Designed by the renowned C. William Lapworth and built by Jensen Marine from 1967 to 1972, this substantial cruising yacht represents the California builder's foray into serious offshore sailing. With only 18 hulls produced during its five-year production run, the Cal Cruising 46 remains a relatively rare find among vintage fiberglass sailboats. The yacht's impressive 30,000-pound displacement and moderate comfort ratio of 40.21 make it well-suited for extended offshore passages and coastal cruising. Lapworth's design features a fin keel with spade rudder configuration that provides good maneuverability while maintaining directional stability. The masthead sloop rig with 827 square feet of sail area delivers respectable performance, with the SA/Displacement ratio of 13.76 indicating a boat that moves well in moderate conditions without being overpowered. Built during Cal's golden era, this model embodies the transition from racing-oriented designs to more comfort-focused cruising boats. The robust construction and generous proportions, including a 12.50-foot beam, provide ample interior volume for extended living aboard. With its favorable capsize screening value of 1.61, the Cal Cruising 46 demonstrates the seaworthiness expected from serious offshore cruising vessels of this vintage.
