Van der Velden BOSS™eco.


The BOSS™ eco system consists of a touchscreen display with integrated software, which continuously calculates and shows the steering behaviour in relation to the steering movements and rudder angles, aligned to the actual sailing situation.

The BOSS™ eco system measures and shows the following: rudder angles, CO2 emission, fuel consumption per litre or kilometre, speed, rate of turn (ROT) and steering efficiency indicator (SEI). By giving insight into these measurements, it allows the captain to be more conscious of his or her sailing behaviour, which can lead to considerable fuel savings. Preliminary practice results show fuel savings of approximately 12%.

In addition, the BOSS™ eco system saves the data in a trip registration sheet. The data, which is collected per voyage, will be saved in an overview where you can directly compare your steering behaviour and efficiency. It is possible to send the data overview via e-mail, to save it or to print it.

Manoeuvring is necessary on inland waterways. Every rudder movement creates extra ship resistance and by preventing excessive steering corrections you can improve your transport performance (EOI). It is proven that, once the BOSS™ eco is used according to its functions, fuel savings up to 20% can be achieved.

The BOSS™ eco system is suitable for all types of vessel, both new built and retrofit, and is available in the languages English, Dutch and German. If not already present, DMC additionally supplies an accurate fuel sensor.



  • Considerable fuel savings

Barke Optimised Steering System (BOSS™)


The BOSS is able to calculate the rudder forces for specific angles, which are not measured or displayed by any of the ship’s navigation systems.

The BARKE® rudder is the solution if you are looking to invest in today and tomorrow.
