A ship needs a course line in order to perform navigation safely and efficiently. If we could set a suitable course line automatically, it would relieve burden of the navigator and reduce maritime casualties such running aground. In this paper, the author proposes a method to set a course line from the shape of available water area. The procedure of this method is as follows : 1) Select the available water area 2) Extract the Medial Axis from the available water area, and assume the network on it 3) Calculate the shortest path between the origin and the destination, and calculate inscribed radii of points that form the Medial Axis 4) Pass the shortest path through the filter that utilizes the inscribed radii Utilizing this simple method, some examples of course line on practical water area are shown. As a result, it was found that the method is useful on restricted water area such harbors and narrow channels. In addition, the method could be applied to estimation of the water area network.
