The Cal 2-24 arrived in the late 1960s as a sophisticated evolution of the boat that launched Jensen Marine: the original Cal 24. While the first Cal 24 (a C. William Lapworth centerboard design) was a revolutionary midget ocean racer, the "2-24" represented a shift toward the modern fin-keel-and-spade-rudder configuration that would define performance cruising for decades. Built in Costa Mesa, California, this model captures the transition of the Cal brand from experimental wooden-to-fiberglass hybrids into a powerhouse of production performance. It was designed to satisfy the burgeoning Midget Ocean Racing Club (MORC) fleet while offering enough interior utility for a young family to spend a weekend at a Catalina mooring or a Great Lakes cove.

Sailing Performance & Handling

The Cal 2-24 is characterized by the "light and lively" feel that defined Bill Lapworth’s early fin-keel designs. With a displacement of approximately 3,200 pounds and a ballast-to-displacement ratio near 34%, the boat is relatively stiff for its size but remains sensitive to weight placement. The spade rudder, a hallmark of the Lapworth design philosophy seen on the legendary Cal 40, provides the 2-24 with exceptional maneuverability in tight quarters and a responsive helm when going to weather.

Under sail, the boat excels in light-to-moderate air. Because of its generous sail area relative to its displacement, it can maintain momentum through lulls that might stall heavier cruisers of the same era. Owners often note that the boat "tracks" better than contemporary flat-bottomed designs, thanks to the specific profile of its swept-back fin keel. However, like many early fin-keelers, it can become "tender" if over-canvased; reefing the main early—typically around 15 to 18 knots of true wind—keeps the boat on its feet and minimizes weather helm. While it lacks the sheer oceanic momentum of the Cal 30, it offers a dinghy-like tactical experience that makes it a favorite for club racing.

Interior Comfort & Variations

For a 24-foot vessel, the Cal 2-24 offers a surprisingly versatile layout, largely due to its "pop-top" cabin house. This feature was a popular innovation of the era, allowing for standing headroom at anchor by elevating the center section of the coachroof and securing it with a canvas or vinyl enclosure. With the top down, the boat maintains a sleek, low-profile aesthetic that reduces windage and improves visibility from the cockpit.

The interior follows a standard "four-berth" arrangement: a V-berth forward, a small galley area, and twin quarter berths that extend aft under the cockpit seats. Storage is found beneath the berths, though the boat is decidedly a "minimalist" cruiser by modern standards. The 2-24 is often compared to its siblings, specifically the original Cal 24 (centerboard) and the later Cal T/4, which was a more radical IOR-influenced design on a similar waterline. Unlike the T/4, which featured a flush deck and more spartan interior, the 2-24 was marketed as a "true" cruiser-racer with better ventilation and more traditional cabinetry.

Known Issues & Buyer’s Checklist

Prospective buyers should focus on technical areas common to Jensen Marine’s construction methods of the 1960s and 70s.

  1. Deck Core Integrity: Like most Cal models, the 2-24 uses a balsa-cored deck. Check for soft spots around the chainplates, stanchion bases, and the pop-top hardware. Delamination in these areas is common if the hardware hasn't been re-bedded every decade.
  2. The "Cal Beam": While most famous in the Cal 2-27 and Cal 34, the 2-24 also utilizes a structural beam (often wood or metal encapsulated in fiberglass) to support the mast step and rig tension. Inspect the area beneath the mast step for signs of compression or sagging, which can lead to rigging tuning issues.
  3. Pop-Top Mechanism: The lifting hardware and the seals around the pop-top are frequent failure points. Ensure the springs or struts are functional and check for "crazing" in the fiberglass where the lifting arms attach.
  4. Rudder Play: The spade rudder on the 2-24 is unsupported by a skeg. Inspect the rudder post for slop in the bushings and check the blade for "wicking" or water absorption, which can lead to internal core rot or delamination over time.
  5. Chainplates: The original stainless steel chainplates are often found to be pitted where they pass through the deck. Given the age of these vessels, a thorough inspection for crevice corrosion is mandatory before any serious breeze is tackled.

Community & Resources

The Cal 2-24 benefits from a robust and enduring enthusiast base. The Cal Sailboats legacy is preserved through various owner-run technical repositories. While Jensen Marine has long since ceased production, the Cal 24 Association and various regional "Cal Yacht" clubs provide a wealth of archival data, including original sail plans and hardware specifications. Owners often frequent the CruisersForum and SailNet for technical advice, where the collective knowledge on "Lapworth designs" remains a vital resource for maintaining these classic fiberglass hulls.

The Verdict

The Cal 2-24 remains a premier choice for the sailor who values performance and historical pedigree over modern volume. It is a "sailor's boat" that rewards proper trim and offers a direct connection to the water that larger, heavier cruisers often lack.

Pros:

  • Performance: Exceptional light-air speed and responsive spade-rudder handling.
  • Versatility: The pop-top feature provides standing headroom without compromising the boat's sleek lines while sailing.
  • Value: One of the most affordable ways to own a genuine Bill Lapworth design with a racing pedigree.

Cons:

  • Age: Most hulls require significant "re-coring" or rigging updates due to their 50-year-plus lifespan.
  • Headroom: Standing headroom is only available at anchor with the top up; under sail, the cabin is cramped.
  • Weight Sensitivity: Performance suffers significantly if loaded down with heavy cruising gear or oversized outboards.
