Only done this the once but here’s the way I was told to do it.
- Book off once on the boat in the country of departure.
- Set the tacho to boat/train mode.
- Once the crossing is over don’t touch the tacho and drive off the boat and once you’ve parked up book off in the country you are now in.
Seemed simple enough to me and the tacho seemed ok with it because it was happy with the break and didn’t go mental once I finally started my new shift.
Cheers
