The Cal Cruising 36 (often referred to as the CC36) represents a significant moment in the evolution of Jensen Marine, where the high-performance DNA of Bill Lapworth’s racing designs was purposefully adapted for long-range comfort. Introduced in the late 1960s, the Cruising 36 utilized the same proven, slippery hull form as the legendary Cal 36 racer but replaced the low-profile racing deck with a distinctive raised saloon and a more substantial interior volume. This "cruiser-on-a-racer-hull" philosophy allowed the boat to maintain a competitive edge in speed and pointing ability while offering a level of visibility and light rarely seen in sailboats of that era. Built by Jensen Marine in Costa Mesa, California, the CC36 was a precursor to the modern "deck saloon" concept, catering to sailors who wanted the pedigree of a Lapworth design without the spartan, cramped quarters of a pure 1960s offshore racer.

Sailing Performance & Handling

The sailing characteristics of the Cal Cruising 36 are defined by its racing heritage. Because it shares the underwater profile of the Cal 36—a boat known for its success in prestigious races like the Transpac—the CC36 possesses a level of agility and speed that outclasses most dedicated cruisers of its generation. According to historical design notes from Good Old Boat, the hull features a fin keel and a spade rudder, a combination that was revolutionary when Bill Lapworth first popularized it for offshore work.

While the hull is fast, the Cruising 36 carries significantly more weight than its racing sibling due to the heavier deck molding and extensive interior cabinetry. This results in a higher displacement-to-length ratio, which improves sea-kindliness and provides a more dampened motion in a seaway. On the water, the boat is known for tracking exceptionally well, though the increased windage of the raised deckhouse can be felt when maneuvering in tight quarters or during high-wind close-hauling. Sailors often report that the boat "punches above its weight" in light air, a direct benefit of the efficient Lapworth hull, while remaining stiff and predictable as the breeze freshens.

Interior Comfort & Variations

The defining feature of the Cal Cruising 36 is its interior, which was designed to provide a "live-aboard" feel that the standard Cal 36 lacked. By raising the deckhouse and incorporating large windows, Jensen Marine created a main saloon that is bathed in natural light, allowing the crew to enjoy 360-degree views from the dinette. The layout typically features a large V-berth forward, followed by a head and hanging locker. The main cabin houses a convertible dinette and a comprehensive galley that was considered quite modern for the late 1960s, often equipped with ample counter space and dedicated storage for extended voyaging.

The CC36's primary "sibling" is the original Cal 36 racer. While they share a hull, the experience on board is vastly different. The racer features a traditional low-profile coachroof and a more utilitarian, "pipe-berth" style interior, whereas the Cruising 36 focuses on rich wood finishes and ergonomic seating. There are also mentions in historical Jensen Marine literature of a "Mark II" variation in later years for other 36-foot models, but for the Cruising 36, the variations were mostly found in owner-specified engine choices, ranging from the original Perkins diesels to the ubiquitous Atomic 4 gasoline engines.

Known Issues & Buyer’s Checklist

Prospective buyers of a Cal Cruising 36 should prioritize a few specific technical areas that are common across the Jensen Marine fleet of this era.

  • Deck Core and Large Windows: The CC36 is famous for its large cabin windows. These are prone to leaking over decades if the seals have not been maintained. Persistent leaks often lead to delamination of the plywood or balsa core in the surrounding deck and cabin sides.
  • The "Cal Step": Like many Lapworth designs, the CC36 utilizes a mild steel beam (often called a "compression bridge" or "Cal beam") to support the mast load. Over time, saltwater intrusion can cause this steel to rust and expand, potentially cracking the fiberglass or compromising the structural integrity of the mast support. This is a critical inspection point.
  • Rudder Post and Bearings: The spade rudder is a high-performance feature but subjects the rudder post to significant stress. Buyers should check for excessive "slop" in the bearings and inspect the rudder blade for signs of water ingress or delamination.
  • Chainplates: The internal chainplates are glassed into the hull structure. While robust, they are difficult to inspect. Any signs of rust bleeding or staining on the interior bulkheads near the shroud attachments should be viewed with caution.

Community & Resources

Owners of the Cal Cruising 36 benefit from one of the most dedicated vintage fiberglass communities in the world. The Cal Yachts owner groups are a primary resource for technical drawings, original brochures, and DIY advice for restoring Lapworth designs. While the manufacturer is no longer in business, the sheer number of Cal boats built ensures that parts and collective knowledge remain accessible.

The Verdict

The Cal Cruising 36 is a rare "best of both worlds" vessel that successfully marries a championship-winning racing hull with a comfortable, light-filled interior. It is an ideal choice for the sailor who values performance and sailing "feel" but refuses to spend their time in a dark, cave-like cabin.

Pros:

  • Exceptional Pedigree: A Bill Lapworth hull that offers genuine sailing pleasure and speed.
  • Abundant Light: The raised saloon windows provide better visibility and interior ambiance than almost any other boat of its era.
  • Robust Construction: Built during the era of "over-built" fiberglass, these hulls are incredibly durable if properly maintained.

Cons:

  • Maintenance Intensity: Large windows and aging steel mast supports require specialized attention and potential expensive remediation.
  • Windage: The higher profile of the deckhouse makes the boat more prone to "sailing" on its anchor and adds drag when heading upwind in heavy air.
  • Age: Finding an example that has not suffered from deck leaks requires a diligent search.
