Sunwind 20 Information, Review, Specs

Sailing Performance & Handling

The Sunwind 20’s performance is defined by its high ballast ratio, which often exceeds 40% of its total displacement. This design choice, a hallmark of Tord Sundén’s philosophy, results in a remarkably stiff and forgiving sail plan. While it lacks the raw acceleration of a modern sportboat, the Sunwind 20 excels in heavy air where other 20-footers might feel overwhelmed. The boat features a fin keel and a transom-hung rudder, providing a balanced helm and respectable tracking.

Technical data indicates a displacement-to-length ratio that leans toward the "heavy cruiser" end of the spectrum for its size. This weight gives the boat a predictable motion in a seaway, reducing the "bobbing" sensation common in light-displacement 20-footers. According to archival testing notes from the Finnish boating publication Vene-lehti, the Sunwind 20 is particularly noted for its ability to maintain a steady course when close-hauled, requiring minimal correction from the helm. However, because of its relatively narrow beam and traditional hull form, it can be somewhat "wet" in a chop, as the bow tends to drive through waves rather than over them.

Interior Comfort & Variations

For a vessel of its era and size, the Sunwind 20 offers a surprisingly functional interior, though it is strictly limited by a lack of standing headroom. The layout typically features a classic four-berth configuration: a V-berth forward and two long settee berths extending aft under the cockpit seats. The "pocket cruiser" designation is earned through the inclusion of a small, often slide-out galley area and dedicated storage lockers under the cushions.

The cabinetry is usually finished in teak or mahogany veneers, reflecting the high standards of 1970s Finnish craftsmanship. While there were no major hull variations, later production models saw slight modifications to the interior liner to improve drainage and ventilation. The sibling models in the Sunwind line—most notably the larger Sunwind 26 and 27—expanded on this layout by adding standing headroom and enclosed heads, but the Sunwind 20 remains a "sitting headroom" boat designed for coastal weekend hops rather than extended living.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Sunwind 20 with the understanding that these vessels are now decades old and require specific structural scrutiny.

• Deck Core Integrity: Like many GRP boats of this vintage, the Sunwind 20 uses a sandwich construction for the deck. Buyers should check for soft spots, particularly around the mast step and the chainplates, which can indicate water ingress and delamination of the balsa or foam core.
• Rudder Bushings: The transom-hung rudder is simple to maintain, but the pintles and gudgeons often show signs of wear. Excessive play in the tiller often points to the need for new bushings or a reinforcement of the mounting points.
• Window Seals: The original aluminum-framed or rubber-gasket windows are prone to leaking. Given the age of the boat, these seals have likely perished, and evidence of water staining on the interior woodwork is a common finding.
• Keel Bolts: While the keel attachment is generally over-engineered, it is vital to inspect the internal keel bolts for corrosion, as many of these boats have spent their lives in brackish or salt water.

Community & Resources

The primary hub for technical information and historical data is the Finnish Sunwind-purjehtijat (Sunwind Sailors) community. While most official manufacturer documentation from Oy Nykra Ab is out of print, Swedish and Finnish owner associations maintain digital archives of original sail plans and rigging specifications.

The Verdict

The Sunwind 20 is an exceptional "first boat" for those who value safety and traditional aesthetics over modern speed. It is a sturdy, well-mannered cruiser that punches well above its weight class in terms of seaworthiness.

Pros:

• Exceptional Stability: High ballast ratio makes it very safe for beginners and solo sailors.
• Build Quality: Finnish construction standards from the 1970s result in a very thick, durable hull.
• Pedigree: Designed by Tord Sundén, ensuring classic lines and balanced handling.

Cons:

• Cramped Quarters: No standing headroom and limited space for a marine head.
• Weight: Heavier than modern 20-footers, making it more difficult to trailer and launch without a dedicated crane.
• Performance in Light Air: The heavy displacement can make the boat feel sluggish when winds are below 8 knots.
