Retractable Swing Thrusters

We developed the first swing retractable thruster in the world. Our retractable thrusters are available in four model sizes ranging from 25 HP to 200 HP.

In the ejected mode the retractable thruster works like a conventional thruster. In the retracted mode a plate welded to the thruster tunnel covers the opening in the hull ensuring a minimum of added resistance. This feature is especially popular in the sailing yacht industry. As standard the housing is manufactured in aluminum and it comes with a three or four bladed propeller in either aluminum or nickel aluminum bronze. The prime mover is hydraulic and the retraction mechanism is either electrically or hydraulically activated.
