Hoy is accessed from mainland Orkney by way of a short sea crossing provided by Orkney Ferries.  This provides a frequent vehicle & passenger service from Houton to Lyness and an early morning/early evening pedestrian/cycle ferry to Longhope. The winter and summer timetables are different - there is no Sunday ferry in the winter.
