Winga Mix 31 MS Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the Winga Mix 31 MS are markedly improved over its sibling, the Winga 87, primarily due to a lower center of gravity and a more generous sail plan. With a displacement-to-length ratio that sits firmly in the moderate cruiser category, the Mix 31 is a stable, sea-kindly platform that handles chop with the predictable motion characteristic of Swedish hulls of this era.

Under sail, the boat benefits from a well-proportioned masthead sloop rig. While it is not a light-air performer—owing to its relatively high wetted surface area and substantial beam—it comes into its own in a stiff breeze. Owners often report that the boat feels "stiff," meaning it resists excessive heeling, which is a byproduct of its generous beam and internal ballast. The steering is typically handled by a tiller, providing more direct feedback than the hydraulic wheel systems found on many motorsailers, allowing the helmsperson to feel the balance of the boat. The inclusion of a fin keel and a spade rudder gives the Mix 31 a tighter turning circle and better maneuverability under power than the long-keeled motorsailers of the previous decade.

Interior Comfort & Variations

The interior of the Winga Mix 31 MS is a masterclass in 1980s Scandinavian joinery, typically finished in high-quality mahogany or teak. Because the "Mix" version moved the cockpit aft, the interior volume is surprisingly expansive for a 31-foot boat. The layout generally features a V-berth forward, followed by a full-width head and a spacious main saloon. The saloon often utilizes a U-shaped settee to port and a straight settee to starboard, providing ample seating for a full crew.

The galley is a highlight, usually positioned near the companionway for ventilation and ease of access to the cockpit. It typically features a deep sink, two-burner stove, and significant locker space, reflecting the boat's intended use as a serious coastal cruiser. One of the most notable variations of this hull is its sibling, the Winga 87, which features a completely different deck mold with an enclosed pilothouse and an aft cabin. In contrast, the Mix 31 provides a more open, social cockpit experience while maintaining excellent headroom (often exceeding 6 feet) throughout the main cabin.

Known Issues & Buyer’s Checklist

Prospective buyers of a Winga Mix 31 MS should focus their inspections on the specific aging points of Swedish GRP construction from this era:

• Volvo Penta Engine & Saildrive: Most Mix 31s were originally fitted with Volvo Penta diesel engines (often the MD11 or 2000 series) and saildrives. It is critical to check the age of the rubber saildrive seal; if it is more than seven years old, it requires replacement. Additionally, check the exhaust elbow for carbon buildup or corrosion.
• Deck Core Integrity: While Winga used solid glass for many areas, the decks are often cored. Buyers should use a moisture meter or perform a "tap test" around the chainplates, mast step, and stanchion bases to ensure no water ingress has softened the core.
• Window Seals: The large forward-facing saloon windows are a signature Winga design element, but they are prone to leaking over time. Look for water staining on the interior woodwork beneath these windows.
• Rigging and Chainplates: Many of these vessels still carry their original standing rigging. Given the age, a professional shroud replacement is often necessary. Inspect the chainplates where they pass through the deck for signs of "tea staining" or crevice corrosion.

Community & Resources

The Winga brand enjoys a dedicated following, particularly in Northern Europe and the United Kingdom. Technical support and owner knowledge are primarily concentrated in the Winga Owners Association (Wingaägarna), a Swedish-based group that provides technical documentation, original brochures, and a forum for restoration advice. While the organization is primarily Swedish-speaking, they are a vital resource for sourcing specific replacement parts or understanding the original build specifications of the Bruno Boström designs.

The Verdict

The Winga Mix 31 MS is an excellent choice for a small family or couple looking for a robust, high-volume cruiser that prioritizes safety and comfort over racing pedigree.

Pros:

• Exceptional interior volume and headroom for its length.
• High-quality Scandinavian craftsmanship and durable GRP construction.
• Predictable and stable handling in heavy weather.
• More "sailable" than traditional motorsailers while retaining high engine reliability.

Cons:

• Sluggish performance in light winds due to weight and wetted surface.
• Access to certain hull areas can be tight due to the expansive interior furniture.
• The large windows can lead to "greenhouse" heating in warmer climates without proper ventilation.
