PURPOSE: A method for calculation vessel navigation information is provided to transfer a vessel to a fixed specific location or a moving specific location, by calculating recommended course, a recommended speed and turnaround time. CONSTITUTION: Minimum distance to the area of figure showing the navigation location of a moving vessel is calculated(S910). Relative speed of the vessel is calculated for the transfer speed of the figure area(S920). Transfer turnaround time initial value of the vessel is obtained from a mathematical equation(S930). Distance to the shortest distance spot of the figure area at the transfer position of the vessel is calculated(S940). Required transfer speed of the vessel is calculated by dividing the shortest distance by the transfer turnaround time(S950). The difference between the required transfer speed and the speed of the vessel is compared with a value of a fixed range(S960). The shortest distance spot is calculated from the location of the vessel transferred from a final transfer location of the figure(S970).
