Powerful and Easy to Install Bow + Stern Thrusters

No matter what weather you’re in, Sideshift is there to help guide your boat home safely and easily, every time. Our pivot point advantage and unique prop-in-water design deliver stronger, more immediate performance for an installed cost up to 50% lower than conventional tunnel thruster systems. In stressful docking situations where seconds count, Sideshift delivers the performance you need.

Sideshift’s family of Monohull Bow + Stern Thrusters are perfect for all boats from 20’ to 60′ in length. They mount easily on the bow or stern of cruisers, sport boats, sailboats, catamarans, trawlers and more. No expensive tunnel is required, and our unique universal mounting system requires no holes below the waterline, eliminating the risk of leaks associated with all other types of thruster systems. Did you know that according to BoatUS Insurance, a full 44% of sinkings are a result of failed fittings below the waterline?

Silent and immediate response is provided by our prop-in-water design, 8” aluminum propellers, and heavy-duty water cooled motor. Saltwater proven, our rugged bow + stern thrusters are anode protected to prevent corrosion.

Maneuver confidently into the tightest slip with a simple touch of the wireless joystick.  Step onto the dock while maintaining total control of your boat with our wireless key fob controller.

Shipped as a complete kit with thruster, controller, mounting hardware and wireless joystick, installation takes less than a day.

Are You Docking Like a Pro, or Being the Shore Entertainment?

Does the thought of taking your boat out on the water on a windy day make you more stressed out than excited? Are you using your boat less and less because of your fear of docking?  You are not alone.

Docking can be one of the most stressful experiences you will face as a boat owner. Worrying about damaging your boat or your neighbours boat can turn a beautiful day on the water into a stressful nightmare.

That’s where SideShift can help. Most of our customers purchase a SideShift thruster system for one or more of the following reasons:

  • I Want to Be Able to Park My Boat with Confidence:  Slips are getting tighter, and there are times when the wind just won’t cooperate.
  • I Want to Stop Worrying about Damaging My Boat and My Neighbours Boat:  Our boats are major investments and I don’t want to risk damage every time I want to go out on the water.
  • I Want to Be Confident Exploring New Places:  I bought my boat so that I could explore new waters, but I need more precise control to navigate unknown marinas and locks with confidence.
  • I Want to Be Able to Dock in Any Condition:  Windy conditions make docking too unsafe for me to manage on my own or with my spouse.
  • I Want My Boating to Be Fun, Including Docking:  Boating is fun, but docking is stressful and I’m tired of the anxiety that comes with docking in difficult conditions.

Do any of these points hit close to home? Then a Sideshift thruster system might be the perfect answer for you.

Ultimate Control

No matter what weather you’re in, Sideshift is there to help guide your boat home safely and easily, every time. Our pivot point advantage and unique prop-in-water design deliver stronger, more immediate performance than conventional tunnel thrusters. In stressful docking situations seconds count, and Sideshift delivers the performance you need.


World-Class Support

For over a decade, thousands of customers in over forty countries have put their trust in Sideshift bow and stern thrusters. Our success is no secret. All of our products have been purpose-built for the most extreme weather conditions. Using only the highest quality materials, we provide a comprehensive two year warranty and we back it all up with the most responsive product support team in the industry.


Why Sideshift Outperforms Other Docking Solutions

Our bow and stern thrusters rely on a revolutionary design pioneered by Sideshift that places the thrusters on the outside of the hull, rather than inside.

This unique design allows for quiet operation, better response and easy installation, all at a lower installed cost than any competing thruster solution.

Quiet Operaton:

Sideshift bow and stern thrusters are mounted externally to your boat, Unlike tunnel thrusters that have the motor mounted inside the hull producing significant noise and vibration, Sideshift thrusters are silent and vibration free.

Instant Response

Sideshift thrusters’ external mounting position places our 8” aluminum propellers in direct contact with the water, providing instant response when seconds count. Conventional tunnel thrusters have to move water through a tube or “tunnel” to provide thrust, which can delay response, wasting valuable seconds in a critical docking situation. In addition, our external mounting system places the thruster further forward or astern on the boat, which provides a pivot-point advantage and more immediate response.


When you buy a bow or stern thruster from Sideshift, you’re dealing with the industry pioneers behind external thruster technology. We help you every step of the way to ensure that you get the right product, along with unlimited phone support from our team of technical experts.

Our team at Sideshift has helped thousands of customers with every kind of boat and installation requirement. You can contact our customer support directly by phone any time.
