About the Dee 25 Sailboat

Designed by Peter Brett in the early 1950s, this classic wooden cutter represents the golden age of British yacht design when seaworthiness took precedence over speed. Built by Alanson & Son in the UK, only 25 of these distinctive vessels were constructed, making them a rare sight on today's waters. The Dee 25's traditional long keel configuration and substantial displacement of 11,000 pounds create exceptional stability and tracking ability, while the generous ballast ratio ensures excellent self-righting characteristics. Her cutter rig provides versatile sail handling options, particularly valuable when coastal cruising or making longer passages where changing conditions demand flexibility. With a comfort ratio of 32.82, this yacht prioritizes motion comfort over performance, making her well-suited for serious cruising sailors who value a steady, predictable platform. The robust wooden construction reflects the craftsmanship standards of her era, though prospective owners should carefully evaluate the condition of hull, deck, and structural components given the age of these vessels. Her hull speed of 6.70 knots and capsize screening value of 1.67 indicate conservative but safe passage-making capabilities, making the Dee 25 an appealing choice for traditional sailing enthusiasts seeking a characterful vessel with proven offshore credentials.
