Blasio’s ferry is feeling $ea sick

Ridership on Mayor de Blasio’s signature East River ferry service is sinking fast amid the coronavirus pandemic — dropping by 80 percent, according to figures obtained by The Post.

“Sometimes, I see three people on the boat — the captain and two crew members,” said a mariner who views daily pickups and dropoffs at the Red Hook, Brooklyn, dock that is part of the New York City Ferry Service.

The data show that just 19,851 riders used the heavily subsidized service in the last week of April, or 2,836 passengers per day on its six current routes.

That’s down from 97,256 for the last week of April 2019.

The city paid private operator Hornblower $52.95 million between July 2018 and June 2019 to run the service, according to the most recent figures available.

The de Blasio administration also spent $82 million to buy 19 boats.

All the current routes have stops at Wall Street/South Street Pier 11, and a visit there one morning last week found few passengers disembarking from ferries during the rush hour of 8 a.m. to 9 a.m.

Medical workers were among the few still using the service.

Critics have complained that the ferry service is too highly subsidized for a service typically used by well-to-do commuters — with twothirds making more than $75,000 a year, according to city Economic Development Corp. surveys.

City officials said service has been reduced during the pandemic to adjust for lower ridership.
