The Cal 2-27, introduced in 1974, represents a refined evolution in the celebrated partnership between designer C. William Lapworth and Jensen Marine. While the original Cal 27 (often called the "Pop-top" or "Flush-deck" version) earned its reputation as a formidable Midget Ocean Racing Club (MORC) contender, the Cal 2-27 was reimagined to satisfy a growing market of coastal cruisers who demanded more interior volume and traditional aesthetics. By replacing the flush deck with a conventional trunk cabin, Lapworth transformed the boat from a spartan racer into a highly capable family cruiser without sacrificing the nimble performance characteristics that defined the Cal brand. Produced until approximately 1981, the 2-27 remains a staple of the "Classic Plastic" era, prized for its robust construction and balanced sailing manners.

Sailing Performance & Handling
The Cal 2-27 is widely regarded for its "big boat" feel in a compact 27-foot frame. With a displacement of approximately 6,700 pounds and a ballast-to-displacement ratio hovering near 37%, the vessel is notably stiffer and more sea-kindly than many of its lighter contemporaries. This stability is largely attributed to its lead fin keel and relatively deep 4.25-foot draft, which allow it to point well and maintain momentum through a chop.
Under sail, the boat benefits from a masthead sloop rig and a Sail Area/Displacement (SA/Disp) ratio of approximately 16.8. This ratio places the 2-27 in the category of a balanced cruiser-racer—energetic enough to perform in light air while remaining manageable when the breeze freshens. According to editorial insights from Practical Sailor, the Cal 27 hull series is known for being remarkably well-balanced; when trimmed correctly, the boat exhibits minimal weather helm. The spade rudder provides responsive steering, though owners often note that the boat’s tracking is superior to many other fin-keel designs of the 1970s, making it a forgiving platform for solo sailors or novice crews.
Interior Comfort & Variations
The primary differentiator of the "2-27" variant is its trunk cabin, which affords an impressive 6' 2" of headroom—a rarity for a boat of this length during its production run. The layout is a classic example of efficient 1970s yacht design, featuring a V-berth forward, a localized enclosed head to port, and a hanging locker to starboard. The main salon typically utilizes an L-shaped settee that converts into a double berth, with an additional straight settee or pilot berth opposite.
Materials throughout the cabin reflect the Jensen Marine standard of the era: functional teak trim paired with a molded fiberglass headliner. The galley is situated aft, typically featuring a two-burner stove and a deep icebox. The transition from the original Cal 27 to the 2-27 also removed the "pop-top" mechanism found on earlier models, opting instead for structural rigidity and better weatherproofing. Sibling models built on this successful hull include the original Cal 27 (flush deck/pop-top) and the later Cal 3-27, which featured a modernized deck mold and interior refinements. The Cal 2-29, while larger, shares much of the same design DNA and is often compared to the 2-27 by those seeking a bit more waterline.
Known Issues & Buyer’s Checklist
Prospective buyers of a Cal 2-27 must be diligent regarding several era-specific structural concerns common to Jensen Marine builds.
- The "Cal Beam": Perhaps the most critical inspection point is the steel beam located under the cabin sole that supports the mast compression post. In many hulls, this beam was not galvanized or sufficiently encased, leading to rust and eventual structural failure. If the cabin door no longer closes properly or there is a visible "sag" in the deck around the mast step, the beam likely requires replacement.
- Deck Delamination: Like many boats of this vintage, the 2nd generation Cal 27 used a balsa-cored deck. Areas around the chainplates, stanchions, and the mast step are prone to water intrusion. Any "soft spots" discovered during a percussion test indicate a need for core replacement.
- Rudder Moisture: The spade rudder is a hollow fiberglass shell filled with foam. Over decades, water can seep into the core, leading to internal corrosion of the rudder post or delamination of the blade.
- Original Engines: Many 2-27s were equipped with the Universal Atomic 4 gasoline engine or small Farymann diesels. While the Atomic 4 is reliable if maintained, many owners prefer the safety and efficiency of a diesel repower, which can significantly affect the vessel's resale value.
Community & Resources
The Cal 2-27 enjoys a robust following among classic yacht enthusiasts. Technical support and original factory specifications are often archived by the Cal Sailboats Steering Committee, a dedicated group of owners who maintain a repository of manuals, brochures, and historical data for the entire Cal line. Additionally, the design's popularity on the West Coast of the United States has led to active racing fleets and regional owner associations that coordinate "Cal-only" regattas and cruises.
The Verdict
The Cal 2-27 is an enduring example of Bill Lapworth’s ability to blend performance with utility. It remains an ideal choice for the budget-conscious sailor who refuses to compromise on structural integrity or sailing pedigree.
Pros:
- Exceptional headroom (6' 2") for a 27-foot boat.
- Sturdy, heavy-displacement feel that handles coastal conditions with ease.
- Active owner community and high availability of parts/knowledge.
- Balanced sail plan that is manageable for single-handing.
Cons:
- Potential for significant "Cal Beam" structural corrosion.
- Aged systems (plumbing, electrical) often require complete modernization.
- Balsa-cored decks require careful monitoring for moisture intrusion.
