The OVNI 31 is a popular sailing boat designed and built by the French shipyard Alubat. It is part of the OVNI (Objet Volant Non Identifié) range, which translates to Unidentified Flying Object, referring to the boat's ability to sail in various conditions and explore remote areas.

The OVNI 31 is a medium-sized cruising sailboat known for its robust construction and excellent seaworthiness. It has a length overall (LOA) of around 9.5 meters (31 feet) and a beam of approximately 3.3 meters (10.8 feet). The boat's hull is made of aluminum, which provides durability and resistance to corrosion.

One of the key features of the OVNI 31 is its lifting keel, allowing it to navigate in shallow waters and even beach itself if needed. This feature makes it suitable for exploring coastal areas, rivers, and other shallow waterways. The lifting keel also enhances the boat's stability and performance while sailing.

The OVNI 31 has a spacious and well-designed interior layout, offering comfortable accommodation for a small crew or a couple. It typically includes a forward cabin, a saloon with a dining area, a galley, a navigation station, and a head compartment. The boat's interior is known for its practicality and storage space.

In terms of performance, the OVNI 31 is designed to be easily handled by a small crew. It has a balanced sail plan with a fractional rig, allowing for efficient sailing in various wind conditions. The boat's design also incorporates a center cockpit, providing good visibility and protection for the crew.

Overall, the OVNI 31 is a versatile and reliable sailing boat suitable for coastal cruising and exploring remote areas. Its robust construction, lifting keel, and comfortable interior make it a popular choice among sailors looking for a capable and seaworthy vessel.
