Bow thruster

sternfor boatstwin counter-rotating propellers

WESMARs commercial line of robust counter-rotating dual propeller thrusters sets a high standard in the commercial bow thruster industry by bringing more power, less noise and less vibration than competitive units. The use of counter-rotating dual propellers splits the power between two gear sets thus yielding a very high propeller efficiency. The aft propeller recovers the swirl energy left behind by the forward propeller creating greater power and more thrust.
