Lough Area of Special Scientific Interest but within the immediate harbour area the boundary has been redrawn to take into account permitted port related development and landfill which has taken place since the Inner Belfast Lough Area of Special Scientific Interest was declared in 1987. Marine areas below mean low water are not included. The Ramsar boundary entirely coincides with that of the Belfast Lough Special Protection Area. The site qualifies under Criterion 3c of the Ramsar Convention by regularly supporting internationally important numbers of common redshank in winter. The site also regularly supports nationally important numbers of common shelduck, Eurasian oystercatcher, purple sandpiper, dunlin, black-tailed godwit, bar-tailed godwit, Eurasian curlew and ruddy turnstone. Sailing Popular for sailing, the lough has three marinas: one at Bangor, one at Carrickfergus and a third located at Titanic Quarter. Belfast docks at the head of a lough contain the famous shipbuilder of the RMS Titanic fame, Harland & Wolff, who are no longer building ships for the foreseeable future and has shed most of its workforce and diversified into repairing and refitting large tankers and oilrigs. Coastguard offices for the lough, although referred to as Belfast Coastguard, are in the town of Bangor by the marina. In 1912, the RMS Titanic sailed down the lough from Belfast to the Irish Sea for its sea trials. The lough hosts two Royal Yacht Clubs. One at Cultra just outside Holywood, The Royal North of Ireland Yacht Club, and the Royal Ulster based from Bangor. There are also several other clubs spread around the lough: Ballyholme Yacht Club, Carrickfergus Sailing Club, Cockle Island Boat Club, County Antrim Yacht Club, Donaghadee Sailing Club and Holywood Yacht Club. For racing sailors, this is a competitor's dream, giving of open water and enough coastline to make short inshore races day-long affairs. Three main arteries serve the lough close to Belfast: the Herdman Channel on the County Antrim coast side; the Victoria Channel, the central and longest route; and the Musgrave Channel on the County Down side. Railway The Belfast-Larne railway line skirts the north shore particularly from Carrickfergus and then Downshire to Whitehead and northwards then alongside Larne Lough to Larne Harbour. Trains connect Belfast Great Victoria Street and Belfast Central to Larne Harbour. The Belfast-Bangor railway line skirts the south shore at Holywood railway station to Marino railway station and Cultra railway station. Trains connect Belfast Great Victoria
