Willing 31 Information, Review, Specs

Sailing Performance & Handling

The Willing 31 reflects Linge’s philosophy of combining aesthetic grace with functional speed. Though it was designed during the height of the International Offshore Rule (IOR) era and measured as a "Half-Tonner," Linge prioritized seaworthiness over extreme rule-cheating. With a displacement of approximately 3,500 kg and a ballast of 1,300 kg (roughly a 37% ballast ratio), the boat is notably stiff and stable in heavy air. Its hull features the characteristic IOR "tumblehome" and a relatively deep fin keel, which, when combined with the skeg-hung rudder, provides excellent tracking and a predictable feel at the helm.

Performance varies significantly based on the rig configuration. The "standard" masthead rig provides a sail area-to-displacement ratio that makes the boat surprisingly lively in light to moderate winds. However, a specific variant known as the Willing 31 LR (Lav Rigg or "Low Rig") was produced with a shorter mast to accommodate specific Scandinavian bridge clearances. According to technical evaluations found on Willing.no, the standard rig version is considered "significantly overrigged" by some traditional standards, requiring early reefing to maintain optimal heel angles, whereas the LR version is more forgiving but less competitive in light air. Under sail, the boat is known for its ability to punch through North Sea chop with minimal slamming, a testament to its deep forefoot and Linge’s experience with offshore designs.

Interior Comfort & Variations

For a 31-foot yacht designed in the 1970s, the Willing 31 offers an internal volume that was considered revolutionary at the time. The high freeboard, while occasionally criticized for its aesthetic impact, allows for a generous 1.85 meters (6'1") of headroom in the main salon. The layout is traditional yet highly optimized, typically featuring a V-berth forward, a central salon with an L-shaped settee to port, and a straight settee to starboard.

A unique feature of Linge's interior design is the potential for up to nine berths through the use of "pilot berths" (sleeping spaces tucked behind and above the salon settees) and a convertible dinette. While nine adults would find the space cramped, it highlights the boat's focus on the family cruising market. Most interiors were finished in high-quality teak, which has aged well in many preserved examples. The galley is typically L-shaped and situated at the base of the companionway for ventilation. Variations in the interior are rare, as most were built to a standardized production specification, though some "owner-finished" kits exist with varying levels of joinery quality.

Popular Mentions & Media

The Willing 31 enjoys an iconic status in Scandinavia, often described by SEILmagasinet as a design that helped define the Norwegian "boating dream" of the late 70s. It is frequently featured in Norwegian sailing literature as the boat that proved a domestic yard could produce a yacht capable of crossing the Atlantic. Jan Herman Linge's daughter, Eiril Linge, continues to sail a family-owned Willing 31, a fact that reinforces the model's enduring legacy within the designer's own family.

Known Issues & Buyer’s Checklist

Prospective buyers of a Willing 31 should focus on several era-specific technical concerns that have surfaced over decades of North Sea use.

• Iron Keel Maintenance: Unlike many Swedish contemporaries that used lead, the Willing 31 was typically fitted with a cast iron keel. Rusting and "weeping" at the keel-to-hull joint are common. Owners often need to grind the keel back to bare metal and apply an epoxy barrier coat to prevent ongoing oxidation.
• Deck Delamination: The deck is a GRP sandwich construction, often using balsa or foam core. Older units frequently develop soft spots around high-load areas like the chainplates, stanchion bases, and the mast step. High-signal reports from owner groups suggest checking for moisture ingress where deck hardware has not been re-bedded.
• Original Engine Reliability: Many units still carry the original Volvo Penta MD7A diesel engine. While these are "iron lungs" known for longevity, parts are becoming increasingly scarce. The saildrive diaphragm (the rubber seal between the engine and the hull) is a critical 7-year maintenance item that is often overlooked in older boats.
• Rudder and Skeg Play: The skeg-hung rudder is robust, but the lower bearing and the attachment points of the skeg itself can develop play. Vibration at high speeds or under power is a primary indicator of worn rudder bushings.

Community & Resources

The boat is supported by a dedicated group of enthusiasts, primarily based in Norway. The Norsk Willing Klubb (Norwegian Willing Club) has historically served as a repository for technical drawings, historical brochures, and trim guides. While many of the club's active technical discussions have moved to broader Scandinavian forums like Seilmagasinet's community pages, the historical documentation maintained by the Linge estate remains the primary source for technical verification.

The Verdict

The Willing 31 is a robust, seaworthy cruiser that offers a blend of 1970s IOR-inspired performance and practical family accommodations. It remains an excellent entry-level offshore yacht for those who appreciate classic Scandinavian design.

Pros

• Outstanding headroom (1.85m) for a vessel of this length.
• Strong pedigree from Jan Herman Linge ensures balanced handling and aesthetic appeal.
• Stiff and seaworthy, capable of handling coastal offshore passages with confidence.
• High-quality teak joinery in well-maintained examples.

Cons

• Cast iron keel requires more diligent maintenance than lead equivalents.
• The "Low Rig" (LR) variant can feel underpowered in light air conditions.
• High freeboard creates significant windage when maneuvering in tight marinas.
• Original Volvo Penta engines are reaching the end of their service life and may require repowering.
