Swan 50-S&S Sailboats for Sale & Market Overview

The Swan 50-S&S represents one of the rarest and most enigmatic chapters in the storied history of Nautor’s Swan. Designed by the legendary firm Sparkman & Stephens (S&S Design #2035) and launched between 1970 and 1971, only two hulls were ever produced: Casades and Kez. This model serves as a vital evolutionary bridge between the earlier, smaller S&S designs and the iconic Swan 55 and 65 models that would eventually define the "Golden Era" of Finnish boatbuilding. According to the Classic Swan Association, the 50-S&S was conceived during a period of rapid experimentation in hull forms, reflecting the transition from traditional long-keeled shapes to the more modern, separate skeg-and-rudder configurations that improved maneuverability without sacrificing the legendary S&S tracking. While it lacks the high production numbers of its siblings, the Swan 50-S&S is revered by maritime historians as a "pure" expression of Olin Stephens’ philosophy—combining a powerful sail plan with a hull capable of weathering the most punishing offshore conditions.
