Counter Rotating Propellers (CRP)
When there is little space or a low vessel draught, Current Motion can deliver thrusters with counter rotating propellers (also called contra rotating propellers).

Maximum Propeller Efficiency
Current Motion thrusters are designed to accommodate a large propeller diameter, maximising efficiency at low vessel speeds. Thanks to the electric drive and carefully selected gear ratios, the thruster can also run at maximum load with a smaller propeller, since the drive line is engineered to keep the propeller operating within its most efficient range, regardless of diameter.
Low-Noise Operation
To minimise sound levels, Current Motion uses a pulling propeller (tractor) configuration, which creates an optimal wake field ahead of the propeller. This means the propeller can be designed purely for maximum efficiency, without compromises to the blade design to compensate for a disturbed wake field.
Product features
Increased thrust and efficiency
Counter-rotating propellers generate higher thrust levels than single-propeller designs, leading to improved propulsion efficiency and better fuel economy for the same power input.
Reduced propeller-induced vibrations:
Counter-rotating propellers reduce vibrations and noise levels by counteracting rotational forces. This results in smoother and more comfortable voyages.
Increased comfort
Counter-rotating propeller configuration reduces blade load and noise levels in the propulsion system, making it ideal for vessels with low noise level regulations and high comfort requirements.
Smaller system diameter with same power
Counter-rotating propeller setup offers better control over thrust direction and distribution, improving maneuverability. Counter-rotating propellers help make tighter turns, navigate narrow waterways, and perform docking operations with greater precision.
Customizable configurations
Customizable counter-rotating propellers optimize efficiency by adjusting diameter, pitch, and speed for specific conditions.
