The Fifty 33, produced by the Kirié shipyard in Les Sables d’Olonne, represents a quintessential era of French motorsailers from the late 1970s and early 1980s. Designed by the prolific naval architecture duo Michel Joubert and Bernard Nivelt, the vessel was engineered to bridge the gap between a power cruiser and a traditional sailing yacht. Unlike the later "Feeling" range which leaned toward performance-oriented cruising, the Fifty series prioritized stability, interior volume, and reliable motoring capabilities for the rugged Atlantic coast. It sits as the mid-sized anchor of the Fifty range, following the smaller Fifty 27 and preceding the flagship Fifty 40.

Sailing Performance & Handling
The Fifty 33 is characterized by a "50/50" design philosophy, meaning it is intended to split its utility equally between its sails and its engine. With a hull form designed by Joubert-Nivelt, the boat features a relatively heavy displacement and a full-bodied midsection that provides significant initial stability. While it lacks the pointing ability of a dedicated racing yacht, its performance on a reach is remarkably steady. According to historical design notes from the Joubert-Nivelt Design Office, their hulls from this era focused on seaworthiness and predictable behavior in the choppy waters of the Bay of Biscay.
Under sail, the Fifty 33 requires a stiff breeze to come alive; in light air, the wetted surface area of the heavy hull often necessitates motor-sailing. The boat’s tracking is excellent due to a longish fin keel and a protected rudder, making it a forgiving choice for long-distance cruising. Handling is typically managed via a dual-station steering system—a traditional wheel in the cockpit and a secondary helm station inside the protected deckhouse, allowing for comfortable navigation during inclement weather.
Interior Comfort & Variations
The interior of the Fifty 33 was revolutionary for its time, utilizing a "deck saloon" or raised-coachroof configuration that flooded the living space with natural light. The primary layout features a large U-shaped settee to port with a galley to starboard, positioned so that the cook and guests can maintain a view of the horizon through the large deckhouse windows. This emphasis on visibility and "inside-outside" living was a precursor to modern catamaran design philosophies.
Kirié offered the Fifty 33 with a few layout variations, primarily focused on the aft section. While most models feature a V-berth forward and a large head, some variants included a dedicated aft cabin tucked under the cockpit sole, while others utilized that space for an expansive storage locker or "garage" for cruising gear. The use of warm teak joinery and high-quality upholstery was a hallmark of the shipyard during this period, contributing to a sense of durability and traditional maritime comfort.
Known Issues & Buyer’s Checklist
Prospective owners of a Fifty 33 should focus their inspections on the specific age-related vulnerabilities common to 1980s Kirié builds.
- Deckhouse Window Seals: The expansive acrylic windows are a defining feature but are prone to crazing and seal failure. Owners often report leaks that, if left unaddressed, can damage the interior woodwork and the sandwich core of the side decks.
- Engine Integration: Because the Fifty 33 relies heavily on its motor (often originally equipped with Perkins or Volvo Penta units), the engine mounts and exhaust system undergo more stress than on a typical sailing yacht. Verify the condition of the shaft seal and the alignment of the drivetrain.
- Osmotic Blistering: Like many polyester boats of the late 70s, the Fifty 33 can be susceptible to osmosis. A thorough hull survey is recommended to check for moisture levels in the laminate, particularly around the turn of the bilge.
- Steering Linkage: The dual-station steering system introduces complexity. The cables or hydraulic lines connecting the interior helm to the cockpit pedestal should be inspected for tension and wear to ensure there is no "play" in the rudder response.
Community & Resources
The Fifty 33 benefits from a dedicated following in Europe, particularly within the French cruising community. Owners often coordinate through the "Association des Propriétaires de Kirié et Feeling" (APKF), which serves as a technical repository for the Fifty and Feeling ranges. While many resources are in French, the group remains a vital source for sourcing original parts and sharing restoration advice for the Fifty line.
The Verdict
The Fifty 33 is a robust, sensible cruiser for those who prioritize comfort and protection from the elements over raw speed.
Pros:
- Excellent visibility and natural light in the main cabin.
- Dual-station steering offers year-round cruising versatility.
- Solid Joubert-Nivelt hull design provides a safe, sea-kindly motion.
Cons:
- Sluggish performance in light winds (less than 10-12 knots).
- High maintenance requirements for the large deckhouse windows.
- The heavy displacement makes it less nimble in tight marina maneuvering.
