A calibration method for at least one propulsion unit of a marine vessel, the at least one propulsion unit being arranged to provide a propulsive force to the vessel, the at least one propulsion unit being adjustable so as to change a respective steering angle of the at least one propulsion unit in relation to a hull of the vessel. The method includes controlling the at least one propulsion unit so as to provide at least one acceleration sequence, wherein the vessel is accelerated stepwise or continuously in each acceleration sequence, adjusting, continuously or repeatedly, during the acceleration sequence, the steering angle of the at least one propulsion unit, to keep the path of the vessel straight during the acceleration sequence, registering, during the acceleration sequence, a plurality of values of the respective steering angle of the at least one propulsion unit, and determining, based at least partly on the registered steering angle values, a respective reference steering angle of the at least one propulsion unit, which reference steering angle minimizes a deviation of an actual course over ground of the vessel from a desired course over ground of the vessel.
