An exemplary method is disclosed for estimating operational efficiency of a marine vessel with a propeller mounted to a rotatable shaft for converting rotative shaft power transferred from the shaft to the propeller into thrust to propel the marine vessel across water, the method including obtaining a respective time series of values for operating parameters of the marine vessel; constructing a multi-dimensional power matrix for a first time period based on operating parameter values within a respective sub-series thereof that represents a first time period; computing, for one or more propulsion parameters, fouling values based on information stored in the power matrix and information stored in a base matrix, of a reference fouling level; and creating indications concerning operating status of the marine vessel in dependence of the fouling values.
