New York City is seeking to overhaul its fleet of Staten Island Ferries with three new boats and upgrades to three others.
The city Department of Transportation put out a request for proposals this week. It's calling for new vessels to replace three of the older boats in its fleet.
The department is also seeking proposals to upgrade its remaining boats with new propulsion systems.
The Staten Island Ferry carries more than 21 million passengers annually between Staten Island and lower Manhattan. There is no fare.
The oldest vessel still in service is the John F. Kennedy, built in 1965. It is slated to be retired along with the Andrew J. Barberi and the Samuel I. Newhouse.
Proposals to design and construct new ferries are due Aug. 17.
