Becker Twist rudder

The Becker Twist Rudder is a fully balanced rudder with a twisted rudder profile designed to interact with the rotating water flow leaving the propeller. A conventional rudder has a symmetrical profile and is designed for a straight inflow, even though the propeller flow is, in practice, rotating. This creates uneven pressure conditions across the rudder surface, which can lead to cavitation, erosion, and unnecessary energy losses. The Becker Twist Rudder, on the other hand, is designed to follow the natural movement of the propeller flow. The twisted rudder profile provides a more even load distribution across the entire rudder surface, allowing the rudder to operate effectively even at larger rudder angles and higher speeds. At the same time, hydrodynamic efficiency is improved by reducing energy losses in the propeller flow.

The fully balanced design also eliminates the wobble that occurs on many conventional rudders. This reduces the risk of vortex formation, gap cavitation, and localized erosion damage. The result is lower fuel consumption, reduced noise levels, less wear, and reduced maintenance requirements over the rudder’s service life.

When is a Becker Twist Rudder appropriate?

The Becker Twist Rudder is specifically designed for vessels with relatively high operating speeds and stringent energy efficiency requirements. The rudder is therefore particularly well-suited for:

• Container ships
• General cargo ships
• Ro-Ro and car carriers
• Passenger ships
• Gas tankers

For vessels where low fuel consumption, limited cavitation, and high hydrodynamic efficiency are key design requirements, the Becker Twist Rudder is a natural choice.
