Sunwind 311 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Sunwind 311 is characterized by the stiffness and predictable tracking expected of a Tord Sundén design. It features a fractional rig with a self-tacking jib setup on many hulls, a configuration that emphasizes ease of handling for short-handed crews. The boat’s displacement-to-length ratio suggests a sturdy, moderate-heavy vessel that excels when the wind picks up, maintaining a high degree of "sea-kindliness" in a chop.

The hull utilizes a fin keel and a skeg-hung rudder, providing a balance between maneuverability and directional stability. While it may not match the light-air acceleration of modern Mediterranean-style cruisers, it remains a formidable performer on a beat. According to technical archives from the Finnish boating publication Vene-lehti, the 311 is noted for its ability to carry sail longer than its competitors without becoming overpowered, a trait attributed to its generous ballast ratio. The 7/8 fractional rig allows for precise mainsail trimming, giving the helm a responsive, tactile feel that appeals to sailors who enjoy active tuning.

Interior Comfort & Variations

The interior of the Sunwind 311 showcases the high standard of Finnish carpentry, typically finished in warm, satin-varnished teak. The layout is optimized for a family of four to five, featuring a traditional V-berth forward, a central salon with twin settees, and a functional L-shaped galley. Unlike its predecessor, the Sunwind 31, the 311 often featured an updated aft-cabin arrangement or a more spacious quarter berth, depending on the specific year of production and owner customization.

The use of a sandwich construction for the deck and coachroof provides excellent thermal and acoustic insulation, which is a critical feature for Northern European sailing. Headroom is generous for a 31-foot boat of this vintage, typically clearing six feet in the main cabin. Storage is a notable strength; the Sunwind 311 was designed for "proper" cruising, meaning lockers are deep and dry, with ventilation integrated into the cabinetry to prevent the condensation issues common in lesser-built vessels.

Known Issues & Buyer’s Checklist

Prospective buyers of a Sunwind 311 should focus their inspections on the specific aging points common to 1980s Finnish builds. While the hulls are generally solid GRP, the deck is a balsa-core sandwich construction; any poorly sealed hardware—such as stanchion bases or cleat mounts—can lead to localized core rot. A "thump test" or moisture meter reading across the deck is essential.

The original powerplants were often Volvo Penta 2000-series engines mated to S-drive transmissions. The S-drive diaphragm requires replacement every seven years per manufacturer recommendations, and many older units may still be running on overdue seals. Additionally, because the 311 uses a fractional rig with swept-back spreaders, the chainplates and the mast step area should be inspected for stress fractures or signs of compression, especially if the boat has been campaigned in club racing. Finally, check the rudder bearings; while the skeg provides protection, the bushings can develop play over decades of use, leading to a "clunking" sensation at the helm.

Community & Resources

The Sunwind 311 benefits from a dedicated following in Northern Europe. The most prominent resource for technical data and historical context is the Finnish Sunwind Purjehtijat (Sunwind Sailors Association). This organization maintains archives on rigging specs, original brochures, and modification guides provided by former factory workers and long-term owners.

The Verdict

The Sunwind 311 remains a highly regarded cruiser for those who value build quality and heavy-weather performance over contemporary "condo-maran" volume. It is a robust, honest boat that reflects the rigorous standards of Finnish maritime heritage.

Pros:

• Excellent build quality with superior teak joinery.
• Stable and predictable handling in heavy weather.
• Efficient fractional rig that is easy to manage solo or shorthanded.
• Strong resale value in Scandinavian and Baltic markets.

Cons:

• Slightly slower in light winds compared to modern fin-keelers.
• Aging Volvo Penta S-drives require diligent maintenance.
• Balsa-core decks are susceptible to moisture if deck hardware is neglected.
