1. Timetabled sailings but excluding any additional sailings operated by CalMac.
2. New performance measure for 2003-2004 covering the number of timetabled sailings actually operated taking account of any relief events agreed by the Scottish
Executive - for example, sailings which were cancelled due to bad weather; in accordance with safety procedures; delays due to the availability or operational restrictions of harbour facilities, or having to wait for the arrival of other public transport connections
3. Covers CalMac's punctuality performance against its published timetable taking account of any relief events. Performance measure was previously called Quality of Service.
4. NorthLink Orkney and Shetland Ferries Ltd started operating its services on 1 October 2002. Its figures for 2002-03 therefore cover only a period of six months.
NorthLink Ferries Ltd started operating its services on 6 July 2006 and includes freight services for the first time. The figures for 2007-08 relate to the 2007 calendar year. The reliability figures include services cancelled due to circumstances beyond the operators control, such as adverse weather, for which the operator can claim relief. From October 2002, the punctuality figures relate to services arriving within 20 minutes of the published timetable on the Pentland Firth services and within 90 minutes on the Aberdeen, Kirkwall and Lerwick passenger services.
The punctuality figures include services delayed due to circumstances beyond the operators control, such as adverse weather, for which the operator can claim relief.
From July 2006, the punctuality figures relate to services arriving within 10 minutes of the published timetable on the Pentland Firth services, within 30 minutes on the Aberdeen, Kirkwall and Lerwick passenger services and within 45 minutes on the Aberdeen, Kirkwall and Lerwick freight services.
The punctuality figures include services delayed due to circumstances beyond the operators control, such as adverse weather, for which the operator can claim relief.
