The Fastnet Line ferry service on the Swansea to Cork route saves 600km (375 miles) driving on a round trip and connects the M4 Motorway in the UK directly to Cork on Ireland's South coast. The service offers  comfortable overnight sailing 6 nights a week (Tuesday, Thursday & Saturday from Cork and Wednesday, Friday & Sunday from Swansea) departing  generally at 21:00 and arriving at 7:00 the next morning. Occasionally these times vary due to tidal conditions in Swansea but these are advised at the time of booking.
