2 minutes to get onto a ferry! Lucky
If you can post a copy of your print out (blanking your name and reg) maybe we can see any error.
Just to check, on the day you shipped:
Start 10hr30.
End 18hr15.
At 18hr15 stop and select bed
21hr45 select ferry and move for 2 minutes
21hr47 stop and select bed
00hr30 (approx) select ferry and move off boat
00hr50 stop and select bed.
09hr15 book on and enter duty.
If that`s it, seems OK to me.
