From classic thrusters we have developed two systems of propulsion and maneuvering, retractable and azimuthal. Both have incorporated nozzle to increase the thrust.
The first is mounted in a box provided in the keel of the boat attached to a descending column using two telescopic hydraulic cylinders. It rotates 380 ° with a rack attached to hydraulic cylinders such as cranes. When the boat sails with the main propulsion system the azimuth thruster or propeller is retracted and the box covered. The position is controlled all time by means of encoders (angle, speed and elevation) sowing the information in the screen of a control panel fitted in the
