Sixth Boro Fifth Dimension IS4

For context in this series, IS2 is most explicit, but for fun, check them all here.  The photos in this series, all scans of slides,  were all taken after the late 1950s.

#1.  This is called Hudson raft-up.  My questions:  Can anyone identify the tug or at least its company?  Is that a steam crane on the nearest barge?

#2.  Lightship Scotland.  Click here for a great story about bypassing the fishing regulations in the vicinity of the Scotland light, named for a 19th century wreck at that location.   Some questions:  Is that the current Ambrose at South Street Seaport?   Which lighthouse/lightship tender would that have been in the New York Bight?  What might the smaller USCG vessel be?

#3.  USS Saratoga CV-60, launched NY Naval Shipyard in spring 1956, i.e., she was fairly new when this photo was taken. Only two more carriers would be built at New York Naval Shipyard in Brooklyn.  After service until 1994, she was decommissioned and plans were made to transform her into a museum, but those plans collapsed and she has been sent to scrap.   For photos by Birk Thomas of CV-60 departing for the scrapping, click here.

Many thanks to Ingrid Staats for allowing me to publish these photos here, where I hope group sourcing brings more info to light.
