Thanks for your patience; this follows up the post from two days ago.  The port is Boston, the date is November 1960, and the fleet tied up at the T wharf.  Luna, pictured below, is still extant; the others . . . I believe are all gone.

Above in the distance and below, that’s Orion.

I have no ID on this gentleman in Orion‘s engine room, or

this gentleman in the wheelhouse of another era.

Allan Seymour went on to a career as a professional photographer, and he sent me these photos.

Here’s how I first saw two of the boats–including Luna–back in 1987.  Here’s a report on the historic value of Luna submitted to the Boston Landmarks Commission in March 1985.

Thanks for your guesses, both here and on FB.  For the Boston Public Library’s trove of T Wharf photos, click here.   And here is the motherlode, at least 150 photos of Boston tugboats from the Digital Commonwealth collection.
