The Contest 48 S Ketch is a quintessential example of the "Dutch approach" to bluewater cruising: a robust, Lloyd’s-certified vessel designed for high-latitude exploration and effortless passage-making. Developed by Conyplex in Medemblik and designed by the prolific Dick Zaal, this model evolved from the successful Contest 46, often utilizing the same foundational hull but extending the transom to a "sugar scoop" configuration that increased the waterline length and provided easier water access. Built during an era when the shipyard transitioned from serial production to semi-custom luxury, the 48 S was constructed to withstand significant offshore stress, featuring a hull-to-deck joint that is fiberglassed together rather than mechanically fastened—a hallmark of the yard's commitment to structural integrity. While earlier Contest 48s were produced in limited numbers in the late 1970s, the "S" variant of the 1980s and early 1990s represents the design's maturity, balancing a heavy displacement profile with a versatile ketch rig that appeals to shorthanded crews.

Sailing Performance & Handling
Classified technically as a "heavy cruiser," the Contest 48 S Ketch possesses a Displacement to Length (D/L) ratio typically exceeding 320, signaling a hull that prioritizes stability and load-carrying capacity over light-air agility. Owners and reviewers often describe the vessel as exceptionally "kind" in a seaway; with a Motion Comfort Ratio (MCR) in the low 40s, it resists the jerky, quick motions common in modern, lighter-displacement designs. The fin keel and skeg-mounted rudder configuration provide a middle ground between the maneuverability of a spade rudder and the tracking of a full keel, though the boat is noted for being remarkably "on rails" when the ketch rig is balanced.
The ketch sail plan is the defining characteristic of this model’s handling. By splitting the sail area across two masts, the center of effort remains lower, which reduces the heeling moment compared to a similarly sized sloop. In heavy weather, sailors can employ the "jib and jigger" configuration (headsail and mizzen), keeping the boat balanced and powered up while the mainsail is safely stowed. This versatility is frequently cited in owner reports as a primary reason for choosing the 48 S for long-distance cruising. However, the trade-off for this stability is performance in "whispery" winds, where the 48 S requires a significant breeze or the use of an asymmetrical spinnaker to maintain momentum.
Interior Comfort & Variations
The interior of the Contest 48 S is a testament to traditional Dutch joinery, dominated by hand-finished teak and a layout designed for living aboard at sea. The classic three-cabin configuration features a sprawling owner’s suite aft, made possible by the center-cockpit design. This cabin typically includes a large island berth, dedicated seating, and an en-suite head with a separate shower stall. Forward of the main saloon, the boat usually offers a V-berth in the bow and a second guest cabin with bunk berths to port, sharing a second head.
The saloon is characterized by high headroom and a "U-shaped" settee that doubles as a secure sea berth. A significant variation found in the sibling models, such as the later Contest 48CS (Centerline), moved toward more modern, open-concept aesthetics, but the 48 S retains a more compartmentalized, offshore-friendly feel with ample handrails and a dedicated, forward-facing navigation station. The galley is typically located in the passageway to the aft cabin, providing a secure "bracing" position for the cook while underway.
Known Issues & Buyer’s Checklist
While built to Lloyd's Register standards, the age and construction methods of the Contest 48 S necessitate specific inspections for prospective buyers:
- Deck Core Integrity: The decks and some sections of the topsides are balsa-cored. While Contest Yachts is known for high-quality layups, moisture ingress around improperly bedded hardware can lead to core delamination. A percussion "tap test" or moisture meter reading of the deck is essential.
- Teak Deck Wear: Many units were delivered with thick, vacuum-glued teak decks. Replacing these is a significant capital expense; buyers should check for thinning wood or "proud" screws (though later models used adhesive rather than fasteners).
- Keel-to-Hull Joint: Although the "Swan smile" is less common in this marque, the cast-iron keel is bolted to a deep GRP stump. Any evidence of weeping or rust at this joint should be investigated for potential keel bolt torque requirements or fairing issues.
- Original Engine Condition: Many 48 S models were originally fitted with Volvo Penta MD40 series engines. While reliable, parts for these aging blocks are becoming scarcer, and many owners have opted for modern repowers from Beta Marine or Yanmar.
- Rigging Age: Given the complexity of the ketch rig, the standing rigging for both masts must be inspected. Many owners of this model have added hydraulic or electric furling systems (Reckmann or Selden) which, while convenient, require specialized servicing of the motors and seals.
Community & Resources
The most prominent resource for technical documentation and owner support is the Contest Yachts Owners Club (CYOC), which maintains an active database of historical brochures, wiring diagrams, and a forum for sharing refit advice. The builder also provides support for older models through Contest Brokerage, which often maintains the original build specifications and hull records for individual vessels.
The Verdict
Pros:
- Exceptional build quality certified by Lloyd’s, offering peace of mind for ocean crossings.
- Versatile ketch rig allows for easy sail handling and balance in a wide range of conditions.
- "Motion Comfort" remains far superior to modern production cruisers of the same length.
- Massive interior volume with a true "superyacht-style" aft owner's cabin.
Cons:
- Heavy displacement results in sluggish performance in light winds (under 10 knots).
- High maintenance costs associated with a second mast and extensive teak decking.
- Balsa-cored sections require vigilant moisture monitoring to avoid expensive repairs.
- Large turning radius makes tight marina maneuvering a challenge without a bow thruster.
