SITUATION AVOIDANCE SYSTEMS FOR MARINE VESSELS

A control unit for controlling a marine vessel (110) to avoid an emergency situation, the control unit comprising processing circuitry and a storage medium, wherein the control unit is arranged to receive path data from one or more sensor devices indicative of a path (T) travelled by the marine vessel (110) in a forward direction (F) and to store the received path data by the storage medium, characterized in that the control unit is arranged to receive a trigger signal from an input device, and, in response to the trigger signal, determine a location (L) for turning the vessel (110) around, navigating to the location (L), turning the vessel around at the location (L), and navigating the vessel (110) along the path (T) in reverse direction (R).
