Design Brief & Intent
The Alubat Ovni 365 was designed as an uncompromising blue-water cruiser and high-latitude expedition platform. Alubat’s target audience consisted of long-distance cruisers, high-latitude explorers, and shallow-water coastal sailors who valued extreme durability, structural isolation, and shoal-draft capabilities. The defining characteristic of the Ovni range is its "integral centerboard" design, which means the heavy ballast is placed low in the bottom of the hull rather than in the centerboard itself, allowing the unweighted board to retract completely inside the hull. This distinguishes the 365 from fiberglass competitors of the era and from more traditional steel or deep-draft GRP blue-water yachts.
The interior of the Ovni 365 departs from the "workboat" exterior aesthetic. Alubat utilized a warm, semi-custom approach, traditionally appointing the yacht in light oak veneers or American cherry (with vertical or horizontal grain), delivering a bright, traditional, and well-insulated living space. Because the hulls are welded aluminum rather than molded fiberglass, the shipyard was able to easily customize minor joinery details and structural bulkheads to meet individual owners’ specifications.
Variations & Configurations
The Ovni 365 was configured predominantly in two-cabin or three-cabin layouts, with the two-cabin version being highly favored among long-distance cruising couples. The two-cabin configuration features a spacious double V-berth forward, a large salon, a starboard-side head with a dedicated wet-locker and shower, and an expansive aft double cabin to port. The starboard-quarter in this version remains a deep, dedicated technical storage locker accessible from both the cockpit and the interior—an invaluable feature for blue-water voyaging. The three-cabin option exchanges this storage locker for a second aft double cabin and reduces the head area.
The sail plan is configured as a robust cutter rig. A tall, masthead sloop configuration is standard, but almost all offshore-oriented hulls utilize a removable inner forestay (baby-stay) to fly a dedicated staysail or storm jib, breaking down the sail plan into more manageable proportions for heavy weather. Draft varies dramatically depending on the status of the centerboard: with the board fully lowered, the boat draws 2.35 meters (approx. 7.7 feet), providing a deep profile for windward tracking, while retracting the centerboard yields a shoal draft of just 0.77 meters (2.5 feet).
Sailing Performance & Handling
At the helm, the Ovni 365 handles with a predictable, reassuringly heavy motion. Because the ballast (approximately 2,800 kg or 6,173 lbs) is distributed along the flat bottom of the hull rather than concentrated in a deep bulb, the boat’s overall displacement of around 8,800 kg (19,400 lbs) results in a moderate displacement-to-length ratio of 201.8. This keeps the boat tracking well in a seaway, though it does not possess the rapid acceleration of lighter, modern GRP hulls. The comfort ratio of 27.93 indicates a smooth, non-fatiguing motion in offshore swells.
With a sail area-to-displacement ratio hovering around 17.0, the cutter-rigged 365 is sufficiently powered but requires a decent breeze to truly come alive. In light winds under 10 knots, the wetted surface of the wide, flat-bottomed hull presents noticeable drag, and windward performance is modest. However, once the breeze fills in, the Marc Lombard-designed hull shines. The hard chines and wider stern provide excellent form stability when heeled, allowing the boat to lock in and track beautifully. Downwind and on a reach, the lifting keel can be partially raised to reduce drag, allowing the 365 to surf stably on ocean swells without the "tripping" sensation common in fixed-keel designs.
Market Snapshot & Economics
The Alubat Ovni 365 occupies a highly specialized, premium niche on the brokerage market. Unlike high-volume production GRP cruisers that experience rapid depreciation, the Ovni 365 retains its value exceptionally well, commanding a significant premium over fiberglass vessels of similar length and age. Due to the labor-intensive welding, cutting, and isolation processes involved in aluminum construction, fewer hulls were produced, making them relatively scarce outside of European (specifically French and British) waters.
Prospective buyers must recognize that buying into the Ovni ecosystem is an exercise in structural economics. The hull itself is virtually indestructible and impervious to osmosis. However, any major refit work—such as replacing structural plating, installing new thru-hull fittings, or correcting electrical faults—requires specialized aluminum-welding expertise and can carry high labor rates. Consequently, boats with well-documented maintenance histories and active galvanic isolation systems command top-tier pricing, whereas neglected hulls can represent substantial financial liabilities despite the perceived "bulletproof" nature of the material.
Known Issues & Triage
The most critical technical risk for any Alubat Ovni 365 is galvanic corrosion (electrolysis). Aluminum requires meticulous electrical isolation; the boat's 12V and 220V electrical systems must be completely two-wire (bipolar), meaning the hull must never be used as a ground. Any stray current, or the introduction of incompatible metals (such as dropping a copper coin into the bilge or using copper-based antifouling paint), can cause localized pitting in the aluminum plating. Triage requires a thorough out-of-water survey using a digital potential meter to verify hull-to-water isolation, checking the condition of the sacrificial zinc or magnesium anodes, and verifying that a galvanic isolator or isolation transformer is installed and functioning on the shore power circuit.
The lifting keel mechanism also requires routine inspection and triage. The centerboard is raised and lowered via a hydraulic pump or manual winch system. The pivot pin, lifting pennants (cables), and the Delrin/nylon guide bushes wear over time, especially if the boat is frequently operated in sandy or silty environments where abrasive grit can enter the centerboard trunk. Over time, this wear can lead to excessive play, causing the keel to clank loudly inside the trunk when sailing at certain angles or when at anchor. Dropping the keel and rudder to inspect and replace the corroded pivot pins, delaminated hydraulic seals, and worn bushes is a complex, labor-intensive yard task.
Modernization & Upgrades
Many veteran owners are proactively modernizing the Ovni 365 to suit off-grid, self-sufficient cruising. A primary focus is the transition to Lithium Iron Phosphate (LiFePO4) battery banks. Because the weight of the batteries is less critical than their capacity on a blue-water boat, owners are utilizing the space in the deep technical locker or under the salon settees to install high-capacity lithium banks, often paired with extensive solar arrays mounted on custom aluminum stern gantries (arches).
Due to the critical need for electrical isolation, modernizing owners frequently replace old brass or bronze thru-hull fittings with welded aluminum standpipes or specialized composite valves (such as TruDesign or PVC-based seacocks) to eliminate any galvanic coupling with the hull. Furthermore, replacing aged direct-drive prop shafts with modern feathering propellers (like the Max-Prop) is a highly recommended drivetrain upgrade, which reduces drag when sailing and improves astern thrust—a welcome modification given the boat's dual-rudder configuration and lack of prop wash over the rudders.
The Verdict
The Alubat Ovni 365 is an elite, purposeful cruiser designed for sailors who value ultimate structural integrity and the freedom of unlimited coastal exploration over raw racing speed. While it demands diligent electrical monitoring and offers modest light-wind performance, its ability to beach upright, safely navigate reef-strewn shallows, and weather severe offshore conditions makes it a premier choice for global cruising.
