The Log book
During the process of its operation, ECDIS automatically maintains two different electronic
logbooks:
•
Voyage record.
•
Twenty four hours logbook.
The voyage record stores every two hours the position, speed and course of the ship for half
a year.
Ú
Note:
This logbook is copy protected and cannot be deleted.
The twenty-four hours logbook records both navigational events and system events. It is also
possible for the navigator to make manual entries in the logbook.
The logbook entries are divided into 24 hours. Automatically at 24.00 hours each day the
current logbook is closed and stored in the logbook database and a new one created.
