The Ovni 445, designed by the prolific Marc Lombard Yacht Design, represents a pivotal evolution in Alubat’s storied lineage of aluminum lifting-keel cruisers. Launched as the successor to the highly successful Ovni 43, the 445 was tasked with modernizing the "go-anywhere" philosophy of the shipyard while improving aerodynamic efficiency and interior volume. Built in Les Sables d'Olonne, France, the vessel is constructed from AlMg 4.5 Mn (5083) aluminum, featuring the brand's signature hard-chine hull. Unlike many of its predecessors, the 445 benefited from Lombard’s expertise in performance hull shapes, resulting in a more powerful stern section and a refined entry. The model served as a bridge between the traditional ruggedness of the older 435/455 series and the contemporary styling of the newer Ovni 400 and 450 models.

Sailing Performance & Handling
The Ovni 445 is an "integral dériveur," meaning its centerboard retracts completely into the hull, allowing for a minimum draft of approximately 1.05 meters (3’5”). In deep-water mode with the board down, the draft extends to 3.07 meters (10’1”), providing significant lift and reducing leeway during upwind beats. While older Ovni models were often criticized for sluggish performance in light air, the 445 utilizes a more generous sail-area-to-displacement ratio, typically around 19.5, which helps it maintain momentum in moderate conditions.
Handling is characterized by the use of twin rudders, a design choice by Lombard to ensure the boat remains controllable even when heeled, despite its wide 4.29-meter beam. According to technical assessments by Alubat, the twin rudder configuration is essential for maintaining grip when the centerboard is partially raised to reduce drag off-the-wind. Owners frequently report that the 445 tracks with more precision than the older 43, though it remains a heavy-displacement cruiser (approx. 11,550 kg) that prioritizes stability and sea-kindliness over raw racing speed. The hull’s hard chines act as stabilizers when the boat is pressed, providing a predictable "lock-in" point that enhances comfort during long offshore passages.
Interior Comfort & Variations
The interior of the Ovni 445 is a departure from the dark, utilitarian cabins of 20th-century aluminum yachts. Alubat typically finished these vessels in light oak or American cherry, which, combined with the large coachroof windows, creates an airy, panoramic atmosphere. The integration of the centerboard trunk is a central design challenge in any integral cruiser; in the 445, it is cleverly disguised as a part of the saloon table assembly, ensuring it does not obstruct movement through the cabin.
The 445 was primarily offered in two or three-cabin configurations. The owner’s version features a spacious forward cabin with a dedicated head, while the three-cabin version splits the aft section to accommodate larger crews. A hallmark of the 445 is its versatility; Alubat often accommodated semi-custom requests, meaning some hulls may feature specialized workshops or "wet lockers" for heavy-weather gear. Headroom is generous throughout, typically exceeding 1.95 meters in the main saloon, making it a viable long-term liveaboard for taller sailors.
Known Issues & Buyer’s Checklist
Prospective buyers of an Ovni 445 must focus their inspection on the unique properties of aluminum and the mechanical complexity of a lifting keel.
- Galvanic Corrosion: While AlMg 4.5 Mn is highly resistant to seawater, the boat is vulnerable to stray current electrolysis. Buyers should inspect the hull for pitting, particularly near through-hull fittings and the stern. It is critical to verify the integrity of the insulating bushings on all stainless steel hardware attached to the aluminum deck.
- Centerboard Mechanism: The hoisting system—usually a hydraulic ram or a manual winch system—requires scrutiny. The pivot pin and the nylon glides that prevent the board from rattling inside the trunk are wear items. If the board "clunks" in a seaway, the bushings likely need replacement.
- Paint and Antifouling: Aluminum requires specific primers (often epoxy-based) to ensure paint adhesion. Look for bubbling or "lifting" of the paint at the waterline or around the chines, which can indicate poor surface preparation or moisture trapped during the last application.
- Tankage Integrity: The water and fuel tanks in the 445 are often integrated into the hull structure. While this adds strength and lowers the center of gravity, it makes cleaning or repairing a leak more difficult. A pressure test of the tanks is recommended during a pre-purchase survey.
Community & Resources
The Ovni 445 enjoys a dedicated following within the broader Alubat community. The Ovni Owners Association acts as the primary hub for technical exchange, providing detailed documentation on maintenance specific to aluminum hulls. Because these boats are often used for high-latitude trekking or circumnavigations, the community is a rich source of information regarding aftermarket modifications such as hard-dodgers, wind generators, and heating systems (e.g., Webasto or Eberspächer), which are common on the 445.
The Verdict
The Ovni 445 is a premier choice for the "blue-water nomad" who requires a vessel capable of both crossing oceans and tucking into tidal estuaries where fixed-keel yachts cannot follow.
Pros:
- Exceptional Versatility: The 1.05m minimum draft allows for canal cruising and "drying out" on sandy bottoms.
- Robust Construction: The aluminum hull offers immense peace of mind in areas with floating debris or ice.
- Modern Hull Form: Improved performance and tracking compared to earlier, heavier-keeled generations.
Cons:
- Maintenance Intensity: Requires vigilant monitoring of the electrical system and anodes to prevent corrosion.
- Mechanical Complexity: The lifting keel and twin rudders add more moving parts than a traditional fin-keel cruiser.
- Initial Cost: Aluminum construction is labor-intensive, keeping resale values high and initial entry prices steep.
