About the Ohlson 41 Sailboat

Designed by renowned Swedish naval architect Einar Ohlson in 1965, this classic 41-footer represents a rare example of Scandinavian craftsmanship with only three hulls ever constructed. The limited production run makes this vessel particularly sought after among collectors and sailors who appreciate distinctive design heritage. With a displacement of 20,000 pounds and substantial ballast-to-displacement ratio, the Ohlson 41 offers impressive stability and seaworthiness for extended coastal cruising and offshore passages. The fin keel configuration with rudder on skeg provides excellent tracking and maneuverability while maintaining the directional stability that Ohlson designs are known for. Her moderate beam of 11 feet strikes an ideal balance between interior volume and sailing performance. The masthead sloop rig delivers 738 square feet of working sail area, creating a well-balanced sail plan that's manageable for small crews yet powerful enough for spirited sailing. Her comfort ratio of 39.34 indicates motion characteristics well-suited for long-distance cruising, while the capsize screening value of 1.62 reflects good stability for offshore work. Construction methods varied among the three hulls built, incorporating wood, steel, and fiberglass—a testament to the design's adaptability. This versatile cruiser appeals to sailors seeking a unique vessel with proven seakeeping abilities and timeless Scandinavian styling.
