Within Storebro’s own range, the Eagle I sat as a more substantial, elegant successor to the popular King’s Cruiser 28. It competed directly with the heavy-displacement Scandinavian cruisers of the era, such as the early designs of Peter Norlin or the classic Folkboat derivatives, yet distinguished itself through its superior volume, exquisite cabinetry, and Enderlein’s signature balance of aesthetic grace and seaworthiness.
Design Brief & Intent
Olle Enderlein designed the Eagle I with a clear mission: to create a highly seaworthy, elegant cruiser that didn't compromise on comfort or speed. At a time when European yachtsmen were pushing further offshore into the North and Baltic seas, the Eagle I offered a secure, deep cockpit and a highly balanced hull form.
The interior is a showcase of traditional Swedish cabinet-making. Rather than the sterile, drop-in liners of the burgeoning fiberglass era, the Eagle I features custom Honduran mahogany joinery. The fit-out is highly functional, utilizing every inch of its moderate beam to provide a cozy, offshore-ready cabin with a dedicated galley, a warm main salon, and a V-berth forward. The warmth of the varnished wood and the attention to ventilation make it a comfortable home port during extended coastal passages.
Sailing Performance & Handling
The sailing characteristics of the Eagle I are defined by its traditional, full-keel underbody and heavy-displacement profile. Boasting a displacement of 7,871 pounds and carrying 3,527 pounds of iron ballast, the vessel possesses a very high ballast-to-displacement ratio of 44.81%. This makes the boat exceptionally stiff, standing up to its canvas far longer than modern fin-keelers.
Its displacement-to-length ratio of 346.26 marks it as a true heavy displacement vessel. At the helm, this translates into a highly predictable, "seakindly" motion in rough water. The boat does not slam into head seas; instead, its fine bow entry and substantial weight allow it to carve through waves with minimal loss of momentum. This comforting motion is mathematically reinforced by a Motion Comfort Ratio of 27.96, ensuring that the crew experiences far less fatigue on long passages than they would on a lighter, more modern platform.
With a capsize screening ratio of 1.75, the Eagle I is well within the safety parameters required for offshore cruising. Its sail area-to-displacement ratio of 16.03 indicates a moderate, sensible masthead sloop rig. While it may require light-air sails to keep moving in a drifting match, once the breeze fills in, the Eagle I slots onto a rail and tracks beautifully, requiring very little helm correction to maintain a straight line.
Market Snapshot & Economics
Owning an Eagle I in the modern era is less an exercise in practical utility and more a labor of preservation. On the brokerage market, these vessels are highly scarce and trade almost exclusively among wooden boat enthusiasts who appreciate Scandinavian design pedigree. They do not command the high prices of modern cruisers, but they hold a steady, classic value that depends entirely on their state of conservation.
The economics of purchasing an Eagle I must take into account the reality of wooden boat ownership. While the initial purchase price of an older mahogany hull is often modest, the ongoing cost of cosmetic maintenance (varnish, paint) and structural triage can quickly exceed the boat's market value. However, for an owner with the skills or budget to maintain a traditional wooden vessel, the Eagle I represents a masterclass in classic sailing heritage that turns heads in any harbor.
Known Issues & Triage
As a traditional wooden boat built in the early 1960s, the primary issues facing the Eagle I are related to the natural aging of its timber and fastenings.
- Fastening Fatigue: The mahogany hull planks are copper-riveted and bronze-screw fastened to steam-bent oak frames. Over sixty years of service, these fastenings can suffer from fatigue, and the oak frames can crack or rot, particularly around the turn of the bilge. A thorough survey should inspect the frames for sistering needs and the fastenings for "pinkness" (a sign of zinc leaching).
- Keel Bolts and Ballast Rust: The 3,527-pound iron ballast keel is secured with keel bolts that must be checked for crevice corrosion. If the iron keel has not been periodically faired and sealed, rust scaling can expand, putting pressure on the garboard planks.
- Deck Leaks: The original teak-laid decks were often fastened over a marine plywood sub-deck. Over time, water can penetrate the teak seams, causing the underlying plywood to rot. Triage typically requires re-seaming the teak or, in extreme cases, stripping the deck back to the deck beams and rebuilding it with modern epoxy-laid plywood and new teak or glass.
Modernization & Upgrades
Modernizing an Eagle I typically centers on making the vessel more reliable and easier to single-hand without compromising its classic aesthetic.
- Repowering: The original auxiliary engine was often a heavy, underpowered single-cylinder Volvo Penta diesel (such as the MD1). Most surviving hulls have been repowered with lightweight, reliable twin-cylinder diesels (like the Beta Marine 14 or 20, or a small Yanmar 2YM15). This switch sheds weight, reduces vibration, and significantly increases reliability under power.
- Electrical System Overhauls: Original wiring on these boats was rudimentary at best. Upgrading to a modern, marine-grade tinned copper wiring harness, installing high-capacity AGM or lithium-iron-phosphate (LiFePO4) batteries, and adding subtle, low-draw LED lighting preserves the classic look while ensuring safe, reliable power management.
The Verdict
The Eagle I (Havsörnen I) is a connoisseur’s cruising yacht. It is built for the sailor who values the silent, solid motion of a heavy wooden hull and the timeless aesthetic of varnished mahogany. While it demands a level of stewardship and maintenance that modern fiberglass boat owners would find daunting, it repays its captain with impeccable heavy-weather behavior, beautiful lines, and an elite connection to the golden era of Swedish boatbuilding.
Pros
- Exceptional motion comfort in a seaway due to its heavy displacement and full keel.
- High-quality traditional Swedish construction featuring premium Honduran mahogany and teak.
- Highly stable and resistant to capsize, with a reassuringly stiff sailing profile.
- Renowned design pedigree by Olle Enderlein, guaranteeing classic, head-turning aesthetics.
Cons
- Requires continuous, intensive maintenance associated with traditional wooden hulls (varnish, paint, fastening checks).
- Heavy displacement and modest sail area make it sluggish in light winds.
- Susceptible to structural issues such as frame cracking, wood rot, and deck leaks if neglected.
- Extremely limited interior volume and headroom compared to modern 31-foot cruisers.
