The arrangement (12) comprises a computing unit (29), where a measuring device (27,28) is configured for determining values of a physical size of a rudder. The measuring device measures the bending stress or torque of the rudder. The computing unit determines the force acting on the rudder according to the determined values of the physical size. Independent claims are also included for the following: (1) a method for detecting an acting force, particularly buoyancy or resistance on a rudder, particularly spade rudder of a watercraft, particular ship; (2) a dynamic positioning system for automatic positioning of a watercraft, particularly a ship; (3) an autopilot system for automatic track control of a watercraft, particularly a ship; (4) a method for dynamic positioning and automatic track control of a watercraft, particularly a ship; (5) a computer program product; and (6) a computer readable storage medium. |
