Gib'sea 312 Information, Review, Specs

The Gib'Sea 312 began its production run in 1988, emerging from the Gib'Sea/Gibert Marine shipyard, which would eventually be acquired by the French builder Dufour Yachts. The design was penned by Rob Humphreys, a naval architect known for creating balanced and capable sailing yachts. While specific design philosophies for the 312 are not extensively detailed, Humphreys' work generally aims for a harmonious blend of sailing performance and interior volume.

The builder, Dufour Yachts, established by Michel Dufour in 1964, was an early adopter and master of fiberglass construction. From its inception, Dufour focused on producing high-quality, ready-to-sail boats using this revolutionary material, emphasizing robust construction with solid fiberglass hulls and meticulously crafted fiberglass decks. The Gib'Sea 312, built during a period of expanding manufacturing capabilities for the company, reflects this commitment to durable and consistent production quality. Many Gib'Sea 312 models were specifically built to cater to the European charter trade, indicating a design geared towards durability, ease of handling, and comfortable accommodations for multiple users. There is mention of a "Plus" version of the Gib'Sea 312, suggesting minor variations may have existed during its production, though core specifications remained consistent.

Sailing Performance and Handling

The Gib'Sea 312 is characterized by a fin keel and spade rudder, a configuration generally indicative of good maneuverability and pointing ability. With a calculated Sail Area to Displacement (SA/D) ratio of approximately 16.78, the Gib'Sea 312 can be described as a moderate performer. This ratio suggests a boat that will perform adequately in a variety of wind conditions, likely offering decent speed in light to moderate breezes without being overly sensitive or demanding in heavier air.

The Ballast to Displacement ratio, estimated at around 33% (based on a common reported ratio for a variant and the total displacement), indicates a reasonably stable vessel, though perhaps not exceptionally stiff in very strong winds. However, for a boat of its intended purpose, this provides a good balance between stability and overall weight. The Displacement to Length (D/L) ratio of approximately 206 places the Gib'Sea 312 firmly in the category of a moderate displacement cruiser. This suggests a boat that offers a comfortable motion in a seaway, rather than being a lightweight, hyper-performance design. Owners have generally described the Gib'Sea 312 as a "good sailing boat" that is forgiving, even for less experienced sailors, implying stable and predictable handling characteristics.

Accommodations and Layout

Despite its modest length overall of just over 31 feet, the Gib'Sea 312 is noted for its surprisingly spacious interior. The layout typically features two cabins, providing either four fixed berths with the possibility of additional berths in the saloon, or double cabins both fore and aft. This arrangement makes it well-suited for families or small groups, especially given its historical use in the charter industry.

The interior includes a dedicated saloon area, a head (bathroom) with shower facilities, and a galley. While the exact maximum headroom is not consistently reported across all sources, some models feature generous headroom, with up to 210 cm (approximately 6 feet 11 inches) in the aft bunk and the bathroom, which would contribute significantly to the sense of space and comfort below deck. The interior finish is often described as classic and warm, suggesting the use of traditional marine materials, possibly including wood trim, contributing to a welcoming ambiance. Storage is generally adequate for cruising needs, and ventilation is typically achieved through deck hatches and portlights.

Owner's Perspectives

Owners of the Gib'Sea 312 frequently praise its robust construction, often remarking on its solid build quality, particularly for a production cruiser of its era. Its sailing characteristics are generally viewed positively, with many appreciating its forgiving nature and good handling, even for those still honing their skills. The boat's suitability for cruising, offering a comfortable and spacious interior for its size, is a recurring theme among owners.

While generally well-regarded, some owners have noted specific maintenance points that may arise with age. For example, one owner mentioned issues with smelly seawater from the galley sink's foot pump, suggesting that attention to plumbing systems might be a common area for refurbishment on older models. Additionally, some owners have found a lack of comprehensive original user manuals, which can necessitate relying on online forums and owner communities for information and support. Despite these minor points, the Gib'Sea 312 maintains a reputation as a well-built and capable cruising yacht among its owners.
