Bow & Stern Thrusters

Thrusters for commercial vessels and luxury yachts from 30 feet to 500 feet

Built rugged for the toughest jobs in the most demanding environments

WESMAR's line of commercial grade counter-rotating dual propeller thrusters sets the standard in the marine industry.

The use of counter-rotating dual propellers, a WESMAR innovation, splits the power between matched gear sets thus yielding very high efficiency. The aft propeller recovers the swirl energy left behind by the forward propeller creating more thrust.

All bow thruster components exposed to seawater are made of stainless steel including the 4-blade Kaplan props, drive leg, shaft, bearings and seal carriers. The highest quality seals are fitted to the input and output shafts to prevent water ingress and oil leakage. All seals can be replaced without dismantling the complete thruster unit. This best in class reliability translates to enhanced safety for the vessel operator and crew.

WESMAR thrusters are available with a choice of DC 12V, 24V, 48V, AC Variable speed, or hydraulic power. These drive options are available with ON/OFF or proportional control.

WESMAR Thruster Standard Features:

• Commercial grade bow/stern thrusters, 5 to 500 horsepower
• Efficient 7-inch to 48-inch counter rotating dual 4-blade Kaplan props
• Investment cast stainless steel construction for maximum durability, reliability, and safety
• Thruster internals built with AGM matched spiral bevel gears
• Options: Pre-mounted in steel, aluminum or fiberglass tubes (saddle mount or weld-in)
• Counter rotating dual propellers provide the most thrust per input horsepower
• With more thrust, smaller tunnel diameters are possible minimizing hull space required as well as reducing drag and saving fuel
• Can be interfaced into a Dynamic Positioning System
• ABS/PDA (Product Design Assessment) design approval or other industry certifications are available if required
• Low maintenance
• Overbuilt for reliable operation
• Multiple control stations can be provided with on-off or proportional controls.
• Easy Retrofit: Upgrading your thruster is simple and easy! WESMAR's two bolt design allows for a simple drop-in retrofit on existing metric sized tunnels. Both the V2-7M and V2-10M models are drop-in replacements for Max Power, Side Power, and Vetus thrusters.
• Best in class quality of design and construction make WESMAR thrusters a long-lasting investment.
• In-Hull mounted motor design facilitates easy access and maintenance, upgrades, and isolates the power source and hydraulic oil from seawater
