About the Csy 33 Sailboat

Designed by Peter Schmitt and built by CSY from 1978 to 1981, this 33-footer represents a classic approach to blue water cruising during the height of the fiberglass production boat era. With only 59 hulls produced during its brief four-year production run, the CSY 33 has earned a reputation as a solid, seaworthy cruiser among those familiar with the marque. The design emphasizes offshore capability over racing performance, evident in its substantial 15,300-pound displacement and conservative comfort ratio of 35.38. The fin keel with rudder mounted on a protective skeg provides good directional stability while offering reasonable protection for the steering system during groundings. Her cutter rig configuration enhances versatility in varying wind conditions, making sail handling more manageable during extended passages. Built with traditional fiberglass construction methods of the late 1970s, these boats typically feature robust layup schedules that prioritize durability over weight savings. The beam of 11 feet provides adequate interior volume while maintaining seaworthily proportions, and the moderate sail area to displacement ratio of 14.04 suggests predictable handling characteristics rather than spirited performance. For sailors seeking a capable coastal and offshore cruiser with proven seakeeping abilities, the CSY 33 offers the substantial feel and reassuring motion that characterized quality production cruisers of its generation.
