Engineered for Maximum Efficiency and Reliability

Every Sleipner thruster is designed with performance, efficiency, and longevity in mind. Key design features include:

• Hydrodynamic gearlegs that minimize drag and resistance, maximizing overall system efficiency

• Clean, streamlined housing design to optimize water flow and reduce turbulence

• Optimized tunnel and propeller geometry for maximum thrust output

• 5-blade bronze Q-Prop™ propellers for:

  • Reduced noise and vibration

  • Increased efficiency and thrust

  • Lower risk of cavitation

  • Smooth, predictable maneuvering

Comprehensive Thruster Solutions for Commercial Applications

Sleipner offers one of the industry’s most complete ranges of commercial thrusters, covering everything from compact workboats to large commercial vessels:

• Hydraulic Thrusters:
  Available in tunnel diameters from 7¼” to 29”, delivering 220 lbs up to 4,800 lbs of thrust for precise, powerful maneuverability.

• AC Thrusters:
  Offered in 10” through 29” tunnel sizes, providing dependable performance for larger vessels and continuous-duty applications. A new Permament Magnet motor option will be available for the larger sizes (700 kg thrust/16" (410 mm) tunnel sizes and up.

• DC Thrusters (E-Series)
  Proportional 24V and 48V DC thrusters in 8½”–12” tunnel sizes, delivering up to 770 lbs of thrust, with runtime limited only by onboard battery capacity. Brushless Sleipner-engineered motors, lightweight bronze gearlegs with composite Q-Props, ignition protected, splashproof, and joystick-ready via S-Link CANbus.

• Commercial Certification:
  All commercial-grade thrusters are DNV approved, meeting strict international standards for safety, reliability, and performance.

• Service-Friendly Design:
  Larger models feature optional in-water gear oil change capability, reducing downtime and simplifying routine maintenance.
