Design Brief & Intent
The Contest 35 was engineered for cruisers who demanded absolute structural integrity and offshore capability without sacrificing liveability. In the early 1980s, the market was filled with lightweight, performance-oriented racer-cruisers built to satisfy the International Offshore Rule. Conyplex chose a different path, emphasizing displacement, safety, and comfort. Compared to Swedish counterparts like Hallberg-Rassy and Najad, the Contest 35 carved out a reputation for carrying slightly more beam and a higher freeboard. This design choice provided a remarkably spacious interior and solved the cramped headroom issues common in 35-foot boats of that era.
The cabin interior showcases classic Dutch craftsmanship, featuring extensive high-quality teak joinery and robust marine-grade plywood bulkheads bonded directly to the hull. With a headroom of two meters throughout the main salon, the interior feels open and airy. The layout includes a proper U-shaped galley to starboard, a dedicated navigation station to port, and comfortable settee berths flanking a central dining table.
Variations & Configurations
While later evolutions like the Contest 35S shifted toward a masthead sloop configuration and modified swim steps, the original 1981–1983 production run featured a distinct 7/8 fractional rig. This fractional setup, utilizing a tapered Seldén mast and a relatively long boom, was designed to keep the mainsail as the primary driver, making shorthanded sail handling easier under a smaller, non-overlapping headsail.
Beneath the waterline, the standard configuration is a deep, high-aspect fin keel drawing 1.90 meters, paired with a robust skeg-hung rudder. Some shoal-draft variations were produced for shallow European estuaries, though they sacrificed a degree of upwind pointing ability. In terms of interior layout, the boat is arranged as a two-cabin yacht. Unlike many aft-cabin boats of this length that suffer from restricted access, the Contest 35 features a generous passage on the port side leading to a master aft cabin equipped with an expansive double berth. The forward V-berth serves as the guest cabin, with the head compartment logically situated adjacent to the saloon.
Sailing Performance & Handling
On the water, the Contest 35 behaves like a true heavy-displacement voyager. With a displacement of 15,212 pounds and a displacement-to-length ratio of 273.89, it is designed to smooth out rough seas, maintaining momentum through heavy waves where lighter boats tend to hobby-horse. A ballast-to-displacement ratio of 45.65 percent is exceptionally high for a production yacht, indicating that the boat is incredibly stiff. It stands up well to its canvas and delays the need to reef until wind speeds climb into the upper teens.
The sail-area-to-displacement ratio of 16.94 suggests a balanced, moderate sail plan. While the boat is not a light-wind racer and requires a gentle breeze to fully wake up, it performs admirably on a reach and behaves predictably on all points of sail. Its motion comfort ratio of 28.92 translates to a gentle, slow roll-and-pitch cycle, minimizing crew fatigue during multi-day passages. With a capsize screening ratio of 1.88, the hull shape easily meets the classic safety threshold of less than 2.0, certifying its design as safe for transoceanic passages. The skeg-hung rudder provides reassuring tracking stability, allowing the helmsman or autopilot to maintain a course with minimal effort.
Market Snapshot & Economics
Decades after its production ended, the Contest 35 remains a sought-after model on the European brokerage market, particularly in the Netherlands, Germany, and Scandinavia. It commands a pricing premium compared to mass-production French and American yachts of the same vintage, owing to the enduring reputation of Conyplex build quality.
Prospective buyers should approach the purchase with a clear understanding of vintage refit economics. While the hull and deck are structurally robust, many of these vessels are still powered by their original three-cylinder, 36-horsepower Volvo Penta MD17C diesel engines. If the engine has not yet been replaced, budgeting for a modern repower is a sensible precaution 5. Furthermore, many original owners opted for teak decks, which were typically screwed into the sub-deck. Replacing or removing an aging, leaking teak deck can easily equal a significant portion of the boat's overall market value.
Known Issues & Triage
The physical vulnerabilities of the Contest 35 are common to high-quality builds of the early 1980s. The primary area of concern is the teak deck. Because these decks were laid with mechanical fasteners, a failure in the individual black caulking seams or wood bungs allows water to penetrate the screw holes. Over time, this moisture can migrate into the end-grain balsa or plywood deck core, leading to delamination and rot. Any serious buyer should insist on a thorough moisture-meter inspection of the deck.
Another critical maintenance area is the rudder and skeg assembly. Play can develop in the lower skeg bushing, resulting in a distinct clunking sensation at the helm. Triage requires hauling the boat to inspect the bronze or composite sleeve bearings for wear, which typically demands custom machining to resolve. Additionally, the stainless steel water and fuel tanks, while highly durable, are glassed into the structure or fitted tightly under the cabin sole, making inspection and eventual replacement a labor-intensive endeavor.
Modernization & Upgrades
Modern owners are actively upgrading the Contest 35 to enhance its self-sufficiency for blue-water cruising. Replacing the heavy, complex Volvo Penta MD17C engine with a modern, lightweight diesel engine—such as a Yanmar or Beta Marine unit—not only increases reliability but also frees up weight and improves fuel efficiency 5.
The original electrical systems, designed around basic 12-volt DC requirements and simple shore power chargers, are prime candidates for overhaul. The spacious compartments beneath the cabin berths make ideal locations for upgrading to lithium-iron-phosphate battery banks. Coupled with modern solar arrays mounted on a custom stern arch and high-output alternators, these upgrades allow the Contest 35 to operate comfortably off-grid. Rigging modernization is also common; owners frequently replace the original standing rigging and upgrade to modern genoa furling systems to simplify short-handed sailing.
The Verdict
The Contest 35 is an exceptional choice for traditional cruisers seeking a seaworthy, stoutly built yacht capable of safe passage-making in any weather. It trades outright speed for safety, structural integrity, and exceptional liveaboard comfort.
- Extremely robust, hand-laid fiberglass construction with a durable hull-to-deck joint.
- High motion comfort and excellent stability in heavy weather due to a high ballast ratio.
- Generous two-meter headroom and high-volume interior finished in fine teak joinery.
- Safe, deep cockpit and a reliable skeg-hung rudder for offshore peace of mind.
- Highly functional layout featuring a large, accessible aft cabin.
- Sedate sailing performance in light winds, requiring a substantial breeze to perform well.
- High risk of deck core moisture damage if original teak decks have not been serviced or replaced.
- High cost of replacing original, aging Volvo Penta engines.
- Deep standard draft limits access to shallow coastal cruising areas and canals.
