That's the Intrepid Museum, which has its own Concorde, as Flight 1549 floats by. The plane hit maybe a 1/4 mile up the river from there perhaps 90 seconds before. The boats you see there are just arriving.
And I can't help but imagine standing on the pier checking out the Concorde, thinking about the modern miracle of jet flight, then turn around to look out at the river and.... hey, is that a.... plane?
Here's a better pic of the Concorde at the museum - from this angle, there's a good chance you're actually looking at the impact spot behind it.
