Design Brief & Intent
The core mission of the Contest 34 was to deliver a bulletproof, seaworthy cruiser capable of tackling the notorious chops of the North Sea while providing a secure and comfortable home afloat. In an era when competitors were shifting toward lighter, high-volume production, Conyplex doubled down on structural integrity. The interior finish showcases this philosophy, featuring meticulously handcrafted joinery in either rich teak or warm mahogany. With an impressive headroom of nearly two meters in the saloon, the layout feels remarkably grand and secure, utilizing heavy handrails, deep companionway steps, and robust cabinetry with positive-latching drawers. The galley and navigation station are properly sized for use at sea, reflecting a design brief that assumed the boat would be sailed in genuine offshore conditions. This emphasis on traditional offshore comfort distinguished the model from its lighter French and American contemporaries, aligning it more closely with the premium standards of Swedish-built yachts.
Variations & Configurations
The Contest 34 was offered in two primary configurations built on the same seaworthy, round-bilged hull: the traditional aft cockpit (often referred to simply as the standard layout) and the center cockpit version. An unusual and highly praised design choice on the aft-cockpit version is the inclusion of an under-deck passage that runs aft from the saloon, leading to a private aft cabin. This configuration provides two separate single berths (or a cozy double) and a dedicated washbasin in the stern, giving children or guests a distinct "private realm" without requiring a separate cockpit entrance.
The vessel is equipped with a standard deep-draft lead fin keel drawing 1.75 meters (approximately 5.7 feet). The use of lead rather than cheaper cast iron represents a premium manufacturing choice, lowering the center of gravity while minimizing water resistance. Control is maintained via a highly robust, fully skeg-hung rudder, a configuration that offers exceptional protection against impact and debris. Propulsion on almost all hulls came in the form of a reliable shaft drive rather than a sail drive, ensuring reduced long-term maintenance in saltwater environments.
Sailing Performance & Handling
Under sail, the Contest 34 is a quintessential heavy-displacement cruiser. With a substantial displacement of 16,315 pounds and a waterline length of 27.58 feet, she possesses a heavy Displacement-to-Length ratio of 347.18. Combined with a conservative Sail Area-to-Displacement ratio of 12.04, the boat is decidedly underpowered in light breezes. In under ten knots of wind, she requires patience or a massive, overlapping genoa to keep her moving.
However, when the wind rises, the Contest 34 truly shines. Boasting a massive ballast-to-displacement ratio of 43.24%, she is incredibly stiff and stands up to her canvas far longer than modern light-displacement cruisers. The boat’s physical behavior in a seaway is exceptionally comfortable. With a high Comfort Ratio of 34.39 and a Capsize Screening Ratio of 1.76, she provides a soft, predictable motion that minimizes crew fatigue. At the helm, she tracks with absolute authority, showing no tendency to break away or round up when hard-pressed, thanks to the tracking assistance of the deep skeg and well-balanced underbody.
Known Issues & Triage
While the solid-fiberglass hull laminate is incredibly durable and highly resistant to major structural failures, age-related triage is a reality on any vessel of this vintage.
- Deck Core Ingress: While the hull is a solid laminate, the decks feature a balsa or foam sandwich construction for stiffness and insulation. On models fitted with the optional factory teak decks, screw holes and worn caulking can allow moisture to penetrate the core. Prospective buyers should utilize a moisture meter and look for soft spots, particularly around chainplates, stanchion bases, and the mast step.
- Original Powertrains: Many hulls were originally delivered with the three-cylinder Volvo Penta MD17C (35/36 horsepower). Because these engines were raw-water (single-circuit) cooled, decades of exposure to salt water can cause internal clogging and corrosion. Spare parts for these older powerplants are becoming scarce and disproportionately expensive.
- Osmotic Blistering: Though Conyplex utilized high-quality resins, some hulls from this specific era are prone to superficial osmotic blistering. A haul-out inspection is highly recommended to check for gelcoat blisters and verify if a previous owner has applied an epoxy barrier coat.
- Steering Play: The bushings and bearings on the skeg-hung rudder can wear down over time, resulting in a knocking sensation or play at the wheel.
Modernization & Upgrades
Modern owners have successfully adapted the Contest 34 to modern cruising expectations through targeted retrofits:
- Engine Repowering: Replacing the original Volvo Penta with a modern, freshwater-cooled diesel engine (such as a Yanmar 3YM30 or Beta Marine 30) is the most impactful upgrade an owner can make. It reduces overall weight, improves fuel economy, eliminates raw-water cooling anxieties, and adds significant value on the brokerage market.
- Rig Modification: The original IOR sail plan relied on a massive genoa (often exceeding 450 square feet) and a small mainsail. Short-handed crews frequently modernize the sail plan by retrofitting a shorter, high-aspect roller-furling jib combined with a modern, fully battened mainsail. This dramatically reduces the physical effort required to tack the boat while maintaining good performance in moderate breezes.
- Teak Deck Elimination: To resolve moisture ingress issues permanently, many owners choose to strip away the old teak decks, repair any compromised balsa core, and finish the deck with a low-maintenance, high-durability marine paint or synthetic composite decking like Flexiteek.
The Verdict
The Contest 34 is a classic, robustly built cruiser that punches far above its weight in terms of seaworthiness, safety, and interior comfort. For sailors seeking an affordable entry-level cruiser or a budget-friendly offshore passage maker, it represents an outstanding value. While it requires patience in light air and will demand upkeep on aging systems, the yacht’s sheer build quality and "big boat" feel make it a reliable partner for serious coastal or bluewater voyaging.
Pros
- Exceptional structural integrity with a solid-glass hull built to Lloyd's specifications.
- Superb motion comfort and tracking in heavy weather and open seas.
- Clever aft-cabin layout with an interior walkthrough, unusual for a 34-foot vessel.
- High-quality interior woodwork and impressive head clearance.
- Extremely stiff and stable due to a high lead ballast ratio.
Cons
- Sluggish performance in light winds due to a heavy displacement-to-length ratio.
- Original raw-water-cooled engines are nearing the end of their service life and are expensive to repair.
- Risk of deck core rot on models with aging, screw-fastened teak decks.
- Handling a massive overlapping genoa can be physically demanding for short-handed crews.
