Used Cal 24 Sailboats for Sale

The Cal 24 holds a singular position in American yachting history as the vessel that launched Jensen Marine and established the legendary partnership between Jack Jensen and naval architect C. William Lapworth. Originally introduced in 1958 as the Lapworth 24, the design was a radical departure from the heavy, full-keeled wooden cruisers of the era. Built from the then-revolutionary medium of fiberglass, it was a light-displacement, centerboard-equipped racer-cruiser that could be easily trailered—a concept that helped democratize coastal sailing. While the "Cal" name would later be synonymous with ocean-crossing icons like the Cal 40, the 24-foot platform served as the engineering laboratory for Lapworth's theories on hull speed and surfability. Over its production life, the model evolved through several distinct iterations: the original centerboard "Lapworth 24," the fixed-keel Cal 24 Mark II, the flush-decked Cal T/4 designed for the IOR "Quarter Ton" rule, and finally the Cal 24-3 designed by C. Raymond Hunt Associates in the 1980s.
