Design and Construction
The Ovni 430 measures 12.90 metres overall, with a beam of 4.36 metres and a light displacement of 11,900 kg. She carries 3,330 kg of ballast plus a 700 kg ballasted centreboard. Her rounded, inverted bow gives her an 11.54 m waterline—nearly the full hull length—and she retains the marque’s lifting-keel, beachable philosophy while refining it considerably for this model.
This is the first Ovni with an additional chine in the bottom of the hull. The change reduces wetted surface area and, together with thicker bottom plating, marks a departure in Alubat’s construction strategy for the Ovni 430.
Alubat calls the new approach “semi thick” construction. The bottom plate is 10 mm aluminium, the rest of the hull is 8 mm, and the deck and coachroof are 6 mm. By comparison, the earlier Ovni 400 and its siblings used 8 mm alloy plate throughout.
The extra chine and a 9 cm reduction in freeboard lower the centre of gravity and give the 430 greater stability than earlier models. Alubat also widened the forward two-thirds of the hull to increase form stability. This allowed the forward coachroof to be broadened by 235 mm without sacrificing side-deck width.
Twin angled rudders sit well outboard on the new chine. They are deliberately short and have a low aspect ratio, allowing the yacht to dry out on its flat bottom. The steering has also been re-engineered for a more direct response. A rope system replaces hydraulics for lifting the centreboard, while a tunnel bow thruster takes the place of a retractable unit.
Deck finish is of a high standard, with welds ground smooth and neat paintwork. Deep bulwarks and solid metal handholds near waist height provide security around the deck, while ample cleats and a deep, capacious chain locker support practical cruising. Aft, the transom carries an arch, and the open cockpit has wide, accessible gangways and twin helm stations.
Rig and Handling
The standard rig carries a conventional 44 m² pin-head mainsail. An optional 52 m² square-top main is available, but it requires running backstays. Well-swept spreaders support the rig when gybing in light airs.
The cap shrouds lead to welded aluminium chainplates on the outside of the hull. Lower shrouds terminate beside the coachroof, leaving the side decks clear. Sail-plan options include a permanently rigged roller-reefing staysail or a set of removable flying sails. The boom sits slightly lower, and the headsails are tacked lower to add sail area without increasing air draught. Rather than leading aft to the stern arch, the mainsheet uses mirrored port and starboard systems led to the coachroof.
Under way, test sailors found the helm positive, responsive and predictable even at two knots of boat speed. In six knots of true wind, the hull consistently made just over four knots—about 70 percent of wind speed.
The 700 kg centreboard is raised using the starboard companionway electric winch, which also handles the main halyard. Roller-bearing luff cars ease reefing. On the test boat, the first two reefs used a single-line system, with separate pennants for the third reef.
Accommodation
Below, buyers can choose between a classic saloon and a new deck-saloon layout. The deck saloon has a raised dining area with views through the coachroof windows. In the classic version, a seated viewer is limited to one hull window on each side.
Both layouts share a raised navigation station with the same outlook. An offset port-side saloon keeps the route forward clear, while a large linear galley to starboard provides good stowage and worktop space.
The accommodation also includes a generous head with a separate shower and a large owner’s cabin. A technical area aft of the heads contains a single bunk on an aluminium base. This base doubles as a workbench and provides access to the electrical equipment and generator.
An optional solid aluminium doghouse protects the helm. An optional dog-house below extends sheltered visibility.
Propulsion and Equipment
Standard propulsion comes from a 50 hp Volvo Penta D2-50 with shaft drive. A hybrid system, first seen on the test boat, is also available. It combines a 28.8 kW lithium-ion phosphate bank, an 11 kW Fischer Panda diesel range extender, 900 W of solar capacity, and regeneration of 300 W while sailing at 4.5 knots.
In light airs, applying only 3.3 kW of electric propulsion more than doubled the yacht’s speed to 4.4 knots. Exceeding six knots required 22 kW, however, giving little more than an hour of electric-only range at that pace.
Three electric winches, including both primary winches, reduce the physical effort required from the crew.
Verdict
The Ovni 430 refines a proven aluminium cruising formula with smarter construction and easier handling. At the same time, it retains the shallow-draught, beachable character that defines the marque.
Pros
- The additional hull chine and semi-thick plating lower the centre of gravity and increase stability.
- With the centreboard raised, draught is 0.85 m for beaching and access to shallow water.
- The helm remains direct and predictable at very low speeds.
- The deck-saloon option greatly improves visibility when seated.
- Electric winches and the rope-operated centreboard lift reduce crew effort.
Cons
- According to the first owners, the hybrid Oceanvolt throttle lacks a conventional feel.
- The square-top rig requires running backstays, adding complexity.
- The low-aspect-ratio rudders and flat bottom prioritise drying out over high-speed balance.
