The Ise Bay Ferry takes about 55 minutes for 20 km between Toba Port at Mie and Irako Port at Aichi (inside the red frame on the right figure).
Ise Bay Ferry is usually operated 8 to 9 navigations per day with another ferry.
However, if one ferry is in the dock, it will be different from usual time table. And it may have canceled at stormy weather.
We have set equipment in the Ise-maru, and observe flow and water quality of Ise Bay.
