The XR rudder is especially developed for optimal propulsion efficiency in combination with first-class manoeuvring characteristics, which comes from rudder angles up to 80 degrees. The design of the rudder is cost- and fuel efficient. The rudder trunk is eco-friendly and requires low maintenance.
The XR rudders are optimally positioned in the propeller slipstream. This maximises the vessel speed with reduced vibrations and sounds. The rudder profile is developed to lower resistance and is therefore fuel saving.
To further optimise the propulsion performance, one should consider the complete Van der Velden® FLEX Tunnel package, which includes the Van der Velden® XR rudders, the Van der Velden® XR hydro spoiler and the Van der Velden® FLEX Tunnels.
DMC has developed an innovative retractable tunnel system, especially developed for inland vessels.
The concept behind the Van der Velden® FLEX Tunnel is its ability to retract. The tunnel can be retracted and embedded into the vessel hull whenever necessary. This reduces the overall resistance and increases the efficiency of the vessel.Read More
