This paper presents two models for determining the probability of deciding relative distance measured with the eye and the approximation by power function. The decision-making on the sea takes place in an environment in which states of nature, psychology, physiology and available information are fuzzy. Therefore, the models are based on the application of the fuzzy sets theory, the statistical probability theory and the entropy theory. The calculation performed by using the results of questionnaire about the far and near sense against target ships. The calculation results agreed well with the experimental concerning the distance of vision at sea.
