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

A2V is a new generation of transportation vessels using aerodynamics to improve energy efficiency.
During two intensive years, A2V’s 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.

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 economy with respect to conventional boats is very significant above 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 incremental speed improvements at the cost of much higher fuel consumptions and reduced payload, leading to an economically and environmentally unsustainable cost per passenger.

On a conventional monohull or multihull, the fuel consumption per passenger at 50 knots depends directly on the size of the vessel. The larger the vessel, the smaller the fuel consumption per passenger when the boat is fully loaded.


This explains why so far, high speed has remained restricted to routes presenting passenger flow large enough to fully load large vessels.

A2V technology changes the rules with a fuel consumption at 50 knots independent on vessel size, about 9 liters per passenger per 100km, from 10 to 100 passengers, from 12 to 30 meters. As a comparison, present state of the art crewboats typically burn more than 30 litres per 100km per passenger and travel below 40 knots.

Fuel efficiency at high speed is no longer the exclusive domain of large ships. The A2V technology opens high speed transportation to many new applications, routes and brings flexibility to shipowners business models.
