About the Dean 5000 Sailboat

Designed by Peter Dean and built by Dean Catamarans in South Africa between 2010 and 2014, this substantial 50-foot catamaran represents a compelling option for serious cruising sailors seeking performance and comfort. With its impressive 26-foot beam and twin-keel configuration, the Dean 5000 offers exceptional stability and generous interior volume while maintaining surprisingly shallow 4.92-foot draft access to protected anchorages. The fractional sloop rig delivers excellent sailing characteristics, with the SA/Displacement ratio of 21.11 indicating spirited performance in moderate conditions. At nearly 40,000 pounds displacement, this is a solidly built cruising platform designed for extended offshore passages rather than lightweight racing. The fiberglass construction ensures durability for long-term cruising adventures. Twin 65-horsepower engines provide reliable auxiliary power and excellent maneuverability in tight quarters or adverse conditions. The catamaran's wide beam creates exceptional living space below, making it particularly attractive for couples or families planning extended cruising. While the Dean 5000 had a relatively short production run, it represents Peter Dean's philosophy of combining seaworthy design with comfortable accommodations, making it well-suited for coastal exploration and offshore passage-making alike.
