The Gib’Sea 352 represents a pivotal era for Gibert Marine, marking the point where the French shipyard sought to blend its reputation for robust charter vessels with the refined performance characteristics of internationally renowned naval architecture. Launched in the late 1980s and produced into the early 1990s, the 352 was a departure from the purely utilitarian cruisers of the early decade. Designed by Robert Humphreys—an architect more frequently associated with high-performance racing yachts and the Oyster range—the 352 brought a level of sophistication to the mid-sized cruising market that was often missing from its contemporary rivals. It was built during the peak of Gibert Marine’s independence before its eventual absorption into the Dufour family, and it remains one of the most respected hulls to emerge from the Marans yard.

Sailing Performance & Handling
The influence of Robert Humphreys is immediately apparent in the Gib’Sea 352’s hull form. Unlike some of its flatter-bottomed French contemporaries, the 352 features a relatively deep, modern hull with a fine entry that allows it to handle choppy coastal waters with significantly less slamming than typical 1980s charter boats. While it carries a generous beam for its length to satisfy interior volume requirements, the underwater profile is balanced, providing a stable platform that remains predictable even when pressed.
Under sail, the boat is known for being surprisingly stiff. With a displacement of approximately 4,500kg to 5,000kg (depending on the ballast configuration), it possesses enough mass to carry momentum through a tack, yet it remains responsive to the helm thanks to its large spade rudder. In an editorial retrospective by Yachting Monthly, the model was noted for its respectable performance on all points of sail, particularly its ability to hold a line upwind. The standard masthead sloop rig is simple to manage, and while it is not a dedicated club racer, the 352’s sail area-to-displacement ratio suggests a boat that is more than capable of double-digit speeds in a stiff breeze without feeling tender.
Interior Comfort & Variations
The Gib’Sea 352 was ahead of its time regarding interior modularity, offered in both a two-cabin "Owner" version and a three-cabin "Club" version. The three-cabin layout was particularly successful in the Mediterranean charter trade, as it managed to fit two double aft cabins and a forward V-berth into a 34-foot-6-inch hull without making the salon feel cramped. This was achieved through a linear galley located along the port side of the main cabin—a design choice that maximizes floor space but can be challenging for the cook when the boat is heeling on a starboard tack.
The two-cabin version, conversely, provides a massive aft cabin and a significantly larger heads compartment, making it a favorite for long-term cruising couples. Headroom is generous throughout, hovering around 1.9 meters (6'3") in the main salon. The use of light oak or teak veneers, combined with numerous deck hatches and the signature long coachroof windows, creates a bright, airy atmosphere. The 352’s hull was also used as the foundation for the later Gib’Sea 362; the primary difference between the two is the 362’s integrated sugar-scoop transom, which extended the overall length and improved water access for swimmers.
Known Issues & Buyer’s Checklist
Prospective buyers of a Gib’Sea 352 should approach the vessel with a focus on its history, as many of these boats spent their early years in rigorous charter service.
- Window Sealing: The long, curved acrylic windows on the coachroof are a hallmark of the 352's design, but they are notorious for developing leaks over time. These windows are bolted and bonded; the thermal expansion of the acrylic often causes the sealant to fail, necessitating a complete remove-and-reset procedure.
- Structural Grid Bonding: As with many French production boats of this era, it is essential to inspect the bonding of the internal fiberglass grid (the matrix that supports the mast step and keel bolts) to the hull. Signs of cracking or separation near the keel floors can indicate a history of groundings.
- Rudder Bearing Wear: The spade rudder is efficient but puts significant stress on the upper and lower bearings. Any "knocking" felt through the wheel or visible play at the rudder stock should be addressed, as these bearings are a standard wear item on the 352.
- Osmosis: While Gibert Marine used high-quality resins, boats from the late 80s are at an age where osmotic blistering can occur. A moisture meter check of the hull below the waterline is a standard requirement for this model.
- Engine Maintenance: Most 352s were fitted with the Volvo Penta 2003 or Yanmar 3GM series. While reliable, the Volvo 2003 is known for spline wear on the gearbox coupling; buyers should verify that the "spline fix" or a replacement coupling has been implemented.
Community & Resources
Owners of the Gib’Sea 352 benefit from a strong, albeit decentralized, network of enthusiasts across Europe. The Gib’Sea Owners Association (historically based in the UK) serves as a primary hub for technical manuals and historical brochures. Because of the 352's shared DNA with the 312 and 372 models, technical advice regarding parts and modifications is often interchangeable across the "2-series" range. Furthermore, because Dufour still supports many of the legacy hulls through their wider dealer network, certain specialized hardware components can still be sourced.
The Verdict
The Gib’Sea 352 is a "sleeper" in the used boat market. It offers the pedigree of a Robert Humphreys design at a price point often lower than contemporary Beneteaus or Jeanneaus of the same size. It is a robust, sea-kindly cruiser that punches above its weight in heavy weather while providing a layout that remains competitive with modern designs.
Pros:
- Excellent hull design by Robert Humphreys provides superior handling compared to many 80s cruisers.
- The three-cabin layout is remarkably efficient for a sub-35-foot vessel.
- Bright, ventilated interior with ample headroom.
- Solid construction capable of extended coastal or cross-channel voyaging.
Cons:
- Linear galley layout in the three-cabin version can be impractical at sea.
- Coachroof windows are prone to leaking and require meticulous maintenance.
- Many examples have a history of heavy use in Mediterranean charter fleets.
