Nicholson 31 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Nicholson 31 is defined by its substantial displacement and high ballast ratio, which contribute to a stiff and predictable motion in a seaway. With a displacement-to-length ratio that firmly categorizes it as a heavy-displacement cruiser, the boat lacks the "twitchiness" of modern light-displacement hulls, making it an ideal platform for solo sailors or small crews facing heavy weather. The long keel ensures exceptional tracking, allowing the vessel to hold its course with minimal helm input, even when running before a swell.

As noted in editorial analysis by Yachting Monthly, the 31 is not a "greyhound" in light airs but comes alive when the breeze exceeds 12 knots. Its sail-area-to-displacement ratio is conservative, reflecting a design priority for safety and comfort over raw speed. The transom-hung rudder is remarkably robust, providing a tactile feel that is often lost in modern balanced spade rudders. Owners frequently report that while the boat may not win harbor-to-harbor sprints, its ability to maintain a high average speed over several days in varied conditions is where the Raymond Wall design truly excels.

Interior Comfort & Variations

The interior of the Nicholson 31 was a significant departure from the narrow, "pipe-cot" style layouts of earlier British cruisers. By increasing the beam and optimizing the hull's flare, Camper & Nicholsons created a cabin that feels considerably larger than its 31-foot LOA suggests. The layout is traditional: a forward V-berth, a heads compartment spanning the width of the boat, and a main saloon with a folding table and two settee berths (one of which can often be converted into a double).

The joinery is typical of the Gosport yard's high standards, featuring extensive use of teak and high-quality veneers. The galley is generally located to port of the companionway, with a dedicated chart table to starboard—a feature often sacrificed in modern boats of this size. One of the most praised aspects of the interior is the headroom, which exceeds six feet in the main cabin, a rarity for 1970s cruisers of this length. While there were no major structural variations in the hull, some later models featured slight refinements in the cockpit drainage and engine ventilation systems.

Popular Mentions & Media

The Nicholson 31 has earned a reputation as a "cult classic" among the long-distance cruising community. Its durability was famously demonstrated when several examples completed circumnavigations with minimal modifications. The model's reliability is a frequent topic in blue-water cruising literature, often cited as a premier choice for sailors on a budget who refuse to compromise on hull integrity. The design’s pedigree is further bolstered by the company's historical success in the America's Cup and offshore racing, lending the 31 an air of "quiet competence" that has made it a favorite subject for classic boat journals.

Known Issues & Buyer’s Checklist

Prospective buyers should focus on several specific areas that are common to yachts of this vintage and construction type:

• Engine Replacement: Many Nicholson 31s were originally fitted with the Bukh DV20 or DV24 diesel engines. While these are exceptionally reliable "marine-built" units, parts are becoming more expensive. Prospective buyers should check if the vessel has been repowered with a modern Yanmar or Beta Marine unit, as this significantly increases the boat's value and reliability.
• Osmosis: Like many GRP boats from the 1970s, the Nicholson 31 is susceptible to osmotic blistering. While the hulls are thick and rarely suffer structural failure from osmosis, a moisture meter test and visual inspection of the gelcoat are essential.
• Deck Core: The deck is a sandwich construction. Areas around stanchion bases, cleats, and the mast step should be inspected for "soft spots" which indicate water ingress into the core material—a common but labor-intensive repair.
• Rigging and Chainplates: Given the boat's age, the original stainless steel chainplates should be carefully inspected for crevice corrosion, especially where they pass through the deck.

Community & Resources

The Nicholson 31 Association serves as the primary technical repository and community hub for the model. This organization maintains an extensive archive of original drawings, technical manuals, and owner-contributed maintenance guides. The association is highly active, organizing rallies and providing a platform for owners to share specific solutions for common problems like rudder bush replacement or window resealing.

The Verdict

The Nicholson 31 is a quintessential "sailor’s sailboat," designed for those who value seaworthiness and build quality over contemporary styling and light-air speed. It remains one of the most capable offshore cruisers in the 30-foot range.

Pros:

• Exceptional heavy-weather stability and tracking.
• High-quality Camper & Nicholsons build standards.
• Genuine blue-water capability in a compact, manageable size.
• Strong class association and historical value.

Cons:

• Sluggish performance in light winds (under 10 knots).
• Difficult to maneuver in tight marinas due to the long keel and prop walk.
• Maintenance costs associated with 40+ year-old systems (original engines/wiring).
