerboards have two main advantages, when they are retracted they provide Gemini with a completely clean underbody, with no drag through the water. With the boards down they provide 5'6" of lateral resistance, enabling the boat to tack through 70 degree wind. The boards are easy to operate and unnoticeable inside the boat, without interfering with the accommodation. Obviously 18 inches of uncluttered draft makes a boat that will go anywhere, into the most interesting of places that always have "thin" water.
The accommodation on Gemini is unsurpassed, even on a 40 foot monohull, however much you pay for it! With a large cockpit to easily seat eight people and a dinette area on the bridge deck with comfortable seats for six to eight, with a teak table that unfolds from a fiddled "card table" into a full size dining table, all within easy reach of a refrigerator which runs on propane or 110v.
The starboard hull houses the galley, with an ungimballed propane stove, with two burners and an oven, double stainless steel sink, and a silverware drawer, with lots of storage and work surfaces. From the dinette into the port hull is the navigation area with room for chart storage and all the tools and instruments you would ever need. Forward of this hull is the molded head, with a marine toilet, with an 18 gallon holding tank, propane water heater, which supplies hot water to the head and the galley, washbasin and medicine cabinet and surfaces, and a hand held shower with a sump pump. . . all this is fitted into a fiberglass liner, making it very practical to clean and dry after use.
Sleeping accommodation is superb, with a master cabin in the forward port hull, with a queen size bed, teak vanity unit and bookcase, and a hanging closet, a true waterfront bedroom! There are also two double cabins with hanging lockers and vanities in the aft of each hull.
Under each of the aft bunks are two 30 gallon water tanks, giving a total of sixty gallons of fresh water, and pressure water is a standard feature.
With the introduction of the Gemini 3400 in 1993 we can now offer molded transom steps, giving easy access from the water, and adding a new dimension to the profile of Gemini. The 3400 centerboard offers a suitable outboard of your choice
The 3400 is the best value for a blue water cruiser, possibly in the world. She is simple, strong, functional and innovative, with the biggest and most loyal following in the fast growing multihull world.
Geminis have safely and comfortably sailed many sea miles on many oceans, lakes, rivers and canals, and will continue to do so for many more years, giving a lot of pleasure to many hundreds of happy owners.
Gemini 3400 Construction
Gemini has a simple two part construction, molded hull and molded deck, with a large single interior mold over the bridgedeck giving the dinette seats, steps to each hull, the mold coming back from the forward bulkhead to the aft lockers in the aft cabins. This molding is glassed into the bridgedeck prior to lifting, giving strength by a double skin on the bridgedeck. The hull and deck are mechanically and chemically bonded, overlapping the deck over the hull, bonding with a polyester putty and pulling the seal together with bolts and backing nuts every four inches, then a double gunwhale guard over the bond. The hull is a laminate of woven roving and matt, with polyester resin, over an initial layer of gel coat with vinylester resin and a veil fiberglass fabric for blister protection. The deck has half-inch end grain balsa sandwich on the foredeck, around the cockpit and across the cabin top. No deck fittings are drilled through this sandwich, therefore the integrity of the seal is not destroyed.
The center boards are light, strong mahogany plywood, two inches thick, a very simple rope and drum mechanism has resulted in a negligible number of problems of any kind with the centerboards. The case is molded as part of each hull, with no joins or seals, therefore it is virtually impossible to split or break the centerboard case. The mechanism of the pivoting centerboard allows the board to kick up if run aground, and the construction allows for extremely easy use, positive buoyancy means that the board is locked down, and floats up, unlike regular centerboards on monohulls that are usually weighted and need cranking up into the hull.
The 3400 has two underhung spade rudders, which are also adjustable to the eighteen inches draft of the boat, whilst still being steerable. These rudders will also kick up if necessary.
