The Sixth Borough is the harbor, says the blogger who calls himself Tugster.
I have taken a lot of pictures of tugs and barges - from North River 2 mostly - but Tugster has made it an avocation.
Based in Staten Island he is well situated for his observations. His interest reminds me of the days when the Times daily showed scheduled sailings and arrivals of steamships, and described their cargo.
The bridge is the Bayonne Bridge,and the Coast Guard ship is the buoy tender Ida Lewis.
The first and last of these shots are mine, the others are Tugster's. I expect to come back to his site. It's got lots of good shots - like the salt depot, barges, and cranes that I'll probably do as a post.
So check out TUGSTER
