The Ockelbo OS19 represents a distinct and relatively rare chapter in the history of the Swedish shipyard Ockelbo-Lundgren, a manufacturer primarily celebrated for its rugged, high-performance motorboats. Introduced in the early 1970s, the OS19 was designed by the legendary Pelle Petterson—the Olympic sailor and prolific naval architect responsible for the Volvo P1800 sports car and the ubiquitous Maxi yacht range. As a 19-foot (5.8-meter) trailerable keelboat, the OS19 was Ockelbo’s attempt to bring their reputation for heavy-duty fiberglass construction into the sailing market. While the yard eventually pivoted back to powerboats, the OS19 remains a cult favorite in Scandinavia for its ability to handle the choppy, unpredictable waters of the Swedish archipelago with more composure than many of its lighter contemporaries.

Sailing Performance & Handling
The sailing characteristics of the Ockelbo OS19 are heavily influenced by Pelle Petterson’s philosophy of creating "forgiving speed." With a displacement of approximately 800 kg and a ballast ratio approaching 45%, the boat is remarkably stiff for its size. This high ballast-to-displacement ratio ensures that the vessel remains upright and controllable when the wind freshens, a quality often cited in historical Swedish maritime archives. The hull features a moderate beam and a relatively deep fin keel for a 19-footer, which provides better tracking and upwind performance than the flat-bottomed dinghies or swing-keelers of the same era.
In light air, the OS19 is competent but not a racer; its robust construction makes it heavier than modern sportboats. However, in a blow, the boat’s sea-kindliness becomes apparent. It does not suffer from the "twitchy" helm often found in small trailer-sailers. Instead, it offers a predictable, steady feel that makes it an excellent platform for solo sailors or those graduating from smaller open boats. The rig is a simple masthead sloop, designed for ease of handling rather than complex tuning, which aligns with its intended use as a coastal weekender.
Interior Comfort & Variations
Despite its modest length, the Ockelbo OS19 features a surprisingly functional cabin, distinguishing it from open-cockpit daysailers. The interior is designed with a "cuddy" philosophy, prioritizing dry storage and basic overnight accommodation. It typically offers four berths in a traditional V-berth and two narrow quarter-berths configuration. While headroom is limited—requiring most adults to sit or crouch—the use of large side windows prevents the cabin from feeling claustrophobic.
Materials reflect the utilitarian standards of 1970s Swedish boatbuilding: molded fiberglass liners are common, accented by teak or mahogany trim. Variations in the interior are largely limited to owner modifications, as the production run was relatively standardized. Because Ockelbo utilized the same heavy-duty GRP (Glass Reinforced Plastic) techniques for the OS19 as they did for their famous DC21 motorboats, the interior structures often remain sound even after decades of use. The boat was occasionally marketed alongside the Monark 540, another Petterson design, though the Ockelbo was generally regarded as the sturdier, more "seaworthy" sibling in terms of lay-up thickness.
Known Issues & Buyer’s Checklist
Prospective buyers should approach the Ockelbo OS19 with an eye toward its age and the specific quirks of 1970s fiberglass production.
- Deck Delamination: Like many boats of this era, the OS19 uses a sandwich construction for the deck. Soft spots, particularly around the mast step and the chainplates, are common indicators of core rot caused by water ingress through improperly sealed fittings.
- Keel Bolt Integrity: Given the age of these vessels, the keel bolts should be inspected for "weeping" or rust streaks inside the bilge. While the OS19 is known for a robust keel-to-hull joint, forty years of grounding or stress can compromise the seal.
- Window Leaks: The original rubber gaskets for the cabin windows are a frequent failure point. Replacing these is a common first project for new owners to prevent interior wood damage.
- Rudder Play: The transom-mounted rudder assembly should be checked for play in the pintles and gudgeons. Excess vibration under sail often traces back to worn bushings in the steering gear.
Community & Resources
While there is no longer an active factory presence for Ockelbo sailboats, the model is supported by a niche community of Scandinavian enthusiasts. Historical technical data and original photographs of the vessel in production can be found through the DigitaltMuseum, which maintains records of Ockelbo-Lundgren’s contribution to Swedish industrial heritage. Owners often find technical overlap with the Pelle Petterson/Maxi yacht associations, as many of the rigging components and design philosophies are shared across Petterson’s early-70s portfolio.
The Verdict
The Ockelbo OS19 is a "little big boat" that offers an entry point into keelboat sailing with the safety margins of a much larger vessel. Its design pedigree and robust construction make it a standout for those who value durability over raw speed.
Pros:
- Exceptional build quality and hull thickness.
- Stable and forgiving handling due to a high ballast ratio.
- Designed by the renowned Pelle Petterson.
- Compact enough for easy trailering and seasonal storage.
Cons:
- Relatively heavy for its size, limiting light-wind performance.
- Interior headroom is restricted to a sitting position only.
- Original parts and specific hardware can be difficult to source outside of Scandinavia.
