Design and Construction
Södergren's hull is solid fibreglass in sandwich construction, a choice the builder credited with improving the cabin's indoor climate, while the deck is likewise fibreglass and the interior joinery is mahogany hull is a sandwich construction. A lead fin keel and spade rudder sit beneath a 27-foot-3-inch waterline, and the 11-foot-4-inch beam gives a length-to-beam ratio of 3.05. At 9,920 pounds displacement with 4,850 pounds of lead ballast, the 49 percent ballast ratio and moderate 225 displacement-length figure place her among what period analysts called "moderate racers" rather than heavy cruisers. The wetted surface runs about 365 square feet, and the immersion rate of roughly 1,074 pounds per inch speaks to a hull that sits heavily when loaded.
Rig and Handling
The boat carries a fractional sloop rig and a shaft-drive drivetrain turning a single diesel. Her sail-handling geometry is well defined: jib and genoa sheets run about 34.5 feet at 14 mm diameter, the mainsheet is 86.4 feet of 14 mm line, and spinnaker sheets are 76 feet of the same diameter. With a capsize screening value of 2.07, a period review noted she would not be accepted for ocean racing, and the comfort and speed figures describe a stiff, quick coastal boat rather than a bluewater voyager. The draft of 6.4 to 6.7 feet dependent on load limits her to major marinas.
Accommodations
The cabin is trimmed in mahogany in the manner of many European yachts of the era, and the sandwich hull was intended to keep the interior more temperate than a solid layup would. The published material offers no berth count, galley arrangement, or head layout, so the liveaboard plan must be judged hull by hull.
Known Issues
The only cautions are inherent to the design: the deep fin keel restricts anchorage choices, and the capsize screening value bars her from sanctioned offshore racing. A buyer should treat the low production count as a parts-and-reference scarcity issue rather than a flaw.
The Verdict
The Helmsman 35 is a rare, thoughtfully built Scandinavian sloop that pairs a comfortable motion with racy proportions. She suits a sailor who wants a distinctive, well-finished coastal performer and accepts limited marina access and a thin support network.
Pros
- Sandwich fibreglass hull aimed at a better cabin climate
- Lead fin keel with a 49 percent ballast ratio for stiffness
- Mahogany interior and Danish yard construction
- Motion Comfort Ratio of 20.4 to 21.5 for her size
Cons
- Deep 6.4–6.7 ft draft limits marina access
- Capsize screening of 2.07 excludes ocean racing
- Very few built, complicating spares and reference material
