Scanmar 31/31 A Information, Review, Specs

Sailing Performance & Handling

The Scanmar 31 is defined by its 7/8 fractional rig, a configuration favored by Rolf Magnusson for its balance and ease of tuning. This setup, often paired with a self-tacking jib, makes the boat exceptionally easy to handle for short-handed crews. The hull features a relatively deep fin keel and a spade rudder, providing a high degree of maneuverability in tight quarters and responsive steering on the wind. With a displacement-to-length ratio that leans toward the lighter side of traditional cruisers, the 31 is known for its ability to accelerate quickly in light airs, yet it maintains enough form stability to handle the choppy conditions of the North Sea or the Baltic.

According to technical archives from the Scanmar Owners Association, the boat’s ballast ratio is approximately 40%, which contributes to its reputation for being "stiff" and capable of carrying full sail longer than many of its contemporaries. Owners frequently report that the boat tracks exceptionally well, requiring minimal helm correction when properly trimmed. The cockpit ergonomics are optimized for sailing, with primary winches positioned within easy reach of the helmsman, reinforcing the boat’s identity as a sailor’s yacht.

Interior Comfort & Variations

True to the vision of Scanmar founder Nils-Erik Olofsson, the interior of the Scanmar 31 punches well above its weight class. By utilizing a wide beam carried relatively far aft, Magnusson was able to incorporate an interior volume typically found in vessels three to four feet longer. The layout is centered around a traditional salon with a central table and flanking settees, but the hallmark of the design is the innovative use of space in the extremities.

The Scanmar 31 was one of the first in its size range to offer a genuine aft cabin that didn’t feel claustrophobic, a feat achieved by tucking the berth under the cockpit sole while maintaining adequate ventilation. The "A" variant often features slight improvements in the galley ergonomics or a revised navigation station. Throughout the cabin, the use of high-quality teak veneers and solid wood trim reflects the premium Swedish craftsmanship of the era. Headroom is generous, often exceeding six feet in the main salon, ensuring that the living spaces remain comfortable for extended coastal cruising.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Scanmar 31 with a focus on the specific mechanical and structural components common to Swedish builds of the 1980s.

• Saildrive Diaphragm: Most Scanmar 31s were originally fitted with Volvo Penta engines and S-drives. It is critical to check the age of the rubber hull seal (diaphragm). Manufacturers typically recommend replacement every seven years, though many boats on the market are well past this interval.
• Deck Core Integrity: While Scanmar used high-quality construction methods, the decks are sandwich-constructed (often with balsa or foam). Areas around stanchion bases and chainplates should be inspected with a moisture meter for signs of delamination or water ingress.
• Rigging Age: Given the age of these vessels, the standing rigging must be scrutinized. If the boat still carries its original Selden mast and stainless rigging, a professional swage inspection is mandatory.
• Rudder Bearings: The spade rudder design can develop "play" over decades of use. Check for excessive movement in the rudder stock, which may indicate worn bushings or bearings.
• Keel-to-Hull Joint: Inspect the "smile" at the leading edge of the keel. While the Börjesson Brothers built robust boats, grounding incidents can lead to structural weeping or weakened floor timbers near the keel bolts.

Community & Resources

The Scanmar brand maintains a small but highly technical following, primarily centered in Northern Europe and the United Kingdom. The most prominent resource for technical drawings, spare parts sourcing, and owner manuals is the Scanmar Owners Association, which provides a wealth of information on both the 31 and 33 models. Additionally, because many components (masts, engines, and hatches) were sourced from major Swedish suppliers like Selden and Volvo Penta, technical support for the hardware remains readily available compared to other defunct builders.

The Verdict

The Scanmar 31 and 31 A remain highly desirable on the pre-owned market for sailors who prioritize build quality and sailing dynamics over "caravan-style" interior volume. It is a boat that rewards a skilled hand on the tiller while providing a safe, dry environment for a small family.

Pros:

• Superior Swedish build quality and interior woodwork.
• Excellent upwind performance and light-air responsiveness.
• Easy to sail short-handed due to the fractional rig and self-tacking jib options.
• Timeless aesthetic that avoids the "boxy" look of modern high-volume cruisers.

Cons:

• Older Volvo Penta engines may require modernization or expensive parts.
• Limited availability in the North American market.
• Small cockpit by modern "entertaining" standards, prioritized for sailing efficiency.
