The Sunwind 27, designed by the prolific Swedish naval architect Tord Sundén, represents a significant chapter in Finnish yacht building from the late 1970s and early 1980s. Produced by Oy Sunwind Ab, this model was conceived as a family-friendly coastal cruiser that could handle the choppy, unpredictable conditions of the Baltic Sea while offering interior accommodations usually reserved for larger vessels. Sundén, best known for refining the International Folkboat, brought a signature emphasis on seaworthiness and balanced lines to the Sunwind 27, ensuring it remained approachable for novice sailors yet rewarding for those with more experience. While the builder is no longer in operation, the vessel remains a staple of the second-hand market in Northern Europe, valued for its robust GRP construction and clever use of internal volume.

Sailing Performance & Handling
The Sunwind 27 is characterized by a high degree of stability and a "stiff" sailing profile, largely due to its significant ballast ratio and Sundén’s conservative hull form. With a fin keel and a skeg-hung rudder, the boat tracks reliably and offers a level of weatherly performance that belies its cruiser-first intentions. While it is not a dedicated racer, it performs admirably in light to moderate air, thanks to a sail plan that is manageable yet powerful enough to drive the hull efficiently.
The influence of the Folkboat lineage is evident in how the boat handles heavy weather; it tends to shoulder aside chop rather than slamming into it. Owner anecdotes often highlight its predictable behavior when reefed, noting that the helm remains light even as the wind freshens. The boat's displacement provides a secure motion at sea, which, according to historical editorial perspectives from Nordic maritime publications like Vene and Båtnytt, made it one of the more "sea-kindly" boats in the 27-foot class during its production run. It is a forgiving vessel that prioritizes safety and comfort over raw speed.
Interior Comfort & Variations
One of the Sunwind 27’s most enduring selling points is its interior layout, which was remarkably progressive for the early 1980s. Despite its modest length, the boat offers approximately 1.75 to 1.80 meters of headroom in the main cabin, a feat achieved through a slightly elevated coachroof that integrates cleanly into the deck lines. The layout typically features a classic V-berth forward, a central salon with a folding table, and a dedicated L-shaped galley located to the port side of the companionway.
The use of high-quality teak joinery—a hallmark of Finnish craftsmanship—gives the cabin a warm, substantial feel. Unlike its smaller sibling, the Sunwind 26, the 27-foot model provides a more sophisticated "big boat" layout, including a separate heads compartment located between the salon and the forward cabin. A quarter berth is often found to starboard, providing a fifth sleeping space or additional storage for long-distance cruising. While most hulls followed this standard configuration, some minor variations in engine housing and cabinetry exist depending on the year of production.
Known Issues & Buyer’s Checklist
When inspecting a Sunwind 27, prospective buyers should focus on the specific aging characteristics of GRP boats from this era. While the hulls are generally considered overbuilt by modern standards, several areas require technical scrutiny:
- Engine Maintenance: Many units were originally fitted with Yanmar or Volvo Penta diesel engines. Given their age, a thorough check of the heat exchanger, sail drive seal (if applicable), and exhaust elbow is critical. Replacement parts for older Volvo Penta models can be expensive and difficult to source.
- Deck Core Integrity: Like many boats of this vintage, the Sunwind 27 uses a sandwich construction for the deck. Buyers should use a plastic hammer or moisture meter to check for soft spots, particularly around stanchion bases and chainplates, which can indicate water ingress into the balsa core.
- Keel-to-Hull Joint: Inspect the keel bolts and the "smile" at the leading edge of the keel-to-hull joint. While the Sunwind is robust, decades of hard grounding or standard gasket wear can lead to seepage or structural stress in the bilge area.
- Rudder Bearings: The skeg-hung rudder configuration is reliable, but play in the bushings can develop over time. Check for lateral movement in the rudder stock while the boat is hauled out.
Community & Resources
The Sunwind 27 enjoys a dedicated following, particularly in Sweden and Finland. The most prominent resource for technical data and owner support is the Sunwindklubben (The Sunwind Club), a regional association that archives original brochures and maintenance tips. While much of their documentation is in Swedish, it remains the definitive source for hull numbers and historical technical specifications.
The Verdict
The Sunwind 27 is an exceptional entry-level cruiser for those who value build quality and traditional design over modern "caravan" styling. It remains a sturdy, reliable platform for coastal exploration and small-family voyaging.
Pros:
- Exceptional Headroom: Better vertical clearance than many of its contemporaries in the sub-30-foot category.
- Proven Pedigree: Designed by Tord Sundén, ensuring excellent balance and seaworthiness.
- Build Quality: Finnish construction standards provide a durable hull and high-quality interior woodwork.
Cons:
- Age-Related Maintenance: Buyers must be prepared to update standing rigging and potentially repower aging diesel engines.
- Narrow Beam: Compared to modern wide-stern designs, the cockpit can feel cramped with more than four adults aboard.
- Market Location: Most well-maintained examples are located in Northern Europe, which may complicate acquisition for North American buyers.
