Design Brief & Intent
The Ohlson 36 was designed for the demanding yachtsman who wanted a competitive ocean racer capable of transitioning into a comfortable family cruiser. In the United States, early models were imported by Olympic gold medalist George O'Day, and subsequently by the prominent yacht brokerage Campbell & Sheehan of Larchmont, New York. To compete against popular American designs of the era, Einar Ohlson relied on traditional Scandinavian boatbuilding artistry.
Constructed primarily in Sweden by elite yards on the island of Orust, including Bröderna Gustavsson and Martinsson, the hull featured carvel-planked Honduras mahogany on steam-bent or laminated oak frames 4. The fit-and-finish was exemplary, showcasing a level of wooden joinery that was cost-prohibitive for domestic American builders. Below deck, the design was optimized for safety at sea. The cabin arrangement typically featured four to six berths, deep mahogany fiddles on all flat surfaces, and robust handholds. The warmth of the varnished mahogany interior, combined with a practical layout featuring a secure galley, dedicated navigation station, and functional head, made the Ohlson 36 a cozy sanctuary during long offshore passages.
Variations & Configurations 1
Einar Ohlson designed the Ohlson 36 with inherent versatility, offering it in both masthead sloop and yawl configurations. The yawl rig featured a mainmast and a small mizzen mast stepped aft of the rudder post. While the sloop was preferred for pure windward performance, the yawl rig gained immense popularity in the United States. The mizzen sail allowed for superior balance under canvas, simplified shorthanded handling by allowing the mainsail to be dropped while maintaining steerage under "jigger and jibe," and offered the ability to fly a mizzen staysail for added power off the wind.
The design underwent a significant revision in 1964 with the introduction of the Mark II version 6. While the original hulls possessed a beam of 9.33 feet, the Mark II featured a slightly widened hull with a beam of 9.67 feet. This change increased initial stability and provided more interior volume without sacrificing the boat's slippery profile. The Mark II also received updated frames, minor keel modifications, and an improved rudder profile to enhance steering response.
Sailing Performance & Handling
Under sail, the Ohlson 36 exhibits the predictable, kindly motion typical of classic heavy-displacement cruiser-racers. With a displacement of 13,800 pounds and a short waterline length of 25.0 feet, the boat has a high displacement-to-length ratio of 394.29. This heavy hull profile ensures that she does not bounce or shudder in chop; instead, she slices cleanly through head seas, preserving forward momentum. The motion comfort ratio of 38.48 confirms this physical reality, indicating an exceptionally soft, steady ride that minimizes crew fatigue over long passage distances.
The boat’s safety margins are similarly robust, with a capsize screening ratio of 1.56, signifying that the hull is highly resistant to rollover and possesses outstanding self-righting capabilities. At the helm, the ballast-to-displacement ratio of 36.23 percent contributes to a stiff, stable feel. When the wind rises, the boat heels to a comfortable angle and locks in, tracking straight with very little rudder correction.
With a sail area-to-displacement ratio of 14.89, the rig is conservative by modern standards, which can make the boat feel slightly underpowered in light air. However, Einar Ohlson’s Olympic-derived hull lines feature incredibly fine entries and an elegant run aft, which minimizes drag 1. This allows the Ohlson 36 to slip along surprisingly well in light breezes where other heavy-displacement hulls of her era would stall.
Market Snapshot & Economics
Decades after the last hull left the Orust shipyards, the Ohlson 36 occupies a unique niche in the classic brokerage market. Because nearly all of the 140-plus hulls were exported to the United States, they are occasionally found on the East and West coasts. These boats trade at a relative value compared to fiberglass classics, as the market pricing heavily discounts wooden hulls due to the ongoing maintenance they require.
An Ohlson 36 in need of major structural work can often be acquired for a very low entry price, but buyers must be warned that the economics of a professional wooden yacht restoration can easily eclipse the vessel's eventual market value. Conversely, well-maintained or fully restored examples command a premium among wooden boat purists and classic yacht racers. Owning an Ohlson 36 is an act of stewardship; those willing to invest the time and money into annual brightwork and structural preservation will own a piece of maritime history that turns heads in any harbor.
Known Issues & Triage
Prospective buyers must approach the Ohlson 36 with a clear understanding of vintage wooden yacht construction. The most significant technical issue stems from her specific "glued-seam" carvel planking. While this method produced exceptionally smooth hulls that did not require traditional caulking, it introduces a severe structural risk if the boat is allowed to dry out extensively on land. When a dry hull is returned to the water, the mahogany planks swell. Because the edge-glued seams do not compress easily, the expansion forces are transferred directly to the oak frames, which can result in cracked or fractured frames.
Another area requiring close inspection is the fastening system. The planks were fastened with copper rivets, which can suffer from metal fatigue or pull through soft wood over sixty years of hard sailing. Frame heads, particularly around the chainplates and deck-to-hull joints, are highly vulnerable to rot caused by freshwater leaks from the deck. Additionally, the massive wood keel timber, stem, and horn timber must be thoroughly checked for soft spots and rot, as repair of the backbone structure requires highly skilled shipwright labor.
Modernization & Upgrades
Most surviving Ohlson 36s have undergone significant modernization to remain viable and reliable cruising yachts today. The original powerplants, which often included raw-water-cooled Albin or Graymarine gasoline engines, or even tiny auxiliary two-strokes like the Vire engine, are now universally obsolete. The standard modern upgrade is a complete repower with a lightweight, fresh-water-cooled diesel engine, such as a 25-to-30 horsepower Beta Marine or Volvo Penta unit. This repower not only dramatically improves reliability and safety but also adds necessary weight down low.
Veteran owners have also modernized the boat's electrical systems. The original wiring is typically replaced with modern marine-grade tinned copper wire, high-output alternators, and increasingly, lithium iron phosphate battery banks. Due to the limited space aboard, some owners have opted for composting toilets to eliminate the complex plumbing and raw-water intakes of vintage marine heads. Canvas-covered wood decks, which were a common source of freshwater leaks, are frequently replaced or overlaid with modern fiberglass-encapsulated marine plywood to permanently seal the hull structure from moisture.
The Verdict 2
The Ohlson 36 remains one of the finest examples of mid-century Swedish yacht design, offering an unparalleled blend of classic beauty, sea-kindly handling, and historic pedigree. She is a true sailor's yacht, rewarding her helmsman with exceptional tracking and a gentle motion that modern flat-bottomed fiberglass boats cannot replicate. However, she is not a boat for the casual weekend sailor. Owning an Ohlson 36 requires a deep commitment to the craft of wooden boat maintenance. For the dedicated steward, she is a rewarding, capable bluewater cruiser that continues to live up to her legendary title as "The Racing Machine".
