Our skills at your service

SEAir's clients are engineering consulting firms, shipyards and skippers wanting to enhance the performance of their boats by implementing foils. Our skills cover all aspects of flight: from the preliminary studies and designs to the manufacturing of foils, through the instrumentation and flight modelling.

Expertise

Allowing boats to fly thanks to an optimal integration of foils and foil systems on boats of all shapes and sizes.

Credibility

Using our extensive experience acquired by in depth R&D conducted on our demonstrators - two Moths, a Mini 747 and a motor boat.

Added value

Bringing the best performance possible to boats by manufacturing foils, implementing our control units and enhancing settings.

"Foils are decidedly the nautical revolution of these coming years."
SEAir's vision

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.

The Moth workshop

Competitions require a high level of customisation to adapt the boat for each racer. This requires an ultimate expertise, expertise we have on Moths, with a renowned skill set. Several race boats (from all over the world) have been enhanced in our workshops.

SEAir parts

V6R : The back foil

Back foil Order

On high level Moths, the back foil is a stabiliser. Depending on it's size and incidence, it helps the back of the boat take off at slow speed. During upwind sailing, it must carry 10 to 20% of the total weight, in downwind we need to reduce the lift to avoid plunging. The smaller the foil, the faster it is. Le V6R foil fits that expectation: a symmetrical Matthias Renken type profile, a straight horizontal rake (non anhedral), thin and narrow, with a maximum span.

Clamp blocks

Clamp block - cale à mords Order

To adjust foils with maximum precision and consistency, SEAir has developed giant clamp blocks. Specific to the foil profile, connected to your smartphone with a 'spirit level' application, the clamp block with give you the angle of incidence between the foil and the hull, set to zero beforehand. For Moth Mach2, Early Lift or standard (large) foils, Safran anhedral (medium), V6R / standard (large) and more. With this clamp block, the setting of your foil won't take more than two minutes.

Patented product

Moth boom

Boom Order

On Moths, the boom is the focal point of strain and performance. It's 17° curved profile allows to swing the mast back, while still being able to manoeuvre by moving under it. The allows to gain speed in most cases, the centre of buoyancy being lower and further back. This amounts of rearing the boat, allowing to lower the incidence of the foils. Ideal for lower mast heels with high pressure vangs.
