Azimuth thruster for ships : Z-drive (twin counter-rotating propellers)
COUNTER ROTATED
VETH PROPULSION
Two propellers are mounted either side of the tail, each turning in opposite directions. The second propeller eliminates the rotation in the water caused by the first propeller. This improves the vessels performance up to even 15% compared to a single propeller! As the power is divided over two propellers, it is possible to put more power on smaller propeller diameters.
