Optimizing
performance
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.
