Gecco 39 Information, Review, Specs

Sailing Performance & Handling

The Gecco 39 was engineered for the challenging conditions of the Baltic and North Seas, resulting in a hull that is both stiff and predictable. According to technical specifications maintained by the designer at Sass Design, the yacht features a moderate-displacement hull with a fin keel and a spade rudder. This configuration, paired with a relatively high ballast ratio (often exceeding 40%), ensures that the boat remains upright and maintains momentum in a chop.

Under sail, the Gecco 39 is noted for its "groove-seeking" ability; once the sails are trimmed, the boat tracks exceptionally well, requiring minimal input from the helm. The flush deck provides an unobstructed platform for crew work during maneuvers, though the lack of a raised coachroof means the cockpit can feel somewhat exposed in heavy following seas. With a Sail Area-to-Displacement (SA/Disp) ratio that leans toward the performance-cruising end of the spectrum, the boat excels in medium to heavy airs. Owners frequently report that while the boat requires a breeze to truly "wake up," it remains manageable and safe long after lighter boats have been forced to reef.

Interior Comfort & Variations

Despite its low-profile flush deck, the Gecco 39 offers surprising volume below deck, achieved through a deep hull section and clever utilization of the nearly 11-foot beam. The interior is typically finished in traditional Scandinavian style, featuring extensive use of satin-varnished mahogany and high-quality joinery. The standard layout includes a forward V-berth, a central salon with twin settees that double as sea berths, and a dedicated navigation station and galley flanking the companionway.

A significant point for prospective buyers is that many Gecco 39s were delivered as "semi-finished" kits. This means that while the hull and deck were factory-built, the interior fit-out was often completed by the original owners or local shipwrights. Consequently, the quality of the cabinetry and the specific layout of the aft quarters—some featuring a double quarter-berth and others a single—can vary significantly from one hull to the next. The sibling model, the Gecco 33, followed a similar design philosophy but on a smaller scale, lacking the standing headroom and the expansive nav station found in the 39.

Known Issues & Buyer’s Checklist

When inspecting a Gecco 39, the primary focus should be on the integrity of the deck and the vintage of the mechanical systems.

• Deck Core Integrity: While the flush deck is aesthetically pleasing, many units were fitted with teak-overlay decks. Over decades, the thousands of screws used to secure the teak can allow moisture to penetrate the balsa or foam core. Potential buyers should use a moisture meter and listen for "thumping" sounds that indicate delamination.
• Keel Attachment: The Gecco 39 utilizes a deep fin keel. Inspect the keel bolts and the surrounding fiberglass grid for any signs of "smile" cracks at the leading edge or compression at the trailing edge, which could indicate a previous grounding.
• Engine Service Life: Many original models were equipped with Volvo Penta MD series engines. While reliable, parts for these older units are becoming increasingly scarce. Check the heat exchanger and exhaust elbow for corrosion.
• Rudder Bearings: The spade rudder is subject to significant leverage. Check for excessive "play" or wobble in the rudder post, which often indicates that the bearings or bushings require replacement—a common maintenance task for yachts of this age.

Community & Resources

While there is no dedicated international class association for the Gecco 39, owners are primarily active in Northern European maritime circles. Technical data and original design blueprints are often sourced through the Sass Design archives, as Heinz-Jürgen Sass remains a recognized figure in Swedish naval architecture. General technical discussions regarding the boat's construction are frequently found within the Swedish "Sailguide" community, where the model is highly regarded as a "Klassiker."

The Verdict

The Gecco 39 is a sophisticated, "sailor’s sailboat" that offers a level of build quality and aesthetic grace rarely found in modern production yachts. It is best suited for experienced coastal cruisers or offshore sailors who value sea-kindliness and classic lines over maximum interior cabin count.

Pros:

• Excellent heavy-weather performance and tracking.
• High-quality Scandinavian mahogany craftsmanship.
• Striking flush-deck aesthetics that stand out in any marina.
• Robust, hand-laid hull construction.

Cons:

• Variable interior quality due to some units being owner-finished.
• Flush deck results in less natural light and ventilation compared to modern trunk-cabin designs.
• Teak decks on older models are often reaching the end of their functional life.
• Relatively narrow beam limits the size of the aft sleeping quarters.
