Product Features
Advantages of Contra-Rotating Twin Propellers:
The aft propeller effectively recovers the rotational energy of the forward propeller's wake, improving overall efficiency while reducing vibration and noise.
Proven Performance:
Sea trials have confirmed cavitation-free operation under free-sailing conditions, with significant reductions in noise and vibration. Compared with conventional single-propeller azimuth thrusters, efficiency is increased by 20–25%.
