Gemini 105M Buyer's Guide
The Gemini 105M is a 33-foot 6-inch Tony Smith-designed catamaran built in the United States, with a narrow-beam hull whose 14-foot width and retractable centerboards make it unusual among cats for slipping into standard slips, and whose solid-molded hull construction rewards a buyer who inspects the right details rather than the usual multihull worry list.
Layouts on the Used Market
Owner three-cabin arrangements are the more common find among used Gemini 105Ms, though both owner and ex-charter versions appear with regularity. The standard plan puts a centerline master stateroom forward, a port hull with head, nav station and aft double, and a starboard hull with amidships galley and aft double, sleeping six at need. Ex-charter boats will often show higher hours and more systems wear but bring the same 14-foot-beam, 18-inch-boards-up draft hull that made the design attractive to fleets.
Equipment and Common Upgrades
Well-equipped used 105Ms commonly carry dinghy davits, solar, a chartplotter, air conditioning, a freezer, bimini, swim platform and autopilot as factory or early additions. For a buyer, the power-and-energy cluster—solar with a freezer and sometimes an inverter—determines whether the boat can sit at anchor without a generator, while the canvas-and-handling cluster of davits and bimini shapes dinghy life and cockpit shade. Navigation is usually settled by chartplotter and autopilot. Less common owner upgrades include heating, wind generator, hot water, washing machine, trampoline, radar, AIS, EPIRB and life raft; these appear on individual boats and are worth confirming rather than assuming.
What to Inspect
The helmsman cannot reach the mainsheet or genoa sheet winches from the wheel, so check that the trunkhouse winch positions and traveler leads are intact and that no ad-hoc steering-station modifications were attempted. The hull is solid hand-laid fiberglass with a barrier coat and vinylester resin for blister protection, and the deck is balsa-cored on horizontal surfaces—inspect deck cores for softness around fittings. Centerboards are epoxy-treated mahogany and must be locked in place owing to buoyancy; verify they retract freely and the locking gear holds. The hull-deck flange is through-bolted on 4-inch centers under a PVC rubbing strake, so lift the strake and check for corrosion or seam separation.
Availability and Buyer's Takeaway
Typical markets for the Gemini 105M are the United States and the United Kingdom. For the shopper, the short list is: confirm the three-cabin layout fits your plans, verify solar-freezer-autopilot function for off-grid use, cycle the centerboards and check the flange bolts, and accept the winch-reach limitation as a crew-positioning fact rather than a defect. A solid, narrow cruising cat with real liveaboard bones.
