The Contest 34, designed by the prolific Dick Zaal and built by the Dutch yard Conyplex (now Contest Yachts), represents a pivotal moment in the evolution of the brand. Launched in the mid-1970s as a successor to the highly successful Contest 31 and 33, the 34-footer was engineered during an era when the builder was transitioning from high-volume production to the semi-custom, premium bluewater niche they occupy today. Characterized by a robust fiberglass layup and a heavy-displacement hull, the Contest 34 was produced in two primary configurations: the "S" (Center Cockpit) and the "AC" (Aft Cockpit), both sharing the same seaworthy hull form that has since earned a reputation for reliability in the North Sea and beyond.

Sailing Performance & Handling
The Contest 34 is a quintessential heavy-displacement cruiser, designed more for "momentum and motion comfort" than high-speed light-air performance. With a displacement-to-length ratio typically exceeding 300, it possesses the physical mass required to punch through a choppy head sea without the jarring motion characteristic of modern, light-skinned production boats. According to technical archives from Dick Zaal Yacht Design, the hull features a deep V-shaped entry and a substantial keel—typically a fin keel with a skeg-hung rudder—which provides exceptional directional stability.
In terms of handling, the boat is known for its "stiff" nature, meaning it carries its sail area well into freshening breezes before requiring a reef. Owners often report that the boat feels "locked in" when reaching, though the heavy wetted surface area means it requires a significant breeze (12 knots or more) to truly wake up. The skeg-hung rudder offers a level of protection and tracking that makes the 34 a preferred choice for solo or shorthanded sailors who prioritize a predictable helm over the twitchy responsiveness of a spade rudder.
Interior Comfort & Variations
The interior of the Contest 34 is a showcase of traditional Dutch craftsmanship, utilizing high-quality teak joinery that has, in many cases, outlasted the upholstery and systems of its contemporaries. The "S" (Center Cockpit) version is particularly notable for its era, as it managed to squeeze a dedicated aft cabin into a 34-foot hull—a feat that often resulted in cramped quarters on other vessels but was handled with ergonomic care by Zaal. This version typically features a walk-through or a side-access to the aft berth, providing a level of privacy rarely found in boats of this size.
The Aft Cockpit (AC) variant, conversely, offers a more traditional layout with a larger cockpit and a more expansive main salon. Both models generally provide 6'2" to 6'3" of headroom in the main cabin, which was generous for the 1970s. The galley is typically U-shaped and positioned to port or starboard of the companionway, designed for use at sea with deep sinks and secure bracing points. While the layout is conservative by modern standards, the use of solid wood trim and the absence of interior liners (which allows for better access to the hull) distinguish the 34 as a "proper" yacht rather than a coastal cruiser.
Known Issues & Buyer’s Checklist
Prospective buyers of a Contest 34 should approach the vessel with an understanding of its age, focusing on the specific construction methods used by Conyplex in the late 1970s.
- Teak Deck Longevity: Many Contest 34s were delivered with thick teak decks screwed and glued to the sub-deck. After four decades, these decks often reach the end of their lifespan. Look for evidence of "popped" screws or thinning wood, which can lead to moisture ingress into the deck core.
- Osmotic Blistering: While Contest used high-quality resins, some hulls from this period are known to develop osmotic blisters. A thorough haul-out inspection is necessary to determine if the hull has undergone a barrier coat treatment.
- Rudder Bearings and Skeg: The skeg-hung rudder is a safety feature, but the bronze or composite bushings can wear over time, leading to play in the helm. Inspect the junction where the skeg meets the hull for any stress cracking.
- Engine Replacement: Many units were originally fitted with Volvo Penta or Bukh diesel engines. While reliable, parts for older models like the Volvo MD11C are becoming scarce. A vessel with a repowered Yanmar or Beta Marine engine carries significant added value.
Community & Resources
Owners of the 34 benefit from one of the most organized owner structures in Europe. The Contest Yachts Owners Association maintains a wealth of technical knowledge, providing access to original blueprints and historical documentation. This community is particularly active in the Netherlands and the UK, often hosting rallies and sharing DIY solutions for the common maintenance tasks associated with the Dick Zaal-era models.
The Verdict
The Contest 34 is a "small ship" in every sense of the word. It is a vessel designed for the sailor who values structural integrity and sea-kindliness over the high-volume interiors and flat-water speed of modern designs. While it requires a dedicated maintenance schedule—particularly regarding its woodwork and teak decks—it remains a premiere choice for those looking to cross oceans on a modest budget.
Pros:
- Exceptional build quality with high-grade teak joinery.
- High motion comfort and stability in heavy weather.
- Center cockpit variant offers a private aft cabin unusual for this length.
- Strong resale value and dedicated manufacturer support through the heritage department.
Cons:
- Heavy displacement results in sluggish performance in light winds.
- Maintenance-heavy teak decks are common on the secondhand market.
- The age of the vessel often necessitates significant electronic and plumbing upgrades.
