Sylt Ferry operates 18 crossings a day between Havneby (Römö, Denmark) and List (Sylt, Germany), with each crossing on the MS SyltExpress taking approximately 40 minutes.

A ferry crossing has been in existence here since 1963: connecting List on the island of Sylt with the Danish Havneby on neighbouring Rømø, connected to the mainland via a road dam. The crossing became part of the FRS Group in 1979. In 2005, the Rømø-Sylt Line (RSL) deployed a new modern double- ended ferry on this route, the MF "SyltExpress".
