Designed by the renowned French naval architecture firm Van Peteghem/Lauriot-Prevost, this catamaran represents an early entry in Lagoon's successful lineup of cruising multihulls. Built between 1990 and 1994 with only 51 units produced, the Lagoon 42 has become a sought-after vessel among cruising enthusiasts who appreciate its blend of performance and comfort. The twin-keel catamaran configuration provides exceptional stability and shallow draft capabilities, making it ideal for coastal cruising and gunkholing in areas where monohulls fear to tread. With its fractional sloop rig and generous sail area, the boat delivers respectable sailing performance while maintaining the spacious accommodations that catamarans are famous for. The wide 22.67-foot beam creates expansive living spaces both above and below deck, perfect for extended cruising or liveaboard situations. Construction quality reflects Jeanneau's reputation for building solid cruising boats, with fiberglass hull and deck providing durability for offshore passages. The relatively light displacement combined with the catamaran's inherent stability makes this vessel well-suited for couples or small families seeking comfortable coastal cruising with occasional offshore capabilities. Its limited production run has helped maintain strong resale values in today's market.
