We get a huge load of Barge Traffic here and the occaisional freighter or Collier.
I used to work on a 100 foot Dinner Cruise Boat that ran between Newburgh and West Point. Each fall we'd head all the way down river to NYC, around the Battery, up the East River, through Hells Gate into the Sound where we'd head for Norwalk Ct and our winter home port. They had the closest Travel Lift big enought to lift her out of the water.
We'd spend all winter chipping, painting, rebuilding engines and generators, all kinds of maintenance. We'd meet the Lobstermen as they came in and pick up "culls" for a couple bucks a pound. Steamed Lobster nearly every night.
