Company History & Philosophy: A French Legacy of Aluminium Innovation

The story of Ovni sailboats begins on the Atlantic coast of France, in the renowned yachting hub of Les Sables-d'Olonne. It was here, in 1973, that the Alubat shipyard was founded with a singular, innovative vision: to build only aluminum sailboats, at a time when fiberglass was rapidly dominating the market. This commitment to aluminum as a primary construction material set Alubat apart from the outset.

The prototype of their first successful range, the Ovni 25, emerged in 1974. Initially, these were fixed-keel boats. However, a pivotal moment arrived in 1978 with the Ovni 28, which introduced the lifting keel, a signature feature that would define the brand's identity and future success. This innovation underscored Alubat's design philosophy: to create vessels that offer unparalleled freedom of navigation, allowing access to shallow waters and enabling safe beaching.

Over the decades, Alubat, and by extension the Ovni series, has navigated the ebbs and flows of the marine industry. After facing challenges around the 2008 financial crisis, a group of dedicated businessmen and loyal Alubat owners stepped in to rescue the shipyard in 2016, ensuring the preservation of its unique production, technology, and philosophy. More recently, in 2023, a team of employees, including Managing Director Luc Jurien, took over the helm, signifying a continued commitment to the brand's legacy and future. Alubat continues to operate from Les Sables-d'Olonne, employing around 47 people and having built over 1600 aluminum boats since its inception.

Design Evolution & Key Models: From Practicality to Refined Expedition

The design evolution of the Ovni series reflects a consistent focus on functionality, robustness, and ultimately, self-sufficiency for long-distance cruising. While not always winning beauty contests in the traditional sense, their utilitarian styling is a direct consequence of their expeditionary purpose.

What are the foundational and most popular Ovni sailboats?

The Ovni 28, with its pioneering lifting keel, laid the groundwork for the brand's distinctive approach. Subsequent models built upon this foundation, becoming synonymous with go-anywhere capability. While specific production numbers for each model can be elusive, some have garnered significant popularity and a strong following among blue water cruisers.

Notable models that have stood out include:

Ovni 365: Often lauded as the "Land Rover of the seas," the Ovni 365 is a capable, long-distance liveaboard cruiser known for its robust aluminum hull and ability to be beached.

Ovni 395: Designed by Philippe Briand, the Ovni 395 offered various interior configurations and maintained the crucial hydraulic lifting keel and rudder, allowing for exploration of shallow anchorages. Its design ratios indicate a balanced performance for effective sailing and good suitability for ocean passages.

Ovni 400: This model, designed with a fractional rig and a drop keel, offers above-average headroom and is considered suitable for ocean races by its capsize screening value.

Ovni 43: This model is a prime example of the Ovni philosophy, renowned for its robustness, seaworthiness, and blue water cruising capabilities. Built by Alubat between 1991 and 2000, the Ovni 43 features the signature hydraulic lifting keel and rudder, allowing for exceptional versatility in shallow waters (draft ranging from 0.8m to 2.5m). Its all-aluminum construction ensures durability, and it's well-regarded for its stable performance in challenging conditions. The Ovni 43 gained further prominence as the vessel, "Aventura III," used by celebrated circumnavigator Jimmy Cornell for extensive ocean voyages, solidifying its reputation as a highly capable and reliable offshore cruiser.

Ovni 430: Building on the success of the 400, the Ovni 430 features an inverted bow for increased volume and improved performance. It continues the tradition of large panoramic windows and a lifting centerboard, making it a strong contender for serious offshore exploration.

Ovni 445: Introduced around 2008 and designed by Marc Lombard, the Ovni 445 marked an evolution in the brand's larger cruisers. It maintained the core principles of 100% aluminum construction and the versatile lifting keel system (with a draft range from 1.05m to 2.90m), but aimed to offer enhanced performance and a more modern aesthetic. With a longer waterline and stiff sailing characteristics, the 445 was designed for excellent performance in light airs and superior comfort in rough seas, making it a strong contender for long-distance cruising without compromise.

Ovni 490: The latest in the Ovni range, the 490 emphasizes comfort and offshore capability with a pilothouse offering 360-degree views and a twin-engine option. It retains the 100% aluminum construction for reliability and safety.

Over time, design trends have seen collaborations with renowned naval architects such as Marc Lombard, Philippe Briand, and more recently, the Mortain & Mavrikios and CBA design agencies. These partnerships have introduced more voluminous and rounded hull shapes, particularly in newer models like the Ovni 430, while still adhering to the core principles of robust construction and shallow-draft capability.

Currently, Alubat offers several model lines, including the iconic Ovni range of lifting keel yachts. They also produce the Cigale range of fixed-keel yachts and, more recently, have ventured into aluminum sailing catamarans with the Ovnicat series.

Construction & Quality: The Unyielding Strength of Aluminium

The bedrock of the Ovni series is its unwavering commitment to aluminum construction. This choice is fundamental to their identity and offers significant advantages for the adventurous sailor.

