A calculation of optimum ship route is carried out by using the data of sea condition experienced by a high speed single-screw container ship, the "Kashu-Maru". The effectiveness of the calculation method is verified by comparing the calculated results with the records of the "Kashu-Maru". Simulation of navigation in the North Pacific Ocean is also made and the problems awaiting improvement are discussed about the calculation method of optimum ship route.
