By Martin Robinson PUBLISHED: 06:34 EST, 17 June 2013 | UPDATED: 04:26 EST, 18 June 2013 A couple who drove 270 miles across Britain to catch a 20-hour cross-Channel ferry to Spain ended up on a tiny ten-minute commuter boat instead after following their sat-nav. Pensioners Bob and Pat Banks had booked themselves on the £100million Pont Aven from Plymouth to Santander in Northern Spain but then got stuck on the nearby Torpoint ferry after a wrong turn. They were due to join 2,400 holidaymakers on the overnight crossing on the huge Brittany Ferries' flagship, but accidentally took a boat which held 70 cars and ferried them to Cornwall for £1.50.
