This from New York 1:

The City’s Economic Development Corporation has issued a
request for proposals for ferry service to the Williamsburg and
Greenpoint waterfront. The agency is currently reviewing the proposals.
New York Water Taxi is one company that wants in.

"The city provides a base level of operating subsidy. Together you
can make the system work, at a cost, that will bring people to the
water,” says New York Water Taxi President Tom Fox.

The Water Taxi already docks at the Schaefer Landing Condo Complex
in South Williamsburg and goes to Midtown and Wall Street. But there is
no city subsidy, so a one way ticket to Wall Street is $5.50, to East
34th Street is $4.50, compared to $2 for the subway. One rider says
it’s still worth the cost.
