About the Rob Roy 23 Sailboat

Designed by renowned naval architect Ted Brewer, this compact fractional yawl represents a thoughtful approach to small-boat cruising with offshore capability. Built by Marine Concepts from 1980 to 2001, the Rob Roy 23 attracted sailors seeking a seaworthy pocket cruiser that could handle both coastal adventures and extended passages. The design's most distinctive feature is its keel/centerboard configuration, which combines the tracking stability of a fixed keel with the shallow-water versatility of a retractable centerboard. This dual system allows access to thin-water anchorages while maintaining excellent windward performance. The fractional yawl rig provides balanced sail handling and versatility, with the mizzen offering additional options for heavy weather sailing and harbor maneuvering. With moderate displacement and a comfort ratio of 11.14, this boat strikes a practical balance between performance and seaworthiness. The relatively high ballast-to-displacement ratio contributes to good stability, while the hull's traditional lines reflect Brewer's emphasis on seakindly motion offshore. Despite measuring just over 28 feet overall, the design has earned respect among small-boat voyagers for its robust construction and well-proportioned accommodations. Limited to 85 hulls during its production run, the Rob Roy 23 remains a sought-after choice for sailors prioritizing quality over quantity in the pocket cruiser market.
