Design Brief & Intent
The Sunwind 33 was conceived to serve a dual mission: to compete dynamically on the Three-Quarters Tonner racing circuit under the International Offshore Rule (IOR) while functioning as a comfortable, thermally efficient family cruiser for the demanding Baltic climate. This dual-purpose intent distinguished it from both the purely spartan racing machines and the heavier, slower cruising vessels of the early 1980s.
To achieve this, the shipyard utilized a vacuum-insulated Divinycell PVC foam sandwich hull construction. This composite technique was highly advanced for its time; it not only provided structural stiffness and lightweight strength but also insulated the living spaces, virtually eliminating the cabin condensation common to solid-fiberglass yachts sailing in cold northern waters.
Below deck, the Sunwind 33 showcases the high-end, hand-finished mahogany joinery that defined classic Finnish yacht building. The interior design is remarkably innovative for a 33-foot envelope, organizing up to six berths across a three-cabin configuration. It features two separate, albeit snug, aft cabins tucked neatly under the cockpit sole, a spacious central salon with comfortable settee berths, an L-shaped galley with dedicated workspace, a commodious midships head on the starboard side, and a traditional V-berth forward. This layout provided family-friendly cruising privacy that was rarely matched by contemporary French or British competitors of similar length.
Variations & Configurations
While the baseline hull mold remained consistent, the Sunwind 33 was built in two primary variations: the standard cruiser and the "RC" (Racing Cruiser) variant. The development of the model was heavily influenced by its prototype, Sunshine, built in 1982. The RC variant carried a taller mast, a high-aspect double-spreader fractional rig, and running backstays designed to optimize mainsail trim and forestay tension in competitive environments. These performance-oriented models earned highly competitive Scandinavian handicap (LYS/SRS) ratings ranging from 1.17 to 1.21.
Underbody configurations across the production run feature a deep, high-performance fin keel drawing approximately 6.14 feet and a balanced, high-aspect spade rudder. The rig is a 7/8 fractional sloop optimized for a self-tacking fock (fock-optimized). This design allows the boat to be easily tacked short-handed when beating to windward, though off-the-wind performance relies heavily on deploying a gennaker or spinnaker to compensate for the smaller headsail area.
Sailing Performance & Handling
On the water, the Sunwind 33 is defined by its stiff, predictable, and highly stable motion in a seaway. Boasting an exceptionally high ballast-to-displacement ratio of 43.59%, the vessel is remarkably rigid, standing up to its canvas and tracking with precision when lesser cruisers are forced to reef. Its generous sail-area-to-displacement ratio of 19.78 translates directly to excellent light-and-medium-wind performance, accelerating quickly and maintaining momentum through lulls.
The yacht's capsize screening formula of 2.17 reflects a design that favors beamier, lighter proportions than classic heavy-displacement double-enders. While highly seaworthy, it is best categorized as a swift regional and coastal passage-maker rather than a dedicated, slow-motion blue-water cruiser. Its comfort ratio of 19.19 indicates a lively, active motion when punching through choppy head seas, demanding an active helmsman to maximize comfort.
The Sunwind 33 was originally designed with tiller steering, which provides an exceptionally direct, tactile feel of the rudder's lift and drag. Although some owners retrofitted steering wheels to mimic larger yachts, veteran Baltic sailors strongly prefer the original tiller configuration. The tiller communicates subtle helm pressure changes instantly, alerts the helmsman to impending broaches under spinnaker, and swings out of the way to open up the spacious cockpit when at anchor.
Market Snapshot & Economics
Because only 14 units of the Sunwind 33 were ever built, the vessel is a rare find on the brokerage market, primarily trading hands within Sweden, Finland, and Denmark. It is highly sought after by regional sailing enthusiasts who value its unique blend of Tord Sundén heritage, Scandinavian build quality, and competitive sailing performance.
The boat consistently commands a pricing premium compared to more common, mass-produced 33-footers of the same vintage. Prospective owners must evaluate the model's economics with its age in mind. While the structural fiberglass work and Divinycell core are highly durable, any purchase will likely require budgeting for modernization, such as updating standing rigging, replacing aging electronics, or repowering the original engine.
Known Issues & Triage
Despite its robust build, several specific areas require close inspection on any surviving Sunwind 33:
- Volvo Penta 2002 Diesel Maintenance: Many hulls were originally equipped with the 18 HP Volvo Penta 2002 inboard diesel engine. If the engine is raw-water cooled, it is highly susceptible to internal cylinder jacket corrosion and cooling passage blockages caused by salt and scale buildup. Additionally, the rubber saildrive diaphragm seal requires a mandatory replacement every seven years; if its history is undocumented, immediate replacement is recommended.
- Deck Moisture Intrusion: While the hull uses a rot-proof Divinycell PVC foam core, Nykra utilized a balsa core for the deck structure. Buyers should use a moisture meter and perform hammer-sounding tests around old deck hardware, stanchion bases, and the mast step. Poorly sealed, aftermarket-installed hardware frequently causes localized balsa rot, demanding tedious core excavation and re-glassing.
- Rigging Complexity: The high-aspect fractional rig, particularly on models utilizing running backstays and double spreaders, requires active tensioning and fine-tuning. For casual family cruising, this rig can feel overly complex and physically demanding compared to a simple masthead rig.
- Draft Limitations: Drawing more than six feet, the Sunwind 33 is restricted from entering shallow harbors, canals, or sandbar-strewn anchorages.
The Verdict
The Sunwind 33 is an elegant, rare, and exceptionally stiff performance cruiser that perfectly captures the spirit of 1980s Scandinavian naval architecture. It is a sailor's boat, rewarding active trimming with impressive speed and precision tracking. While its physical rarity makes finding one a challenge, and its complex fractional rig requires some handiness on deck, its robust thermal insulation, high-end mahogany interior, and remarkable three-cabin layout make it a highly rewarding classic for those who value craftsmanship over mass-market convenience.
Pros:
- Superb structural build featuring a thermally efficient, condensation-resistant Divinycell-cored hull.
- High-quality, traditional Scandinavian mahogany joinery.
- Excellent sailing performance with high initial stability and a stiff, predictable motion.
- Innovative three-cabin layout that maximizes privacy and berthing options in a 33-foot hull.
- Highly responsive and tactile helm feel, especially under the original tiller steering configuration.
Cons:
- Extremely scarce on the global brokerage market, with almost all units concentrated in the Baltic region.
- The double-spreader fractional rig with running backstays can be complex and demanding for short-handed cruising.
- A deep draft of over six feet limits access to shallower cruising grounds and smaller marinas.
- Potential for localized balsa rot in the deck core if aftermarket hardware was poorly sealed.
