Contest 31 Information, Review, Specs

Sailing Performance & Handling

The Contest 31 is characterized by its heavy displacement and high ballast-to-displacement ratio, which translates to a stiff, predictable motion in a seaway. Unlike the lighter, flatter-bottomed designs of the same era, the 31 features a deep V-shaped entry and a substantial skeg-protected rudder. This configuration ensures exceptional tracking, even when running before a swell, though it does result in a larger turning circle in tight marinas.

Under sail, the boat feels remarkably secure. While it may lack the light-air agility of a dedicated racer, it excels as the wind increases. Technical data from Dick Zaal Yacht Design indicates that the hull was optimized for stability rather than outright speed, making it a preferred choice for solo sailors or small families who value comfort over VMG (Velocity Made Good). In heavy weather, the boat remains balanced, requiring minimal helm correction once the sails are properly reefed. Owners often note that the boat "starts to wake up" in 15 knots of breeze, maintaining its momentum through chop where lighter boats might stall.

Interior Comfort & Variations

The interior of the Contest 31 is a testament to the "Dutch approach" mentioned in the builder’s history, featuring high-quality mahogany joinery and a functional, sea-going layout. The standard configuration includes a forward V-berth, a central salon with settees that double as sea berths, and a compact galley and navigation station flanking the companionway. The headroom is generous for a 31-foot boat of this vintage, often exceeding 6 feet in the main cabin.

There are two primary variations of this hull: the original Contest 31 and the Contest 31 HT (Half Ton). The HT version was a evolution designed to meet the Half Ton rating rules of the time, featuring a modified coachroof and deck layout to improve crew efficiency during racing. Despite these racing aspirations, the HT retained the high-quality interior finish of the standard cruiser. While the structural hull remains largely the same, the HT’s rigging and deck hardware are often more robust to accommodate the higher loads of competitive sailing.

Known Issues & Buyer’s Checklist

Prospective buyers should focus on several age-related areas typical of 1970s GRP construction. While Contest yachts are known for their thick laminates, they are not immune to the passage of time.

1. Osmosis: Early Contest models utilized resins that are susceptible to osmotic blistering. A hull survey is essential to check for moisture levels and previous repair history.
2. Chainplate Leakage: The chainplates on the 31 pass through the deck and are bolted to structural bulkheads. Over time, the sealant can fail, leading to moisture ingress that can rot the wooden bulkheads. This is a critical structural area that requires careful inspection.
3. Rudder Bearings: The skeg-hung rudder is a safety feature, but the bushings and bearings can wear down, leading to "play" or vibration in the helm.
4. Engine Replacement: Many original 31s were fitted with Volvo Penta MD series engines. While reliable, these units are now reaching the end of their service life, and sourcing parts can be difficult. A repowered vessel with a modern Yanmar or Beta Marine engine adds significant value.
5. Window Seals: The aluminum-framed windows are prone to leaking if the original rubber gaskets have perished, which can damage the mahogany interior panels.

Community & Resources

Owners of the Contest 31 benefit from a highly active and organized community. The Contest Yachts Owners Association serves as a primary hub for technical drawings, historical data, and advice on restoration. Because Contest has maintained its reputation as a premium builder, the 31 enjoys better parts availability and community support than many "orphan" brands of the same age.

The Verdict

The Contest 31 is a "mini-tank" of the sailing world—a boat built for those who prioritize safety and longevity over modern gadgets or racing speed. It is an ideal entry-level bluewater cruiser for a couple or a sturdy coastal hopper for a family.

Pros:

• Exceptional build quality and joinery that holds up well over decades.
• Highly seaworthy hull design that provides a sense of security in heavy weather.
• Strong resale value and a dedicated owner community.
• Generous interior volume and headroom for its length.

Cons:

• Slow performance in light winds due to high displacement.
• Original engines and systems are likely to require expensive updates.
• Large turning circle makes it less maneuverable in crowded harbors.
