Therefore, one suggestion when navigating in the wide sea area heading from the sea off Cape Muroto to Osaka Bay,would be to follow the traffic system from Shionomi to the Naruto Strait, and to position the vessel in the wide watersto the south of Hinomisaki, and to then take a course allowing a successful fade out in the sea area off Hinomisaki.It is true that the vessels heading towards the Naruto Strait navigate in a line, but as in the same way as a car trying toget on to an express way, it is possible to find gaps in the traffic.
