Abstract
The large ferry boat of navigating liner route around for the Japanese coast is performing an important role as a cargo of transportation. Moreover, maritime transportation draws attention as a favorable system for the modal shift. Consequently, the security of the ships that navigates Japanese coast becomes important. The past investigation showed that ship motion become large near the cape sea. We get the information from Navigator's that the wave near the cape sea is high in comparison with other places and dangerous. In this paper, we calculate wave transformation near Muroto cape sea, and compare with navigator's wave information. Moreover, using the result of a calculation, the system which provides waves information for the navigating ship near the cape is proposed.
