The Ohlson 36 Mk II represents a pinnacle of the "Golden Age" of Swedish yacht design, emerging from the drafting boards of Einar and Carl-Eric Ohlson. While the brothers gained international fame for their 5.5-meter Olympic designs, the Ohlson 36 was their answer to the demand for a seaworthy, offshore-capable cruiser-racer that maintained the aesthetic grace of a wooden hull while embracing the then-emerging technology of fiberglass (GRP). Most hulls were molded by the Tyler Boat Company in the United Kingdom, renowned for their robust laminates, and frequently finished by high-end yards such as Matthiessen & Paulsen in Germany or various Swedish craftsmen. The Mk II designation generally refers to the refined production runs that featured standardized GRP internal modules and improved deck layouts compared to the earliest wood-to-fiberglass transition boats.

Sailing Performance & Handling
The Ohlson 36 Mk II is defined by its deep-V hull sections and a traditional long keel with a cutaway forefoot, a configuration that prioritizes directional stability and a smooth motion in a seaway. With a displacement-to-length ratio that leans toward the "heavy" end of the spectrum by modern standards, the boat possesses significant kinetic energy once under moving, allowing it to punch through coastal chops that would stall lighter contemporary designs.
On the wind, the 36 Mk II is widely regarded as a stellar performer. Its narrow beam—a hallmark of the era—reduces wetted surface area when heeled, allowing the boat to find a "groove" where it tracks with minimal helm pressure. According to historical technical summaries from the Ohlson Yachts archive, the design was specifically optimized for windward efficiency, a trait that helped the model secure numerous podium finishes in mid-century offshore races. However, this same narrow beam and heavy displacement mean the boat is not a "planing" hull; downwind performance is steady and controlled rather than explosive. The rudder, often mounted on a sturdy skeg, provides excellent feedback to the sailor, though the turning circle is predictably wider than that of a modern fin-keel spade-rudder yacht.
Interior Comfort & Variations
Inside, the Ohlson 36 Mk II reflects the transition from utilitarian racing machines to comfortable coastal cruisers. The layout typically features a classic offshore arrangement: a compact galley and navigation station flanking the companionway to keep the weight centered, followed by a settee-lined salon and a forward V-berth. Because many of these boats were finished as semi-custom projects, the quality of the joinery is often exceptional, featuring hand-fitted mahogany or teak.
The Mk II saw more standardization in the head (lavatory) arrangement and storage lockers. Headroom is adequate for the era, generally hovering around 6 feet in the main salon, though it tapers forward. Sibling models often cause confusion in the secondary market; the Ohlson 36 shares a clear DNA with the Ohlson 35 (which featured a different transom and slightly less volume) and the later, highly successful Ohlson 38. While the 38 offered a more modern fin-and-skeg arrangement and increased beam, the 36 Mk II is often preferred by traditionalists who prioritize the balanced, predictable handling of a more conservative underwater profile.
Popular Mentions & Media
The Ohlson 36 holds a storied place in the history of the "Gentleman’s Racer." While specific individual "celebrity" boats are rare, the model is frequently cited in classic yachting literature as a benchmark for Scandinavian seaworthiness. The design’s reputation was bolstered by the success of the Ohlson brothers’ other designs in the 5.5-meter class, which brought a level of prestige to their production cruisers. The boat is a recurring subject in retrospective reviews by Yachting Monthly, where it is often compared to the Nicholson 32 and the Rustler 36 as a premier choice for long-distance blue-water cruising on a budget.
Known Issues & Buyer’s Checklist
Prospective buyers of an Ohlson 36 Mk II should approach the purchase with an eye toward the structural longevity of 50-year-old fiberglass and wood.
- Deck Core Integrity: Like many boats of this vintage, the decks are often a sandwich construction. Over decades, hardware such as stanchion bases or cleat bolts can leak, leading to moisture ingress and delamination of the balsa or plywood core. A percussion test (hammer sounding) across the side decks is essential.
- Chainplates and Rigging: The original stainless steel chainplates are often glassed into the hull or bolted through thick reinforcements. These should be inspected for crevice corrosion, especially where they pass through the deck.
- The "Tyler" Hull Osmosis: While Tyler Boat Co. produced very thick hulls, some Ohlson 36s have shown susceptibility to osmotic blistering. While rarely structural due to the thickness of the laminate, it is a significant factor in resale value and maintenance overhead.
- Engine Replacement: Many Mk IIs were originally fitted with Volvo Penta or Westerbeke diesel engines that have likely reached the end of their service life. Buyers should check if a modern Yanmar or Beta Marine repower has been performed, as the engine room access is notoriously tight.
- Rudder Bushings: The skeg-hung rudder is robust, but the bushings at the base and the entry point to the hull can wear, leading to vibration or "play" in the steering system.
Community & Resources
Owners of these vessels are supported by a dedicated, albeit decentralized, community of classic yacht enthusiasts. The most prominent resource is the Ohlson Yachts technical archive, which maintains historical drawings and specifications. Additionally, the Ohlson Owners group—often found through classic boat registries in the UK and Scandinavia—serves as a vital hub for sourcing specific hardware or advice on restoring the vessel's signature wooden brightwork.
The Verdict
The Ohlson 36 Mk II is an "honest" yacht—it does not pretend to be a spacious floating apartment, nor a modern ultra-light racer. Instead, it offers a level of aesthetic beauty and heavy-weather capability that is increasingly rare.
Pros:
- Timeless Aesthetics: One of the most beautiful profiles of the GRP era.
- Seaworthiness: Exceptional tracking and a "kind" motion in heavy seas.
- Build Quality: High-quality Swedish and British craftsmanship ensures longevity if maintained.
Cons:
- Interior Volume: Narrow beam results in a cramped interior compared to modern 36-footers.
- Maintenance: Significant exterior teak and aging systems require an active maintenance schedule.
- Maneuverability: The long-keel design makes backing into tight slips under power a challenge for the uninitiated.
