Adding 2 hours to a daily rest/ferries

Thanks. …forums like this are so useful to air issues like these.
…you hear so many conflicting theories on just about every ferry crossing about the ferry DR regs Wheelnut. Some drivers I worked with on DHL irish out of newark worked a 15 day in Ireland and back to the dock,- took the 0215 Holyhead on ferry DR, drove off the ship on disembarking ferry mode till the full movement hour clocked up -stopped anywhere from Bangor to Chester services! When at 11 hours total ferry DR time then on the next ‘card’, carried on to Newark swapped trailers drove back to Holyhead and took the 2130 stena back to Dublin on ferry DR. Did it week after week for months. Every one at DHL Newark transport thought they were legal. My oppo and I took a reduced DR on Dublin dock, 0820 Holyhead on next ‘card’ needing a trailer swap at Risley, Manchester to stay legal to get back to Holyhead for the 2130. We were treated with contempt coz they had to ship our trailers out to us every Tuesday turnaround-day. !
