Hydro Spoiler
The purpose of the Hydro Spoiler is to optimise water flow towards the rudder. A spoiler is placed behind the propeller, exactly on the centreline.
The curved blades catch the outflowing water from the propeller and bend it from a swirling to a straight outgoing flow towards the rudder, making the outflow of the propeller water more even. Smooth water flow towards the rudder results in reduced noise and vibration levels. The Hydro Spoiler improves the propulsion efficiency and speed performance of a vessel, and enhances the ship’s course-keeping capabilities. Continuous research and customer feedback since the introduction of the Hydro Spoiler in 1998 have proved that these refinements increase vessel efficiency up to 5%.
