Design and Construction
Lapworth drew the Cal 36 as a fiberglass monohull with a 27-foot waterline, 10-foot-4-inch beam, and 11,200-pound displacement carried on a 5-foot-7-inch maximum draft fin keel. Those numbers place her firmly in the performance-oriented camp: a relatively light, beamy hull with a long-ish waterline for her length that blends racing capabilities with cruising comfort rather than sacrificing one to the other. Jensen Marine built the standard boat in the United States, and the same yard — under Bangor Punta Corp. after the 1965 acquisition — also produced the Cal Cruising 36, a shallow-draft variant offered between 1968 and 1970 for sailors who needed less appendage below. The standard design's production ran from 1966 onward, sitting inside a marque that itself ceased building boats in 1989.
Rig and Sail Plan
The masthead sloop rig is sized to the hull with an I dimension of 42 feet, J of 14 feet 6 inches, P of 36 feet 6 inches, and E of 16 feet 3 inches, giving a foretriangle and mainsail plan consistent with Lapworth's racing-derived proportions. The 600 square feet of sail area quoted in the class data, set on that tall rig, explains much of the lively performance character noted by period observers. A boat of this rig and displacement answers to trim quickly, and the Lapworth pedigree shows in a hull that was explicitly known for its performance-oriented design from the first season afloat.
Accommodations and Intended Use
Where many racer-cruisers of the mid-1960s leaned hard toward the race course, the Cal 36 was pitched as a dual-purpose vessel and has earned a reputation as a popular choice for coastal and moderate blue water sailing. The 80-gallon water capacity and 30-gallon gasoline tankage supported weekends and longer hops without claiming true long-range cruiser provisioning, and the 30-horsepower Universal Atomic 4 gasoline engine gave a single-engine auxiliary appropriate to the displacement. The cabin plan, within the 35-foot-6-inch LOA, was laid out to let a couple or small family cruise without the stripped interior of a pure racer.
The Verdict
The Cal 36 is a Lapworth-designed fiberglass sloop that has aged into a credible used-classic: quick under sail, competent on moderate offshore routes, and still well represented in both club racing and cruising fleets. The shallow-draft Cal Cruising 36 gives buyers a draft-reduced alternative from the 1968–1970 window. She is not a heavy-displacement passagemaker, and the gasoline Atomic 4 places her firmly in the gasoline-auxiliary camp of her era.
Pros
- Performance-oriented Lapworth hull that blends racing and cruising
- Active one-design and cruising fleet decades after production ended
- Shallow-draft variant available for shoal-water sailors
Cons
- Gasoline Atomic 4 auxiliary rather than modern diesel
- Moderate tankage limits true long-range independence
