Design Brief & Intent
The core mission of the Puma 24 was to provide a capable, seaworthy pocket cruiser that could act as a gateway to offshore sailing for growing middle-class families in Spain and Europe. To achieve this, Cabal designed a hull featuring traditional 1970s design aesthetics: a pronounced bow overhang, an elegant narrow reverse transom, a high freeboard, and a low-profile cabin trunk. Unlike its competitor, the French-built Dufour 24, which favored flat-water speed and high interior volume, the Puma 24 focused on solid ocean-going geometry.
The hull was laid up with exceptionally thick, hand-laminated fiberglass, a trademark of early Inerga builds that made the structure nearly bulletproof at the cost of added weight. Below deck, the interior joinery reflects the traditional aesthetics of the era, utilizing extensive teak veneers and solid wood trim. However, the construction relies heavily on structural fiberglass inner molds (contra-moldes), which gave the yacht a clean interior look and simplified assembly, but at the cost of structural transparency and easy access to hidden spaces. This was a boat designed to handle tough Mediterranean conditions—a true mini-cruiser rather than a simple day sailer.
Sailing Performance & Handling
On paper, the Puma 24 displays the traits of a traditional, medium-displacement cruiser. Weighing in at 3,638 pounds, with a generous cast-iron fin keel carrying an estimated 1,430 pounds of ballast, the boat boasts a ballast-to-displacement ratio near 40 percent. This translates directly to an exceptionally stiff feel under sail, allowing the boat to carry canvas far longer than other modern 24-footers before requiring a reef. The displacement-to-length ratio of 235.67 confirms its moderate displacement pedigree, giving the hull a secure, predictable motion in a seaway.
Under sail, the masthead sloop rig provides a respectable sail-area-to-displacement ratio of 17.31, making the boat lively in light to moderate breezes when paired with the right inventory. The motion is characterized by the comfort ratio of 15.45, which, while lively compared to a 30-foot cruiser, is remarkably stable for a 24-foot hull. However, early production versions earned an undeserved reputation for being heavy and "ardiente" (carrying excessive weather helm). Modern fleet experience has demonstrated that this was not a fundamental flaw of the hull design, but rather a consequence of the baggy, deep-draft sails supplied by the factory.
When tracking, the deep 4.92-foot draft allows the Puma 24 to point remarkably high, cutting cleanly through chop rather than pounding over it. Under power, handling becomes more idiosyncratic. With the propeller situated extremely close to the rudder blade, prop wash creates noticeable helm vibration and a severe prop walk. With a standard clockwise-turning propeller, backing up to starboard can be sluggish and frustrating, while backing to port is incredibly sharp, requiring a deliberate hand on the tiller.
Accommodations & Interior Layout
Stepping down the companionway, the Puma 24 offers a surprisingly dense layout that sleeps up to five people. Forward, a classic double V-berth occupies the bow. A marine toilet is situated beneath the center cushion of the V-berth, providing a semi-isolated head arrangement that was standard for the era but lacks the privacy of a dedicated compartment. The main salon is dominated by twin linear settee berths running along the port and starboard sides, with a fold-down centerline table. A single quarter berth (conejera) tunnels under the starboard cockpit locker, which serves as an excellent berth while underway.
The galley is located immediately to port of the companionway, housing a simple single-burner stove, a molded sink, and a deep, insulated icebox built directly into the countertop. The interior headroom is limited to approximately 1.70 meters (5 feet, 7 inches), requiring average-to-tall sailors to stoop. Storage is plentiful, though much of it is tucked into deep recovecos (nooks) and under-settee lockers that can be challenging to access due to the extensive fiberglass inner liner.
Known Issues & Triage
For those looking to acquire a vintage Puma 24, several critical areas require careful inspection. Foremost is the risk of osmosis. While early Inerga hulls are thick, boats produced during the mid-to-late 1970s used polyester resins that are highly susceptible to blistering if left in warm, high-salinity waters without a barrier coat. Buyers should budget for a haul-out and a moisture-meter survey of the underwater profile.
The deck construction utilizes a balsa wood core for stiffness, which is prone to rot around stanchion bases, chainplates, and the mast step. Any soft spots on the deck indicate water intrusion and structural degradation of the core, requiring localized recoring from above or below.
Mechanically, many Puma 24s were fitted with single-cylinder Sole Diesel inboard engines (such as the Sole Mini 3). These engines are incredibly reliable but generate violent vibrations at idle. Over time, these vibrations can loosen engine mount bolts, degrade the shaft log or stuffing box, and cause fatigue cracks in the exhaust system.
Another specific owner complaint centers on system accessibility. The integrated fresh-water tank is located beneath the salon sole and is sealed by a heavy fiberglass cover secured by up to 40 individual screws, making routine inspection and cleaning an incredibly tedious chore.
Modernization & Upgrades
Upgrading a Puma 24 can turn this classic pocket cruiser into a highly dependable, easy-to-manage coastal yacht. The single most impactful upgrade is replacing aged Dacron sails with a modern, flat-cut sail plan. Transitioning to flat-cut sails completely alleviates the heavy weather helm, allowing the boat to reach its theoretical hull speed of nearly six knots in moderate conditions with minimal effort.
For the rig, owners frequently retrofit a reliable genoa furler (such as a Furlex 100S) to replace traditional hank-on head sails, simplifying single-handed sailing. Running rigging is also commonly led aft to the cockpit, which requires adding deck organizers and clutches to the cabin roof.
Drivetrain modernization is also common. Many owners choose to replace the vibrating single-cylinder engines with modern twin-cylinder diesels, such as a 10-to-14 horsepower Sole or Yanmar engine. Due to the boat's compact size and relatively low power demands, the Puma 24 is also an excellent candidate for an electric propulsion conversion, utilizing a 5kW pod or shaft-drive motor powered by a modest lithium-iron-phosphate (LiFePO4) battery bank.
The Verdict
The Puma 24 is a ruggedly built, classic Spanish pocket cruiser that punches well above its weight class in terms of heavy-weather capability and stiffness. While it lacks the interior volume and modern open-transom layout of newer designs, its thick laminate schedule, traditional lines, and robust sea motion make it an incredibly secure platform for novice sailors and veteran pocket-cruisers alike. With proper sail trim and targeted system updates, this vintage cruiser remains an outstanding value on the secondary market.
Pros:
- Extremely stiff and stable under sail due to a high ballast-to-displacement ratio
- Solid hand-laminated fiberglass construction with a thick hull profile
- Capable and comfortable sea motion that handles rough conditions exceptionally well
- Compact, low-maintenance size that fits into affordable 8-meter marina slips
- Five berths provide remarkable sleeping capacity for a 24-foot vessel
Cons:
- Limited interior headroom (1.70 meters) can feel cramped for taller sailors
- Propeller placement causes significant prop walk and sluggish steering in reverse
- Fiberglass inner mold (contra-molde) severely limits access to the hull interior and plumbing
- Original factory sail plans suffer from deep drafts that cause heavy weather helm
- High susceptibility to hull osmosis and deck balsa rot if neglected
