« The Future belong to flying boats »

Established in Lorient (Morbihan), SEAir is a key player in the nautical world, using it's expertise to make boats fly thanks to foils. If the concept of foils is a hundred years old, it's use has been democratised over the past few years. At SEAir, thanks to the advance of our innovations, and their high potential prospects, we are convinced that foils are the nautical revolution of these coming years.

Our innovative concepts are developed on full-size demonstrators. Our in-depth scientific Research and Development process is combined with the chance to dream about flying boats. SEAir's expertise has been awarded several times: « Trophée Innovation » of the CCI of Morbihan en 2015, the special « Haute Technologie » prize 2016 of Fédération des industries nautiques (FIN) and has been awarded the « Green Tech Startup » label of the Ministry of Ecology, Energy and the Sea.

Adequate materials

Foils are revolutionary nautical equipment for the decades to come. SEAir adapts known tools and new materials to make foils perform better while being less fragile. The high variety of materials we use allows us to find solutions for different constraints, and the emergence of new industrial processes opens up new perspectives.

Multidirectional systems

To adapt to varying navigation conditions, foils need to be multidrectional. The interaction between man and foil implies a control unit allowing to simply and efficiently activate the appendages. The main system currently under development by SEAir is a control unit that enables mobility around four axes: vertical top/bottom, longitudinal front/back, rotation left/right, pendulum exterior/interior.

Electronics and energy

It's impossible to consider high tech equipment - and therefore proper flight - without electronics. To optimise and secure foil usage, it's necessary to first measure the equipment. From basic sensors to inertial units and actuators, SEAir connects equipments. It is also necessary to produce and stock energy, a task that SEAir has entrusted to qualified partners.

The instrumentation, measuring and modelling

To limit approximations, and optimise manufacturing the appendages of tomorrow, SEAir works on the load and the flight platform attitudinal data. Whether the data be related to the strain on the foils, the structure of the boat or the rigging, SEAir controls the implementation of strain gauges and fibre optics. But our expertise is fully realised in the analysis of the collected data.

3D printing

Thanks to our expertise, SEAir has considerably reduced the cost of some parts, even if they have complex geometry or are produced in small quantities. We combine different materials and assemble several parts into one, improving their mechanical properties. SEAir allows you to save time and money with faster prototyping. Practical applications? Test parts or prototypes, foil control units, fittings (cleats, pulley bodies, etc.), tooling (blocks, supports, complex boxing), instrumentation and measure supports, complex small parts casts, models, etc.

Research & development

The following definition of R&D perfectly defines SEAir'’s DNA: « The sum of systematic creative works aimed to increase knowledge. »

It isn’'t easy to think out of the box. Recreating what has already been done is much simpler. By how we operate at SEAir, we encourage collective competitiveness, giving our staff the keys and the freedom to think differently. SEAir'’s collaborative working environment fuels curiosity and imagination, two essential components of innovation.

SEAir explores uncharted nautical paths, paths that are well used in other sectors, with the objective of entering a new industrial era for systems, materials and processes.

SEAir works with 3D printing for fast prototyping, implements foils and measures the strain placed on them, to develop patent protected systems.

There is no R&D without qualified staff. SEAir is partnered with renowned research labs such as The French Naval Academy Research Institute (IRENAV) and Bretagne Sud University. Patents and thesis around SEAir have already been published.
