[[File:DUBLIN(1837) p131 SARAH'S BRIDGE, ON THE RIVER ANNA LIFFEY.jpg|thumb|"Sarah's Bridge on the River Anna Liffey" (1831) Sarah's Bridge is today called [[Island Bridge]]. The then-new [[Wellington Monument, Dublin|Wellington Monument]] is seen on the left]]
A well-known sight on the Liffey up to the 1990s, the ''Lady Patricia''<ref name="guinnessboats">{{cite web | url = http://www.irishships.com/guinness_boats.htm | publisher = IrishShips.com | title = Background on the Guinness boats on the Liffey | archive-url = https://archive.today/20060319215736/http://www.irishships.com/guinness_boats.htm | archive-date = 19 March 2006 | url-status = dead }}</ref> and ''Miranda Guinness''<ref name="guinnessboats"/> [[cargo ship]]s were used to export [[Guinness]] from the [[St. James's Gate Brewery]].

As of the early 21st century, the only regular traffic on the river within the city is the ''Liffey Voyage'' water tour bus service, which runs guided tours along the River Liffey through Dublin City centre. Departing from the boardwalk downstream of the [[Ha'penny Bridge]], the ''Spirit of the Docklands'' was built by ''Westers Mekaniska'' in [[Sweden]] as a 50-passenger [[water taxi]]. Its variable [[ballast tanks]] (not unlike a [[submarine]]) and low [[air draft (nautical)|air draught]] mean that at [[low tide]] it can float high, but at [[high tide]] it can ride low and still pass below the Liffey's bridges.

Downstream of the East-Link bridge, the river is still mainly used for commercial and ferry traffic, with some recreational use also. High speed trips out the mouth of the Liffey were also previously available from Sea Safari.<ref>{{cite web | url = http://www.seasafari.ie | publisher = Sesafari.ie | title = Sea Safari | access-date = 20 August 2017 | quote = "''Tours Suspended for 2016''" | archive-date = 13 June 2006 | archive-url = https://web.archive.org/web/20060613184924/http://seasafari.ie/ | url-status = live }}</ref>
