Design Brief & Intent
The primary mission of the Puma 23 was to serve as an accessible, highly capable pocket cruiser and training platform for coastal waters. Unlike its lighter, trailer-sailer contemporary competitors, such as the early swing-keel American pocket cruisers, the Puma 23 was built with the offshore DNA of Holman & Pye, prioritizing structural stiffness and tracking stability over ease of highway transport. The boat was engineered for the owner who wanted a small, easily managed yacht that did not sacrifice the solid feel of a much larger vessel.
Step down into the cabin, and the boat's cruising intentions become clear. Despite a modest hull length of 22.54 feet, the interior volume is maximized. The layout features a traditional warmth, utilizing varnished mahogany or teak wood trim that contrasts sharply with the stark fiberglass liners of competing production boats of that era. Accommodations include an open V-berth in the forepeak with integrated under-berth storage, a marine chemical or pump toilet tucked beneath the forward bulkhead, a convertible portside dinette table that drops to form a double berth, a starboard galley with a sink and icebox, and a starboard quarter berth extending under the cockpit. Headroom is a predictable compromise at approximately 5 feet 3 inches, but a wide sliding companionway hatch allows the galley and salon to feel open and ventilated when moored.
Variations & Configurations
The model underwent several notable configurations during its production run. The standard model was designed around a deep fin keel drawing 3.87 feet, paired with a substantial rudder hung on a robust skeg—a configuration that maximized tracking and protected the rudder assembly from grounding damage. While the northern European Jaguar 23 variants occasionally featured twin-keel or lifting-keel configurations to accommodate tidal estuaries, the Spanish-built Puma 23s almost exclusively shipped with the fixed fin keel.
Propulsion was another area of historical variation. Original factory models often featured a small, raw-water-cooled single-cylinder Solé Mini-Diesel inboard engine. While these tiny, low-horsepower diesels provided excellent range and reliability when properly maintained, many owners opted to save weight, space, and maintenance complexity by utilizing a transom-mounted outboard bracket with a 6 to 9 horsepower long-shaft motor.
In 1981, Nao-Glass introduced a modernized evolution of the design named the Puma 231. The 231 variant featured subtle modifications to the deck mold, incorporating slightly larger, sleeker acrylic windows and minor refinements to the cockpit ergonomics and running rigging layout before the shipyard was reorganized in the early 1980s.
Sailing Performance & Handling
At the helm, the physical implications of the Puma 23's engineering ratios are immediately apparent. It is a stiff, remarkably forgiving boat that sails with the poise of a larger cruiser. The boat's design has an incredibly high ballast-to-displacement ratio of 50.1 percent, meaning more than half of its 2,970-pound total weight is concentrated in its lead or iron keel. This massive righting moment ensures that the boat resists heeling and carries its sail area comfortably well after lighter, beamy pocket cruisers are forced to reef.
The boat’s displacement-to-length ratio of 240.32 categorizes it firmly as a moderate displacement design. While this means it lacks the rapid acceleration and planing potential of modern, lightweight sportboats, it translates to excellent momentum preservation in choppy coastal waters. The bow easily slices through oncoming waves without getting knocked dead, tracking cleanly off the wind.
With a sail area-to-displacement ratio of 18.97, the masthead sloop rig is powerful enough to keep the boat moving well in light airs. In a blow, the combination of the skeg-hung rudder and the deep fin keel ensures the helm remains balanced, with minimal tendency to round up. The capsize screening ratio of 2.02 puts the vessel right on the edge of ocean-racing classifications. While not intended for multi-week blue-water passages, it is highly stable. The motion comfort ratio of 17.13 suggests that while motion in a heavy seaway will be lively—typical of any 22-foot hull—the heavy displacement and deep ballast damp out the sharpest, most fatiguing jerks.
Market Snapshot & Economics
On the secondary market, the Puma 23 represents an exceptional entry-level value, particularly in Spain, Portugal, and parts of France, where the brand still commands a dedicated cult following 3. Because these boats were constructed with heavy laminate thickness, the structural hulls themselves are incredibly durable, often outliving their hardware and powerplants by decades.
