NYC Ferry's South Brooklyn route officially launches Thursday, but Mayor Bill de Blasio took a ceremonial first ride Wednesday.

The ferries will run between Bay Ridge and Wall Street, with stops at the Army Terminal in Sunset Park, Red Hook, Atlantic Avenue, and DUMBO.

The Astoria route is set to launch in August, with stops in Long Island City and on Roosevelt Island.

NYC Ferry began on May 1 with service between the Rockaways and Wall Street.

A one-way ride is $2.75, or $3.75 if you bring your bike.

A 30-day pass costs $121.
