Hydro Spoiler

Home » Hydro Spoiler

ENHANCED COURSE-KEEPING CAPABILITIES

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 8%.

At DMC, there are three types of hydro spoilers to choose from:

  • HD-B, known as our “standard” spoiler.
  • XR-B, this type is designed with a bulb for resistance reduction.
  • XR-T, this type is designed with a bulb with streaming body to intercept the entire wake field from the propeller.

ADVANTAGES

  • Improved speed performance
  • Reduced noise and vibrations
  • Improved vessel efficiency up to 8%
  • Enhanced course-keeping capabilities
  • Optimised water flow towards the rudder

APPLICATION

Suited for twin screw vessels.

  • HD-B spoiler available for propellers up to 1550 mm
  • XR-B and XR-T spoilers available for propellers from 1600 to 2000 mm
