Gemini 3400 Sailboats for Sale & Market Overview

The Gemini 3400, produced by Performance Cruising between 1990 and 1992, represents a critical evolutionary step in Tony Smith’s quest to create the ultimate "American-sized" cruising catamaran. Following the success of the Gemini 3000 and 3200, the 3400 was the final iteration of the original hull shape before the introduction of the wider, more modern 105 series. The boat’s defining characteristic—and the source of its enduring popularity—is its 14-foot beam. This specific width allows the Gemini 3400 to fit into standard marina slips designed for monohulls, effectively removing one of the primary logistical barriers to catamaran ownership. Built in Annapolis, Maryland, the 3400 utilized a solid fiberglass hull below the waterline with balsa coring in the topsides and deck for weight reduction. It remains a staple of the coastal cruising community, offering a blend of shallow-draft versatility and remarkable interior volume for its length.
