The Storfidra 25 stands as a testament to the Swedish philosophy of building compact, "overbuilt" offshore cruisers. Designed by the renowned naval architect Olle Enderlein and produced by ABC Fabrikerna (AB Bröderna Claesson) in Kungälv during the late 1960s and early 1970s, this 25-foot double-ender was conceived for sailors who prioritized sea-kindliness and safety over raw speed. While ABC Fabrikerna was a diversified manufacturer of sports equipment, the Storfidra represented a sophisticated evolution of their marine line, moving beyond simple open boats into the realm of serious blue-water pocket cruisers. According to the Olle Enderlein Yacht Design Archive, the boat’s design (drawing number 135) emphasizes a traditional long-keel silhouette that has earned it a cult following among solo circumnavigators and coastal traditionalists alike.

Sailing Performance & Handling

The Storfidra 25 is defined by its heavy displacement and high ballast ratio, which provides a level of stability rarely found in modern boats of this length. With a displacement of approximately 3,100 kg (6,834 lbs) on a 25-foot frame, its Displacement/Length (D/L) ratio is exceptionally high, firmly categorizing it as a heavy-displacement cruiser. In practice, this means the boat feels "planted" in the water; it does not skip over waves but rather punches through them with a predictable, rhythmic motion.

Handling is characterized by excellent tracking, a direct benefit of the long keel and the canoe stern, which helps prevent "broaching" when running downwind in heavy seas. However, the trade-off for this directional stability is a lack of agility in light winds. The Storfidra requires a stiff breeze to come alive, and its relatively modest sail area means it can be sluggish in stays (tacking) if momentum is lost. Under sail, the boat feels remarkably secure, often described by owners as a "miniature ship" rather than a yacht. It is a vessel that encourages the crew to set the trim, engage a wind-vane self-steerer, and trust the hull to handle the conditions.

Interior Comfort & Variations

Despite its modest length, the Storfidra 25 offers a surprisingly functional interior, a result of Enderlein’s clever use of the boat's generous beam and high freeboard. The layout typically features a classic Scandinavian arrangement: a V-berth in the forepeak, a compact head located between the main cabin and the forepeak, and two longitudinal settees in the saloon that double as sea berths. The woodwork, often mahogany or teak, reflects the high craftsmanship standards of 1970s Swedish boatbuilding.

One of the boat's most praised features is its headroom, which approaches 1.80 meters (approx. 5'11") in the main cabin—an achievement for a 25-foot double-ender. Ventilation and light are provided by a combination of deck hatches and the signature portlights that define its rugged profile. The Storfidra 25 is the larger sibling to the 20-foot Havsfidra, another Enderlein design. While the Havsfidra is a true "micro-cruiser" with cramped quarters, the Storfidra 25 provides enough volume for two people to cruise comfortably for extended periods, featuring a proper galley and dedicated storage for charts and wet gear.

The Storfidra 25 has carved out a distinct niche in the "small boat, big ocean" community. It is frequently cited in European sailing literature as one of the most capable 25-footers ever built. Numerous Storfidras have completed successful Atlantic crossings, and the model is often discussed on technical platforms alongside other legendary pocket cruisers like the Vancouver 27 or the Falmouth Cutter 22. While it hasn't achieved the mainstream fame of a Contessa 26, it remains a "sailor’s boat," revered in Swedish and German sailing circles for its ability to withstand North Sea gales that would send modern light-displacement boats back to the marina.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Storfidra 25 with an eye toward its age and the specific construction techniques of the early 1970s.

  • Osmosis and Hull Blisters: Like many GRP boats from the 1970s, the Storfidra is susceptible to osmotic blistering. While the hulls were built with thick laminates, any purchase should include a moisture meter check of the hull.
  • Deck Core Integrity: The decks are typically cored, and moisture ingress through poorly sealed hardware (stanchion bases, cleats) can lead to soft spots. This is a labor-intensive repair if the core has begun to rot.
  • Auxiliary Power: Many Storfidras were originally equipped with Volvo Penta MD-series diesel engines. These are reliable but very old; buyers should verify if the engine has been repowered or if parts are still obtainable for the existing unit.
  • Rudder Fittings: As a double-ender with a keel-hung or transom-hung rudder, the pintles and gudgeons are subject to significant stress. Inspect these for play or corrosion, as failure in these components is critical on a blue-water boat.
  • Chainplates: Given the boat's age, the stainless steel chainplates and their mounting points in the hull/bulkheads should be inspected for crevice corrosion or stress cracking.

Community & Resources

The Storfidra benefits from a dedicated European following. The most prominent technical resource is the Olle Enderlein Yacht Design Archive, which maintains historical drawings and specifications. Additionally, the Swedish "Fidra" community (encompassing both Havsfidra and Storfidra owners) remains active through various Scandinavian cruising associations, providing a wealth of shared knowledge regarding restorations and modifications.

The Verdict

The Storfidra 25 is a purpose-built sea boat that sacrifices speed and modern "condo" interior volume for absolute seaworthiness and timeless aesthetics.

Pros:

  • Exceptional heavy-weather stability and tracking.
  • "Overbuilt" hull construction with a high ballast ratio.
  • Surprising interior headroom and storage for a 25-foot boat.
  • Classic, handsome double-ended aesthetic.

Cons:

  • Poor performance in light air and underpowered in drifting conditions.
  • Slow to tack; requires careful sail handling to maintain momentum.
  • Aging systems (original engines and wiring) often require replacement.
  • Heavy displacement makes it difficult to trailer compared to modern 25-footers.
