The article describes a method used to create an on-board measuring system to determine the degree of risk in towing operations using the mathematical apparatus of fuzzy logic. Based on the method of paired comparisons and transformations and using the interpolation method, membership functions of linguistic variables for determining the degree of risk were calculated. To eliminate the misperception of control commands in the tug in towing operations, the concordance component of risks was used. This method was used to assess the risk value for mooring with several operations. The on-board measuring system for risk assessment was developed. Its main component is a data bank containing factors that affect an assessment of the state and results of the fuzzy logic unit. The system can assist skippers in the decision-making process in shipboard operations. The fuzzy logic system was tested by interviewing maritime workers; the result proved the adequacy of this system.
