About the Cal 39 Sailboat

Designed by the legendary C. William Lapworth and built by Jensen Marine, this rare fin-keeled sloop represents a brief but notable chapter in Cal's storied history. With only 29 hulls produced during its short two-year production run from 1970-1971, the Cal 39 stands as one of the more exclusive entries in the builder's lineup. Lapworth's design philosophy shines through in the boat's balanced proportions and performance-oriented hull form. The fin keel with rudder on skeg configuration provides responsive handling while maintaining directional stability, making this boat well-suited for both spirited coastal sailing and longer passages. Her masthead sloop rig delivers respectable sailing performance with manageable sail handling for a crew of two to four. The solid fiberglass construction reflects the robust building standards of the era, contributing to the boat's reputation for durability. With a moderate comfort ratio of 25.56 and capsize screening value of 1.91, the Cal 39 strikes an appealing balance between performance and seaworthiness. These characteristics, combined with Lapworth's proven design expertise, make the Cal 39 an intriguing option for sailors seeking a capable cruiser with sporty handling characteristics and the cachet of limited production numbers.