Prospective buyers should anticipate that acquisition costs are relatively low, but the total economics of ownership will depend heavily on the status of the auxiliary power and deck core. Purchasing a vessel with a seized, original inboard Solé engine can quickly lead to a situation where the cost of a modern diesel repower exceeds the market value of the boat. Consequently, models converted to modern outboard power generally command a slight premium due to simplified maintenance and reduced overall weight.
Known Issues & Triage
Despite the bulletproof reputation of the hull laminate, several classic age-related vulnerabilities demand careful triage during any pre-purchase survey. The most critical structural vulnerability centers on the deck-stepped mast compression support. In many early Puma models, the physical load from the mast step is transferred to a timber bulkhead or compression post that rests on a structural floor frame. Over decades of high rig tension, the structural floor can degrade, or water can seep into the deck beneath the mast step, causing the deck to sag and structural bulkheads to shift. Inspectors must closely examine the cabin overhead for cracking, check the mast step on deck for depression, and verify that the cabin doors still align correctly.
The deck itself is balsa-cored, making it susceptible to localized soft spots and rot, particularly around the chainplates, stanchion bases, and bow pulpit. If water has penetrated the balsa core, a localized recoring job from underneath or by peeling the top fiberglass layer will be required.
Hull osmosis is another common issue. The polyester resins utilized by Spanish shipyards in the 1970s are prone to blistering, and older Puma 23s that have spent years in warm Mediterranean waters without a proper epoxy barrier coat are highly likely to exhibit gelcoat blisters. While rarely structurally catastrophic due to the sheer thickness of the hand-laid fiberglass, addressing extensive osmosis requires hauling out, peeling the gelcoat, drying the laminate, and applying a multi-coat epoxy barrier system.
Finally, the keel joint and internal ballast cavity should be inspected. On models where iron ballast was encapsulated in resin within the keel cavity, water entry from the bilge or external grounding cracks can cause the iron to swell and rust internally, sometimes fracturing the surrounding fiberglass casing.
Modernization & Upgrades
Modernizing a Puma 23 typically focuses on simplified single-handed sailing and updated power systems. Many owners choose to replace original, heavy, and unreliable inboard diesels. A highly viable modern alternative is converting to an electric outboard or pod drive, or installing a high-thrust gasoline outboard on a robust, counterbalanced lifting bracket. Removing the old inboard engine and its associated fuel tank, propeller shaft, and exhaust system frees up a massive amount of dry storage space under the cockpit and eliminates the risk of diesel fuel odors and bilge contamination.
The electrical system of the Puma 23 is often ripe for a complete overhaul. Veteran owners routinely rip out old, degraded copper wiring and replace it with marine-grade tinned duplex wire. The addition of a single, lightweight lithium iron phosphate (LiFePO4) battery of 100Ah, paired with a small 50W to 100W flexible solar panel on the hatch garage or deck, easily satisfies the power demands of modern LED cabin lights, a VHF radio, simple sailing instruments, and a small electric cooler.
To enhance short-handed sailing safety, modernizing the running rigging is another common project. Leading the main halyard, jib halyard, and reefing lines aft to the cabin top via deck organizers and modern rope clutches allows the skipper to reef and handle sails entirely from the safety of the cockpit. Installing a modern jib furler is also a highly recommended upgrade that greatly improves the boat's utility as a casual day-sailor or coastal pocket cruiser.
The Verdict
The Puma 23 remains one of the most rugged and seaworthy 23-foot pocket cruisers of its era, combining the traditional offshore design philosophies of Holman & Pye with the heavy, hand-laid fiberglass construction of Nao-Glass. For sailors seeking a stiff, forgiving entry-level yacht that can handle adverse weather without drama, this Spanish classic offers excellent stability and sailing characteristics at a modest cost of entry. However, buyers must be prepared to carefully inspect for age-related structural concerns like mast compression and deck core rot to avoid costly restoration projects.