What materials and techniques are used in Ovni construction?

Ovni hulls and decks are built entirely from aluminum plates of varying thicknesses, welded together over a frame. This multi-buckling frame construction creates an exceptionally strong and rigid structure. The hull typically uses plates of 8mm to 10mm thickness, while the deck and superstructure are often 6mm, and the cockpit tub 4mm.

Internally, Alubat pays meticulous attention to detail, ensuring the durability of their woodwork and the quality of electrical installations. The shipyard prioritizes strict separation of different metals to prevent electrolysis, a crucial consideration for aluminum boats. Hulls are insulated above the waterline with cold foam panels.

How durable are Ovni sailboats?

The durability of an Ovni is legendary. Aluminum, with its density and mechanical properties, provides both rigidity and shock absorption. Unlike fiberglass, which can suffer major gelcoat damage or cracking from impact, an aluminum hull is more likely to sustain only a scratch or a small bend, making it incredibly forgiving for unforeseen encounters with reefs or uncharted obstacles. This inherent strength is a primary reason why Ovnis are often referred to as "go-anywhere" boats. Furthermore, aluminum is not prone to osmosis, a common issue with fiberglass hulls, contributing to their long-term structural integrity.

Performance & Onboard Experience: Cruising with Confidence

Ovni sailboats are designed for serious cruising, and their performance characteristics reflect this purpose. While not typically regatta winners, they are lauded for their stability, seaworthiness, and ability to handle diverse conditions.

How do Ovni sailboats perform in offshore conditions?

Ovnis are renowned for their offshore capability and stability. The lifting keel system, a defining feature, offers a unique safety advantage in heavy weather; by raising the keel, the center of lateral resistance shifts, reducing leeway and allowing the boat to drift more safely in extreme conditions. With the keel fully down, they provide a deep draft for good upwind performance.

Their robust aluminum construction contributes significantly to their stability and overall feeling of security at sea. While some designs, like the Ovni 400, have a capsize screening formula that suggests suitability for ocean races, their primary design intent is comfortable and safe passage-making, rather than outright speed. They are generally considered to be reasonably good performers, balanced for effective sailing, though some models may prefer slightly deeper courses in lighter wind conditions.

What is the interior layout and comfort like on an Ovni?

The interiors of Ovni sailboats are designed with long-term cruising and liveaboard comfort in mind, prioritizing practicality and robust construction. While early models might have been more spartan, newer designs benefit from collaborations with interior designers, offering an expanded choice of wood varieties, layouts, and finishes. American Oak is a popular choice for interior woodwork, providing a light and modern aesthetic.

Key features and amenities often include:

Panoramic Windows: Newer models like the Ovni 430 and 370 feature large panoramic windows in the raised salon, offering excellent natural light and a strong connection with the outside environment.

Watertight Pilothouse: Larger models, such as the Ovni 490, often incorporate a pilothouse with 360-degree views and a watertight door, providing a protected helm station crucial for watches in challenging weather.

Flexible Layouts: Buyers often have choices between two or three cabins, varying head configurations, and different arrangements for the saloon, galley, and navigation station.

Spaciousness: Designs typically prioritize internal volume, providing ample storage and comfortable living areas for extended periods onboard.

The focus is on creating a functional and comfortable living space that can withstand the rigors of extended voyages.

What to Look For: Buying an Ovni

For those considering an Ovni, understanding their unique characteristics and potential considerations is key to making an informed decision.

Are there any common issues or quirks to be aware of with Ovni sailboats?

While Ovnis are celebrated for their strength, the very nature of aluminum construction necessitates specific considerations:

Electrolysis: This is the primary concern with aluminum hulls. Owners must be diligent about ensuring proper sacrificial anodes are installed and regularly checked. Any stray electrical currents can lead to significant corrosion.

Wiring and Paint Systems: Attention to high-quality wiring and appropriate paint systems is critical to prevent issues related to electrical currents and ensure long-term hull protection.

Maintenance: While robust, aluminum boats, like any vessel, require consistent maintenance. The lifting keel mechanism, while offering immense advantages, is a mechanical system that requires regular inspection and servicing.

What is the typical cost of ownership for an Ovni?

The total cost of ownership for an Ovni, like any sailboat, extends beyond the initial purchase price. While their robust construction might suggest lower repair costs for certain types of impact damage compared to fiberglass, ongoing considerations include:

Maintenance of the Lifting Keel: This system will require periodic servicing and potentially hydraulic fluid changes or component replacements.

Anode Replacement: Regular replacement of sacrificial anodes is a non-negotiable expense to combat electrolysis.

Paint System Maintenance: Ensuring the integrity of the paint system is crucial for long-term protection of the aluminum hull.

General Yacht Maintenance: This includes engine servicing, sail care, rigging inspections, and routine cleaning.

Ovnis tend to hold their value well due to their specialized nature, robust construction, and reputation for offshore capability. This can make them a sound investment for those seeking a true expedition vessel.

Summary: The Indomitable Spirit of Ovni
