Ferry trips longer than 1 hour must be recorded as a Break in your logbook.
Steps
When the ferry departs, tap BREAK
When the ferry arrives, continue working (tap DRIVE or OTHER DUTY)
If you have used all your work-time, you must park safely within 1 hour of arrival. Then tap End Shift and take your 10-hour rest.
Tip: If you go over your work-time limit because of the ferry, add a comment explaining the ferry trip. This helps if an officer reviews your logbook.
