The various steps of the project have allowed to develop revolutionary concepts that are the core of the idea E3: a sturdy yet extremely slim and streamlined propeller, as well as easy to install and set-up. These fundamental characteristics improve the coefficient of penetration in water, largely reducing drag when sailing while exalting thrust when under power.

E3 has under taken long and enduring tests in laboratory, in basin and in sea; these have confirmed high mechanical strength, exceptional corrosion resistance, drag and thrust capabilities.
