More than two years on from a public vote to name the city's newest ferries, Transport NSW has announced that Ferry McFerryface will, officially, hit the water.

"Ferry McFerryface will be the harbour's newest icon, and I hope it brings a smile to the faces of visitors and locals alike," Minister for Transport and Infrastructure Andrew Constance told the ABC. "This one is for the kids."

For the record, Boaty McBoatface actually collected the most votes in the Name Your Ferry competition, following on from a British poll to name a UK polar research vessel a few months before Sydney's boat-naming competition.

Although the UK's Natural Environment Research Council ignored the will of the public, deciding to name their boat the RSS Sir David Attenborough, our transport department nevertheless saw fit to avoid a double-up. "Given Boaty was already taken by another vessel, we've gone with the next most popular name nominated by Sydneysiders," Mr Constance says.

Over 15,000 different names were submitted to the competition. Three of the six already chosen are the Victor Chang (after the late heart surgeon), Fred Hollows (optalmologist) and Catherine Hamlin (obstetrician).
