About the Cal 25 Sailboat

Originally designed by Bill Lapworth and built by Jensen Marine, this compact coastal cruiser emerged during the height of California's fiberglass boat building boom in the 1960s. The Cal 25 represents the philosophy of its era: affordable performance sailing for weekend warriors and aspiring sailors looking to step up from dinghies. With its moderate displacement hull and traditional fin keel configuration, the design strikes a practical balance between sailing performance and interior comfort. The boat exhibits the characteristic Cal styling of its period, featuring clean lines and functional deck layout that made the brand popular among West Coast sailors. Best suited for coastal cruising and day sailing, the Cal 25 offers enough cabin space for overnight trips while remaining manageable for single-handed or small crew sailing. The cockpit provides comfortable seating for several adults, making it an excellent choice for sailing instruction or casual entertaining on the water. While not built for extended offshore passages, the Cal 25 has proven itself as a reliable coastal companion. Its size makes it trailerable with proper equipment, adding versatility for sailors who want to explore different cruising grounds. The design remains popular in the used boat market as an affordable entry point into comfortable keelboat sailing.
