A second Freshwater-class ferry will be retained for weekend use on Sydney Harbour.
The MV Freshwater will join the MV Collaroy in transporting passengers between Circular Quay and Manly on weekends from mid-year, when sister vessels MV Narrabeen and MV Queenscliff are retired.
New Emerald-class ferries will replace the Freshwater-class ferries on weekdays, which the NSW government says will be faster and more energy-efficient.
"Weekday commuters, who want faster and more frequent services, will be served exclusively by the new generation Emerald-class vessels, which are fully accessible, more energy-efficient and cheaper to run," Transport Minister Andrew Constance said in a statement on Friday.
Manly MP James Griffin says he is pleased the older boats will be retained for use by tourists and day-trippers travelling at a more leisurely pace.
The NSW government in November agreed to reverse the retirement of the entire Freshwater-class fleet, initially retaining the MV Collaroy until 2023.
Mr Constance in November said the Emerald-class ferries would enable the government to add more weekly services to the F1 Manly ferry route and save the government $6 million a year.
