Sunwind 33 Information, Review, Specs

Sailing Performance & Handling

The Sunwind 33 is defined by its stiff, seaworthy motion, a direct result of a high ballast ratio of approximately 43%. This makes the vessel remarkably stable in the choppy conditions typical of the Baltic and North Seas. Designed as a fractional sloop, the rig is modern for its time, allowing for easier headsail handling and more precise tuning of the mainsail. According to historical records on Histoiredeshalfs, the model was even developed with racing in mind, with the prototype "Sunshine" (1982) serving as the basis for the subsequent production run.

On the water, the boat tracks with the precision expected of a Sundén design. It features a deep fin keel and a spade rudder, which provide high maneuverability and a tight turning radius. Technical data from regional racing authorities, such as Sailarena, indicates that the "RC" (Racing Cruiser) variant carries a generous sail area relative to its displacement, resulting in a competitive LYS (Scandinavian handicap) rating of 1.17 to 1.21. Owners frequently report that while the boat is a fast performer in medium winds, it remains manageable for short-handed crews due to its balanced helm.

Interior Comfort & Variations

The interior of the Sunwind 33 showcases the high-end mahogany joinery characteristic of 1980s Finnish yacht building. The layout was considered innovative for a 33-foot hull, often featuring two separate aft cabins in addition to the traditional V-berth, allowing for a three-cabin configuration that could sleep up to six adults comfortably. The use of a Divinycell foam core in the hull construction serves a dual purpose: it provides structural rigidity while acting as an effective thermal and acoustic insulator, significantly reducing condensation and noise in the living spaces.

To port of the companionway, the L-shaped galley is typically equipped with a double sink and a gimbaled stove with an oven. Opposite, to starboard, is a surprisingly spacious head for a boat of this size. The central salon features two longitudinal settees with a large folding table. While the Sunwind 33 was the flagship for the Nykra yard during its production, it was part of a larger family of designs, including the Sunwind 27, 29, and the more common Sunwind 31, all of which share the same philosophy of efficient space utilization and "warm" wood finishes.

Popular Mentions & Media

The Sunwind 33 maintains a quiet but dedicated presence in the "Three Quarter Tonner" racing history. Because so few were made, they are often treated as "sleeper" boats in the used market—vessels that outperform modern cruisers while remaining largely unknown outside of Northern Europe. The prototype "Sunshine" is a noted point of interest for maritime historians of the Sundén lineage, marking a transition point where the designer moved from the traditional long-keel Folkboat style toward more performance-oriented fin keel configurations.

Known Issues & Buyer’s Checklist

• Deck Core Integrity: Like many sandwich-constructed boats of this era, the Sunwind 33 uses Divinycell or balsa in the deck. Buyers should check for soft spots around the chainplates and stanchions, as moisture ingress can compromise the core.
• Engine Maintenance: Most units were originally fitted with the Volvo Penta 2002 series diesel (18hp). These are reliable engines but are prone to cold-start issues if the glow plugs or fuel system are not meticulously maintained. Check the Sail Drive seal, which requires replacement every seven years.
• Rigging Age: Given the fractional rig’s reliance on tension, the standing rigging should be carefully inspected. Many of these boats still carry older masts that may need updated spreaders or terminal fittings.
• Tankage Limits: For long-distance cruising, the original fuel (approx. 70 liters) and water (approx. 200 liters) capacities are relatively small. Many owners have since retrofitted additional tanks under the salon settees.

Community & Resources

The most active technical community for this model is the Finnish Sunwind Club (Sunwind-purjehtijat). This association provides deep technical archives and historical context for the Nykra-built models. In Sweden, technical enthusiasts often reference the regional wikis maintained by veteran sailors for specific hardware and sail-plan configurations unique to the Sundén designs.

The Verdict

Pros:

• Excellent build quality with high-end mahogany interiors.
• Stiff and seaworthy performance thanks to the Tord Sundén design.
• Exceptional thermal insulation from the Divinycell sandwich hull.
• Innovative three-cabin layout for a 33-foot vessel.

Cons:

• Extremely limited availability on the second-hand market.
• Original engine systems (Volvo 2002) may be nearing the end of their service life.
• Small fuel and water capacity for extended offshore passages.
