The lifting-keel sailboat that takes you further… without going bigger
Under 12 m. 100% aluminium.
Designed for sailing with two people or single-handed.
OVERVIEW
Compact in size broad in horizons
The OVNI 370 combines the essential features of a true blue water yacht in a compact design that is easy to handle with a small crew or when sailing solo. Built entirely in aluminium, with an centreboard and a modern hull form, it combines robustness, safety, comfort and the joy of sailing, all within a length of less than 12 metres.
Its rounded, inverted bow, panoramic coachroof and semi-thick aluminium construction give it an instantly recognisable character. But beyond its aesthetics, each of these design choices meets a specific requirement: to offer a sailing yacht capable of passage-making voyages, yet remaining easy to handle and pleasant to live on day-to-day.
Technical specifications of the Ovni 370
The OVNI 370 thus occupies a unique position. It retains the fundamentals that have made the OVNI range famous – 100% aluminium construction and a centreboard – while adopting a resolutely modern hull and architecture. This combination now gives it a unique position in the market for blue water boats with centreboards.

Why the OVNI 370?
The freedom to sail wherever you like
Sail up a river, or take shelter at the back of a cove too shallow for keelboats: that’s the advantage of a lifting-keel sailboat, here in a size that can be handled without additional crew.
Anchorages beyond the reach of keelboats
With the centreboard raised, the 370 draws just 0.92 m, compared with 3.08 m when lowered for better upwind performance. Shallow waters, estuaries and lagoons become a whole new playground for sailing.
Long-distance cruising autonomy
With 330 litres of fresh water and 450 litres of diesel, the boat offers greater independence: weeks at anchor, non-stop passages. Its carrying capacity keeps pace, with plenty of room for provisions, spare parts and equipment.
A bluewater cruiser under 12 metres
Modern hull design, welded hull, and offshore certification: the 370 is built for long passages and high latitudes. Its size remains that of a boat that can be handled by two and is easy to accommodate in a marina.

Designed to enjoy A word from the architects
A word from Mortain/Mavrikios
For Alain Mortain, of the Mortain/Mavrikios team of naval architects, every design choice contributes to the boat’s overall balance:
« To meet the requirements of Category A, we’ve moved the centre of buoyancy slightly forward, allowing the ballast to be kept in a low position and thereby slightly refining the waterline in the forward third. The rounding of the bilge in the forward third improves stability at greater wind angles and increases interior volume. »
A word from CBA
This quest for balance is also reflected in the choice of semi-thick aluminium construction. Jean-Pierre Brouns, of the CBA design office, explains:
« We have combined our expertise with the team at Mortain/Mavrikios to design a sailing yacht with semi-thick aluminium hull plating, ensuring exemplary strength that allows for cruising anywhere while optimising the structure’s footprint, and consequently, thermal bridges.. »
A modern design
Pour satisfaire aux exigences de la catégorie A, Alain Mortain a légèrement avancé le centre de carène : le lest reste bas et la flottaison s’affine dans le tiers avant. Le livet arrondi sur l’avant améliore la stabilité aux grands angles et libère du volume intérieur.
Insulation for all latitudes
Two layers of sprayed cork and a layer of Armacell foam (30 mm in total) insulate the structure above the waterline: less condensation and greater thermal stability, in cold climates as well as in the tropics.
CONFORT
An interior that’s
An interior that’s
open to the horizon
Aboard the OVNI 370, comfort extends naturally to the outside. The raised saloon, offset to starboard, forms a genuine deck lounge, wide open to the horizon thanks to the panoramic coachroof.
From the saloon, the unobstructed views allow you to navigate whilst enjoying the comfort of the interior. On the port side, the raised chart table also offers a prime vantage point for watchkeeping, planning the next stages of the voyage or working on board.
The galley, situated on the port side, features ample storage space. Every detail is designed to make life on board easier: positioned beneath the central seating opposite the companionway, the drawer-style fridge opens forward for convenient and safe access.
Smart life onboard
Near the companionway, the wet locker is naturally positioned just before the bathroom.
Forward, the separate shower provides added everyday comfort, which is particularly welcome on long passages.
Aft on the starboard side, a compartment houses the electrical equipment while retaining a flexible space that can be adapted to suit your needs and your project.
Effective temperature control
Comfort on board also depends on effective temperature control.
The OVNI 370 features double insulation combining two layers of sprayed cork and a layer of Armacell foam, giving a total thickness of 30 mm from the waterline to the deck.
This insulation minimises thermal bridges and helps reduce condensation, while providing genuine thermal inertia. The interior therefore remains a more pleasant place to be, whether in cold climates or in the tropics.
The all-round companion
With the OVNI 370, Alubat offers much more than just a 37-foot centreboarder: This a genuine, compact, comfortable and easily manoeuvrable blue water yacht, designed for sailing far and wide.
Solo or short-handed Outdoor comfort, designed for long-distance sailing
Aboard the OVNI 370, outdoor comfort is based above all on intuitive and safe sailing. Every element of the deck layout has been designed to facilitate sailing manoeuvres and make the boat particularly easy to handle, even when short-handed.
All lines centralised in the cockpit
Lines are centralised in the cockpit, directly accessible from the helm, and grouped around the two coachroof winches, which are fitted as standard. This layout simplifies operations, minimises the need to move about on deck and allows the skipper to remain fully focused on sailing.
The twin steering wheels provide excellent visibility when helming and ensure a smooth flow of movement in the cockpit. At the bow, the twin bow roller makes for easy anchoring and contributes to the boat’s offshore capabilities.
Des systèmes simples et fiables
Designed to cruise the world’s oceans, the OVNI 370 prioritises a robust, versatile design free from any unnecessary complications. Its shaft-driven propeller offers a reliable and tried-and-tested solution, whilst its centreboard, which is manually raised and lowered, can be assisted by an electric winch for added convenience.
Simple, reliable and functional choices, all serving the same aim: to make everyday sailing easier and allow the crew to enjoy the voyage to the full.

Frequently Asked Questions
Honest answers to the questions sailors ask before committing.
What is a lifting-keel sailboat?
Can the OVNI 370 be beached?
Yes, this is one of the advantages of its design: the 370 can sit safely on a suitable seabed while waiting for the tide, opening up sheltered anchorages and estuaries that are inaccessible to keelboats.
What type of sailing is the OVNI 370 designed for?
Designed for bluewater cruising with two people, whether sailing single-handed or with a small crew, from northern archipelagos to tropical lagoons. Its compact dimensions make harbour manoeuvres easier without compromising its offshore capabilities.
Does aluminium rust at sea?
No: rust only affects ferrous metals, while aluminium protects itself with a thin oxide layer. The key consideration is galvanic corrosion (contact with other metals or stray electrical currents), which can be controlled through careful electrical installation, suitable anodes and regular maintenance.
Where are the sailboats in the range built?
Can you customise your sailboat, and what are the lead times?
Each boat is built to order: layout, equipment and options are defined with our teams. Lead times depend on the order book, production capacity and the options selected.
