The Granada 31, also widely recognized by its metric designation as the Granada 939, represents a high-water mark for Danish series production during the late 1970s and early 1980s. Emerging from the collaboration between the legendary Paul Elvstrøm and naval architect Jan Kjærulff, the vessel was conceived as a sophisticated cruiser-racer that could satisfy the stringent demands of the IOR (International Offshore Rule) era while providing the comfort expected of a family cruiser. Built with the characteristic robustness of Scandinavian yards, the Granada 31 gained a reputation for its stiff sailing characteristics and high-quality joinery, securing its place as a staple in Northern European marinas. While production primarily focused on the standard 31-foot configuration, the model is virtually identical to the 939, a naming convention used to emphasize its length in centimeters and align it with a more modern European marketing strategy.

Sailing Performance & Handling
The sailing pedigree of the Granada 31 is defined by its Elvstrøm & Kjærulff DNA, which prioritizes a balanced helm and efficient upwind performance. With a fin keel and a high-aspect spade rudder, the boat exhibits a level of responsiveness typically reserved for more aggressive racing designs of its period. The hull features a relatively narrow beam compared to modern 31-footers, which, combined with a healthy ballast-to-displacement ratio, ensures the boat remains "stiff" and stands up well to its canvas in a breeze.
Under sail, the Granada 31 is known for its ability to track cleanly through a chop, a necessity for the short, steep waves often encountered in the Baltic and North Seas. The rig is a traditional masthead sloop, which provides plenty of power for light-air performance while remaining manageable for a small crew. According to historical technical assessments from the era, the boat’s displacement is concentrated low, which contributes to a predictable motion at sea. Owners frequently report that the vessel feels "larger" than its 31 feet when navigating heavy weather, owing to its solid GRP layup and the structural integrity of its internal grid.
Interior Comfort & Variations
Inside, the Granada 31 showcases the Danish commitment to functional elegance and woodworking. The layout is a classic example of late-70s cruiser design, optimized for a family of four or five. The interior is typically finished in rich teak, which provides a warm, seaworthy ambiance that has aged better than many of its more utilitarian contemporaries.
The arrangement features a traditional V-berth in the bow, separated from the main cabin by a head and hanging locker. In the saloon, twin settees flank a central folding table, doubling as sea berths when underway. To the starboard side of the companionway, a dedicated navigation station is situated opposite a compact L-shaped galley. One of the more notable features for a boat of this size is the aft quarter berth, which provides a comfortable sleeping space for an adult and serves as excellent storage during long passages. Headroom is generous for a vessel of this vintage, hovering around 1.85 meters (6 feet) in the main cabin, which prevents the "closed-in" feeling common in other performance-oriented boats from the same era.
Known Issues & Buyer’s Checklist
Prospective buyers of a Granada 31 should approach the purchase with a focus on the boat’s mechanical and structural age. Because these vessels were often equipped with Bukh or Volvo Penta diesel engines mated to saildrives, the primary technical concern is the saildrive diaphragm. If the rubber seal has not been replaced within the last seven to ten years, it represents a critical maintenance item.
- Deck Core Integrity: Like many Scandinavian boats of this period, the Granada 31 utilizes a balsa-core sandwich construction for the decks. It is essential to check for "soft spots" around stanchion bases, chainplates, and the mast step, as moisture ingress can lead to core delamination over time.
- Osmotic Blistering: While Granada’s hulls were generally well-laminated, any GRP hull from the late 70s or early 80s should be inspected for signs of osmosis, particularly if the boat has been kept in warmer waters without an epoxy barrier coat.
- Rigging and Chainplates: Given the boat’s performance-oriented design, the standing rigging often sees significant stress. Buyers should inspect the stainless steel chainplates for signs of crevice corrosion and ensure the mast-step area remains structurally sound.
- Interior Linings: Some owners have noted that the original headliners or side-wall "carpeting" can begin to sag as the adhesive fails after four decades. While purely cosmetic, replacing these can be a labor-intensive project.
Community & Resources
The Granada 31 benefits from a dedicated following, particularly in Denmark, Germany, and Sweden. Owners often share technical knowledge and modification tips through regional sailing associations. The Dansk Sejlunion (Danish Sailing Association) remains a primary point of contact for historical handicap data and regional racing results for the Granada 31 class. Additionally, while the manufacturer is no longer in operation, the simplicity of the boat’s systems means that most parts—from winches to engine components—remain accessible through third-party marine suppliers.
The Verdict
The Granada 31 is a quintessential European cruiser-racer that offers a blend of performance and build quality that is difficult to find in the modern "entry-level" market. It is an ideal vessel for the sailor who values sailing dynamics and a traditional aesthetic over the voluminous, wide-stern layouts of contemporary production boats.
Pros:
- Excellent upwind performance and balanced handling.
- High-quality Danish interior craftsmanship with enduring teak joinery.
- Strong structural build capable of handling offshore conditions.
- Predictable and "stiff" behavior in heavy weather.
Cons:
- Narrower interior volume compared to modern 31-foot cruisers.
- Aging saildrive systems require diligent maintenance.
- Balsa-cored decks are susceptible to moisture if deck hardware is not re-bedded.
- Limited availability of model-specific replacement parts from the defunct manufacturer.
