This paper is intended as an investigation of the evasive area around a ship which a navigator would like to keep free with respect to other ships as defined by Ms. Goodwin. Authors assume that the boundary of the evasive area is an ellipse around a certain ship and the distribution of ship's paths is a normal distribution. From both of the theoretical considerations for the evasive area and the radar observations in the KANMON Strait and the KURUSHIMA Strait, it was confirmed that the density distribution of the relative positions of the following ships was represented in the normal distribution with changing σ according to the distance from the preceding ships. Furthermore, it became clear that there was a difference in the size and the shape of the evasive area between the above two observation areas.
