About the Cal 35 Cruise Sailboat

Designed by the renowned C. William Lapworth and built by Cal-Boats from 1973-1974, this classic 35-footer represents a brief but notable chapter in Cal's storied history. With only 120 hulls produced during its short two-year run, the Cal 35 Cruise has become a sought-after example of early 1970s fiberglass construction and thoughtful design proportions. The boat's fin keel and spade rudder configuration, combined with a moderate displacement of 15,000 pounds and 5,000 pounds of ballast, creates a well-balanced platform suitable for both coastal cruising and occasional offshore passages. Her masthead sloop rig carries 546 square feet of sail area, providing adequate power while remaining manageable for a small crew. The 11-foot beam offers comfortable interior volume without sacrificing sailing performance. Lapworth's design expertise shines through in the boat's sailing characteristics, delivering the reliable performance Cal became known for during this era. The comfortable cockpit and practical deck layout make her equally suited for weekend coastal adventures or extended cruising. While not built for racing, the Cal 35 Cruise offers that classic blend of seaworthiness and livability that defines quality cruising sailboats from this period.
