The Ovni 435 was introduced in 2004, continuing Alubat's legacy of innovative aluminum sailboat construction that began in 1973. Designed by Philippe Briand, a prominent French naval architect known for his expertise in both racing and cruising yacht design, the 435 embodies a philosophy focused on robust seakeeping and practical offshore capability. Alubat, from its shipyard in Les Sables d'Olonne, France, has consistently specialized in lifting keel aluminum boats, a niche that has earned them a reputation for rugged construction and unparalleled versatility. The Ovni 435 features the distinctive hard-chine aluminum hull characteristic of the Ovni range, a design choice that contributes to both stability and interior volume. Throughout its production, Alubat offered a high degree of customization, allowing owners significant input into their vessel's interior layout and finishes 2, 6, Builder Article.

Sailing Performance and Handling

With a length overall of just over 42 feet and a waterline of nearly 35 feet, the Ovni 435 is designed for purposeful cruising. Its sail area to displacement ratio, calculated at approximately 14.64, suggests that while capable, it is not optimized for extreme light-air performance. However, its displacement of 22,707 pounds, combined with a displacement to length ratio of around 241.9, positions it as a moderately heavy cruiser, promising a comfortable motion in a seaway rather than a light, skittish ride. The boat's ballast to displacement ratio of 34.9% indicates moderate stiffness, which is notably complemented by its high form stability, a characteristic often found in designs with hard chines.

Owners frequently praise the Ovni 435 as a "good sea boat" with "excellent seakeaping," capable of handling diverse conditions and offering a balanced helm. With a hull speed of approximately 7.9 knots, it offers efficient passage making under sail, and can motor comfortably at around 6.5 knots in calm conditions. The lifting keel, allowing for a draft ranging from a mere 2.43 feet to a deeper 8.33 feet, provides unparalleled access to shallow anchorages and the ability to dry out on tides, a key aspect of its "go anywhere" ethos.

Accommodations and Layout

The Ovni 435 offers a spacious and practical interior designed for extended periods at sea and comfortable living in port. With approximately 6.4 feet of headroom, the living spaces feel open and accommodating. While specific layouts can vary due to Alubat's emphasis on customization, a typical arrangement often includes an offset double V-berth forward, a well-appointed head, a comfortable salon, and a functional galley. Owners report having considerable input on the interior design, allowing for unique configurations and the choice of finishes such as cherry wood. The design prioritizes practicality, ensuring the interior functions well both at sea and in harbor, with ample storage for provisions and personal gear, crucial for long-distance cruising.

Owner's Perspectives

Owners of the Ovni 435 consistently laud its "bullet proof construction" and the inherent safety and security provided by its all-aluminum, hard-chine hull. The boat's robust build and comfortable motion are frequently cited strengths, making it a highly regarded vessel for serious blue-water voyaging. The versatility afforded by the lifting keel is a particular highlight, enabling access to areas otherwise inaccessible to fixed-keel yachts. The ability to customize the interior is also greatly appreciated, allowing owners to tailor the boat to their specific cruising needs and preferences. While minor issues can arise, as with any complex vessel, owners generally consider them manageable. The active "Ovni Club" community further underscores the loyalty and satisfaction of Alubat owners, who benefit from shared knowledge and experiences, reinforcing the Ovni 435's reputation as a cherished voyaging platform.
