The Kraken 40 serves as the foundational design in the Kraken Yachts "Ocean Voyager" range, conceptualized to bring the brand’s uncompromising blue-water philosophy to a more manageable, short-handed scale. Developed by founder Dick Beaumont in collaboration with Dibley Marine, the yacht was engineered to provide the same safety parameters as its larger siblings—the Kraken 50, 58, and 66—within a hull length of approximately 40 feet (12.3 meters). While the Kraken 50 eventually became the most prolific entry point for the brand in active production, the Kraken 40 design remains a significant blueprint for the company’s "Safety First" ethos, characterized by a heavy displacement hull, a protected center cockpit, and a dedicated focus on long-range autonomy.

Sailing Performance & Handling
The Kraken 40 is defined by its "Zero Keel" technology, a hallmark of the Kraken Yachts philosophy. Unlike most modern production yachts that utilize bolt-on keels, the Kraken 40 design features a keel that is an integral part of the hull molding, with lead ballast encapsulated within the GRP structure. This construction eliminates the risk of keel loss due to structural failure or grounding. On the water, this translates to a high righting moment and a very stable, predictable motion in a seaway.
Handling is further stabilized by an integral skeg-hung rudder, which provides significantly more protection than the spade rudders found on performance-oriented cruisers. While the high displacement and substantial wetted surface area mean the Kraken 40 is not a light-air racer, its hull form—featuring a fine entry and a long run aft—is optimized for maintaining consistent average speeds over long distances. Technical discussions from the designer, Kevin Dibley, suggest a vessel that tracks exceptionally well, reducing the load on the autopilot during extended offshore passages.
Interior Comfort & Variations
The interior of the Kraken 40 is designed around the concept of a "living saloon," providing a panoramic view of the horizon even when seated below deck. This raised coachroof design is a direct descendant of the larger Kraken models, aimed at reducing the "basement" feel common in traditional monohulls. The standard configuration focuses on a luxurious two-cabin layout, optimized for a couple cruising with occasional guests, rather than maximizing berth counts for charter.
Materials typically include high-grade hardwoods such as teak or cherry, with a focus on robust handholds and ergonomic security for moving through the cabin while healed. The galley is traditionally positioned in a longitudinal arrangement to provide bracing points for the cook. While the Kraken 40 is the smallest in the family, it shares the same heavy-duty systems installation as the Kraken 50, including oversized tankage and accessible machinery spaces. Because the Kraken 40 was often customized to order or presented as a semi-custom project, interior finishes can vary significantly between individual commissions.
Known Issues & Buyer’s Checklist
As a niche, high-end blue-water vessel, the Kraken 40 does not suffer from the mass-production fatigue seen in high-volume brands, but buyers should focus on the following specialized areas:
- Seal Integrity and Glazing: The signature raised coachroof features large windows. Prospective owners should inspect the seals and the integrity of the toughened glass for any signs of crazing or leakage, as these are critical for offshore safety.
- Encapsulated Ballast Inspection: While the Zero Keel is a safety feature, it is important to check the hull's exterior for any signs of osmotic blistering or impact damage that could allow water to penetrate the laminate surrounding the encapsulated lead.
- System Complexity: Kraken yachts are known for being "fully loaded" from the factory. A buyer’s checklist must include a rigorous sea trial of all secondary systems—watermakers, generators, and extensive navigational suites—as these are integrated deeply into the yacht’s wiring.
- Production Origin: Given Kraken's history of shifting production between Hong Kong, Turkey, and Poland, buyers should verify the specific build location and the yard responsible for the hull to ensure documentation for VAT and CE certification is in order.
Community & Resources
Owners of Kraken yachts are supported by a dedicated internal network facilitated by the builder. The Kraken "Ocean Voyager" community is relatively small and elite, often connecting through the manufacturer’s own organized rallies and events. For technical support, the primary resource remains the Kraken Yachts technical team and the archives of Dibley Marine, which holds the original naval architecture data for the 40-foot hull.
The Verdict
The Kraken 40 is a purpose-built tank of a sailboat, designed for the sailor who prioritizes survival and comfort over regatta trophies. It is a rare find on the brokerage market, often overshadowed by its larger sibling, the Kraken 50.
Pros:
- Exceptional Safety: The Zero Keel and skeg-hung rudder offer peace of mind that few modern yachts can match.
- Blue Water Ready: Usually comes equipped with heavy-duty gear that would be optional on other boats.
- Visibility: The deck saloon configuration provides excellent light and a sense of space.
Cons:
- Weight: High displacement makes it sluggish in light winds (under 10 knots).
- Availability: Very few units were produced compared to the Kraken 50, making them difficult to source.
- Maneuverability: The long keel and high windage make docking in tight marinas a challenge without a bow thruster.
