The bow thruster installed on my fifty-foot Gibson Cabin Yacht is performing well and has made a great difference in our enjoyment of the vessel. – Mike Ford, San Antonio, Texas, Gibson Cabin Yacht. – GARY JENKINS

Powerful and easy-to-install bow and 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 of 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 and 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 and stern thrusters are anode-protected to prevent corrosion.

Maneuver with confidence into even the tightest slips 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.
