History and Design
The Ovni 37 emerged during a period when Alubat was cementing its reputation for specializing in lifting keel aluminium boats, a niche largely overlooked by other manufacturers since its founding in 1973. The boat's production run from 1985 to 1989 saw the continuation of Alubat's commitment to robust construction techniques, leveraging the inherent qualities of aluminium for strength and durability. Notably, the Ovni 37 shares its hull design with the earlier Ovni 35, distinguished by the addition of a stern scoop extension, which likely enhanced its waterline and potentially improved performance or stern access. Alubat's design ethos during this era focused on creating strong, aesthetically pleasing boats that met the demanding requirements of blue-water cruising, often incorporating distinctive hard chine hulls that contribute to stability and interior volume.
Sailing Performance and Handling
The Alubat Ovni 37 is designed for comfortable and capable cruising, a characteristic well-reflected in its specifications. With a sail area to displacement ratio (SA/D) of approximately 18.28, the Ovni 37 exhibits good potential for performance, particularly in lighter wind conditions, allowing it to move efficiently without excessive wind. Its ballast to displacement ratio (B/D) stands at a healthy 41.1%, indicating a stiff and stable vessel capable of standing up to significant wind and maintaining an even keel. This high ballast ratio, combined with its robust aluminium hull, contributes to a secure and comfortable motion offshore. The displacement to length ratio (D/L) of around 214 places the Ovni 37 in the category of a moderate displacement cruiser, balancing load-carrying capacity with reasonable performance. Anecdotal accounts from owners suggest that the older Ovni 37 models handle rough weather admirably, with one owner noting it performed as well as a Hallberg-Rassy 352 in challenging conditions. The lifting keel design, a hallmark of Alubat, provides the versatility to navigate shallow waters and even dry out on tides, expanding cruising grounds considerably.
Accommodations and Layout
The interior of the Ovni 37, while often described as functional, offers a practical layout suitable for extended cruising. With a maximum headroom of 6.23 feet, the cabin provides comfortable standing room for most individuals. The general impression among owners is that the interior is "kinda basic but good enough," emphasizing practicality over luxurious finishes. Typical configurations included a two-cabin layout, suggesting good use of space for a vessel of its size. While specific details on materials and storage can vary, Alubat's focus on customizability means that individual boats may feature unique internal arrangements and finishes. The emphasis remains on providing a durable and liveable space for offshore voyages, aligning with the boat's primary purpose as a blue-water cruiser.
Owner's Perspectives
Owners of the Alubat Ovni 37 consistently praise its solid construction and robust build, which instills confidence in challenging conditions. The boat's ability to handle rough weather well is a frequently highlighted strength, underscoring its design as a reliable offshore vessel. The lifting keel is another major advantage, opening up a world of shallow-water cruising and exploring otherwise inaccessible anchorages. While the interior is often characterized as basic, owners appreciate its functionality and suitability for extended life aboard. Maintenance discussions in owner forums suggest a dedicated community, with questions often revolving around practical aspects like electrical and plumbing plans for these enduring yachts, indicating a commitment to their long-term upkeep. The strong sense of community among Alubat owners, particularly through groups like the "Ovni Club," further attests to the satisfaction and loyalty inspired by these capable cruisers.
