Koopmans 33 Sailboats for Sale

The Koopmans 33 represents the quintessential Dutch approach to bluewater cruising: a design philosophy that prioritizes structural integrity, directional stability, and safety in heavy weather. Designed by the legendary Dick Koopmans Sr., this 33foot vessel (often measuring closer to 10 meters in overall length depending on the specific build) was conceived during an era when the designer’s "Sframe" hulls and moderate displacement were the gold standards for North Sea passagemaking. Unlike massproduced coastal cruisers of the same length, the Koopmans 33 was frequently built as a semicustom project in aluminum or steel, most notably by the renowned Dutch yard Aluboot, though glassreinforced plastic (GRP) versions also exist under the related Victoire 933 lineage. As noted by Dick Koopmans Jachtontwerper, the design focuses on a balance of frictional resistance and wavemaking resistance to ensure a predictable, comfortable motion at sea.
