1. A ship state prediction system comprising a processor, a wave sensor system and a display connected to the processor,
wherein the wave sensor system is adapted to measure, in real time, wave fields and wherein the wave sensor system is configured for providing the measured wave fields to the processor;
wherein the processor is configured to; continuously determine a ship state prediction of a ship state in a future time period based on the wave fields measured at a current time, to determine an accuracy of the ship state prediction in the future time period, to determine a maximum prediction time in the future time which corresponds to a the future time period where the accuracy drops below a pre-set accuracy, and to generate a ship state visualization to be displayed on the display;
wherein the ship state visualization comprises a time axis comprising a time range including the current time and the future time period, relative to the current time;
wherein the ship state visualization comprises a representation of the ship state prediction which is displayed on the future time period of the time axis; and
wherein the ship state visualization comprises an indication of the maximum prediction time.
