The Contest 250 C represents a significant chapter in the evolution of Dutch boatbuilding, serving as the refined successor to the original Contest 25 that launched the Conyplex yard into international prominence. Designed by Dick Zaal, who took the foundation laid by Jacques de Ridder’s 1959 design and modernized it for the 1970s market, the 250 C (often referred to interchangeably as the later-generation Contest 25) was built in Medemblik with a focus on North Sea durability. While many 25-footers of its era were designed as light-air "lake boats," the 250 C was engineered as a genuine "pocket cruiser," capable of handling the steep chops and unpredictable weather of Northern Europe. It retains the classic aesthetic of the Contest Yachts Heritage—robust fiberglass construction, a high ballast ratio, and a level of interior joinery that far exceeded the mass-produced standards of contemporary competitors.

Sailing Performance & Handling

The Contest 250 C is characterized by its "big boat" feel, a trait derived from its moderate displacement and a hull shape that prioritizes stability over raw speed. Unlike modern flat-bottomed sportboats, the 250 C features a traditional fin keel and a skeg-hung rudder, a configuration that provides exceptional directional stability. This makes the vessel particularly forgiving for single-handed sailors or those navigating in heavy weather; it tracks cleanly and resists the "twitchiness" often associated with lighter 25-footers.

The design by Dick Zaal emphasizes a high ballast-to-displacement ratio, which allows the boat to carry its sail area longer than its peers before requiring a reef. In light air, the 250 C may feel somewhat sluggish due to its wetted surface area, but it truly comes alive in 12 to 18 knots of breeze. Owners frequently report that the boat’s motion is predictable and seaworthy, lacking the violent motion found in flatter hulls. Its ability to "heave-to" effectively and its sea-kindly nature make it one of the few vessels of this size that experienced sailors trust for coastal hops across the English Channel or the North Sea.

Interior Comfort & Variations

For a vessel with a length overall of just under 25 feet, the Contest 250 C offers a remarkably functional interior that reflects the Dutch commitment to craftsmanship. The layout typically features a classic four-berth configuration: a double V-berth in the bow and two longitudinal settees in the main cabin. Unlike the original 1959 model, the 250 C benefited from an updated coachroof design that increased standing headroom, making the cabin feel significantly more voluminous.

The use of mahogany and high-quality veneers remains a hallmark of the model, providing a warmth and "ship-like" ambiance that is rare in modern entry-level cruisers. The galley is compact but seaworthy, usually positioned near the companionway for optimal ventilation and ease of use while underway. Variations of the model occasionally appear with different engine configurations; while many were fitted with the ubiquitous Volvo Penta MD series, some later units utilized Farymann or Yanmar powerplants. The transition from the original Contest 25 to the 250 C also saw improvements in the placement of the marine head, which is usually situated between the main salon and the forward cabin, often featuring a sliding door for privacy—a luxury for a boat of this footprint.

Known Issues & Buyer’s Checklist

Prospective buyers of a Contest 250 C should focus their inspections on the age-related realities of 1970s fiberglass construction. While the hulls are famously "over-built," they are not immune to the passage of time.

  • Osmotic Blistering: Like many GRP boats from this era, the 250 C can be prone to osmosis. A professional moisture meter reading of the hull below the waterline is essential, though many examples have already undergone epoxy treatments.
  • Deck Core Integrity: The decks are typically cored, and moisture ingress around stanchion bases, chainplates, or the mast step can lead to delamination. Buyers should check for "soft spots" or "springy" areas underfoot.
  • Engine Serviceability: Many original units still house the Volvo Penta MD1 or MD2. While these are robust, finding parts can be increasingly difficult. Check for heavy smoking or "milky" oil, which may indicate a failing head gasket or heat exchanger issues.
  • Window Seals: The aluminum-framed portlights are known to leak over decades as the sealant dries out. Look for water staining on the mahogany joinery directly beneath the windows.
  • Standing Rigging & Chainplates: Given the boat’s offshore capability, the rig is often pushed harder than a standard daysailer. Inspect the chainplates for signs of stress or weeping, as they are a critical failure point in heavy weather.

Community & Resources

Owners of the Contest 250 C benefit from a dedicated and highly organized community. The Contest Yachts Owners Association serves as the primary hub for technical data, archival brochures, and refit advice. This group is particularly valuable for sourcing replacement parts or finding original design drawings for the 250 C. Because the boat was widely exported, there are active owner clusters in the Netherlands, Germany, and the United Kingdom, often sharing knowledge through regional rallies and technical forums.

The Verdict

The Contest 250 C is a quintessential "sailor's boat," offering a level of security and build quality that is increasingly rare in the sub-30-foot market. It is an ideal choice for the traditionalist who values seaworthiness and craftsmanship over modern amenities or racing performance.

Pros:

  • Exceptional build quality and "big boat" sea-kindliness.
  • Predictable, stable handling due to the skeg-hung rudder and high ballast ratio.
  • Beautifully finished mahogany interior that provides a cozy, classic atmosphere.
  • Strong resale value and a dedicated community of enthusiasts.

Cons:

  • Slower performance in light winds compared to modern, lighter designs.
  • Maintenance requirements of an older GRP hull (potential for osmosis/deck leaks).
  • Limited standing headroom for sailors over six feet tall.
  • Original engines may require expensive replacement or specialized parts.
