Powerboats fight air to move while sailing boats use it

A2V is a new generation of transportation vessels using aerodynamics to improve energy efficiency.

During the last two years, the A2V team of naval architects and CFD specialists developed
a revolutionary shape able to safely transfer ships weight from water to air.

The required propulsive power depends mostly on the weight carried by the water. Reducing this weight is the key to greater efficiency.


From drag to support : the A2V revolution
The faster they go, the lighter they become on the water, the better their efficiency

Twice the speed, half the fuel !

We took the simple concept of aerodynamic support, went deep into its physical understanding through
an innovative research program, and found the way to make it safe, stable, simple and suitable for commercial use.

Thanks to the aerodynamic support, above a critical speed, the faster A2V vessels go the less fuel they use.
This critical speed depends on the application but the fuel economies with respect to conventional boats are very significant starting at 25 knots.

Changing the rules

The operational speed of today’s small workboats is strongly limited by the exponential growth of their fuel consumption with speed.
Oversized engines allow small speed improvements at the cost of much higher fuel consumptions and reduced payload,
leading to an economically and environmentally unsustainable cost per passenger.


Before : Higher operational speed meant higher cost per passenger.

A2V : Higher operational speed means lower cost per passenger
