Ovni 31 Information, Review, Specs

The genesis of the Ovni 31 lies in Alubat's early years, with its production run from 1976 to 1980. Designed by naval architect Michel Joubert, it was the second model in Alubat's burgeoning range of offshore alloy yachts, a period when the builder began to solidify its reputation for rugged, aluminum lifting-keel vessels. Alubat, founded in 1973, distinguished itself by exclusively building boats from aluminum, a material choice that provided unparalleled strength and durability, ideal for demanding blue-water cruising. While the iconic Ovni 28, launched in 1978, is often credited with defining the hard chine characteristic of the Ovni range, the Ovni 31 also shares this robust construction ethos, designed for strength and offshore capability. This era saw Alubat focused on creating yachts that were "exceedingly strong," a core principle evident in the Ovni 31's build.

Sailing Performance and Handling

The Alubat Ovni 31 exhibits a compelling blend of performance and stability, characteristics derived from its carefully balanced design. With a Sail Area to Displacement (SA/D) ratio of approximately 21.9, the Ovni 31 is considered a high performer, suggesting good responsiveness and a respectable turn of speed, particularly in lighter wind conditions. Its Ballast to Displacement (B/D) ratio of around 0.42 indicates a high degree of stiffness and stability, allowing the boat to stand up well to a breeze and providing a comfortable motion in a seaway. The Displacement to Length (D/L) ratio of roughly 251.9 places it in the moderate-to-heavy displacement category for a vessel of its size, affirming its credentials as a solid and reliable cruiser rather than an ultralight racer. Owners and reviewers often describe the Ovni 31 as a "very high performer" that is "very stable / stiff," making it a reliable choice for extended voyages.

Accommodations and Layout

Despite its focus on rugged offshore capability, the Alubat Ovni 31 offers a comfortable and practical interior, designed for life aboard. The boat provides a maximum headroom of 6.0 feet, which is generous for a vessel of its length, contributing to a more open and livable feel below deck. The interior typically features appealing mahogany joinery and cork deckheads, creating a classic and inviting atmosphere. While specific detailed layouts can vary, Alubat's reputation for offering adaptable interior designs means owners could often tailor their boats to specific needs. The Ovni 31 is generally designed to accommodate up to six people, suggesting a layout that includes a forward V-berth, a main salon with convertible settees, and potentially a quarter berth, suitable for couples or small families embarking on extended cruises. A water capacity of 40 gallons further supports its capability for longer periods away from shore.
