Methods and systems are disclosed for determining a power distribution of a propulsion system of a vessel with a propeller and a hull, the propulsion system comprising a plurality of power sources, preferably hybrid power sources, for powering one or more engines for driving the propeller. The method may comprise receiving a shaft speed set-point (302) defining a target rotational speed or target effective rotational speed of the propeller. The method may further comprise determining an advance ratio (306) of the propeller based on the received shaft speed set-point and one or more design parameters of the propeller and/or of the hull, determining a propeller torque parameter (310), preferably a propeller torque or a propeller torque coefficient based on the shaft speed set-point and the advance ratio, and determining a predicted load (312) based on the determined propeller torque parameter, the predicted load defining an estimated load of the propeller when rotating at the shaft speed set point. The method may further comprise determining a power distribution based on the predicted load. Determining a power distribution may comprise selecting a power source, the power distribution defining an amount of power to be delivered by each of the plurality of power sources.
