Gemini 105 MC Buyer's Guide
The Gemini 105 MC on the used market is the 33.5-foot owner-cruiser catamaran Tony Smith developed through three generations of his 34-foot class for Performance Cruising Inc., with more than 1,000 Gemini catamarans built over three decades. She is a modestly sized multihull aimed at the private owner rather than the charter template, though ex-charter examples are common. A shopper will find a boat with solid-glass hulls and a light, open cabin that rewards careful inspection of its bonded structure and buried systems.
Layouts on the Used Market
Owner three-cabin arrangements are the more common on the brokerage market, but both owner and ex-charter layouts appear. The standard plan places a queen island berth forward amidships to starboard, a head forward to port, an elongated galley to starboard, and a navigator’s station to port, with twin aft double staterooms. The saloon spans the 14-foot beam with a C-shaped dining table that converts to a double berth, and the cockpit adds living space. Ex-charter boats may show harder use of the same volumes but carry the same structural bones.
Equipment and Common Upgrades
Power and energy systems are commonly fitted with solar, an inverter, lithium batteries, and a watermaker, and air conditioning is common in warmer markets. A chartplotter and autopilot are commonly fitted, with dinghy davits usual for tender handling. Often-seen additions include a bimini, radar, and Starlink connectivity. For sail handling, an asymmetric spinnaker is a less common owner upgrade, while the factory screecher option of 490 square feet remains a notable light-air asset where fitted. A hardtop and cockpit shower appear only as occasional upgrades.
What to Inspect
The hull-deck joint is a shoebox bonded with a polyurethane putty and fastened on 5-inch centers under a gunwale guard, so check for any separation or guard leak paths. Liners are glassed and tabbed before deck installation, and the wiring looms are virtually inaccessible behind them, meaning a survey should probe for prior unrecorded cuts. The asymmetric centerboards pivot on fiberglass-and-Kevlar foam and raise from the saloon, so verify cavity condition and lift-line wear. Spare hoses and PVC-run 12-volt wires were built in, but mast wires enter the forward stateroom panel and deserve a continuity test.
Availability and Buyer's Takeaway
These catamarans turn up across the United States, the U.S. and British Virgin Islands, the Dominican Republic, Mexico, and Canada. A buyer should:
- Confirm centerboard cavities and saloon lift lines are sound
- Inspect hull-deck joint and gunwale guard for bond failure
- Test all wiring at the forward-stateroom mast panel
- Verify generator and propane locker closures in the cockpit
- Prefer owner layouts unless charter wear is acceptable
