BOSS™ Stern Force Measurement (SFM)

In general, all rudder movements create resistance, which automatically increases fuel consumption. BOSS™ SFM gives insight into the steering behaviour and resistance created by the rudder. It measures the rudder force acting on the vessel. The measured data is send to the SFM display, which is located in the wheelhouse, and can be transferred to the ship's navigation system.

With the real-time data of BOSS™ SFM you can improve the course of the ship by reducing rudder movements .This results in significant fuel savings and improved manoeuvrability.

It is advised to combine BOSS™ Dmc Cloud Connect (DCC) and Data Logging Function (DLF) with the SFM application to log and access the measured data. This allows to access past and present measurements at all times and at a remote location.



  • Can reduce rudder movements and fuel consumption
  • Continuously measures and displays the real-time rudder force
  • All data can be logged and accessed in the cloud with BOSS™ DCC and DLF
  • Allows insight into the steering behaviour and the resistance created by the rudder


  • All vessels with a rudder system, both newbuild and for retrofit
