"There's no need to fear......."

Niantic, CT

Those of us who grew up back in the 60's and early 70's can complete the title of this post.  This is a very unique boat and certainly one I have not seen before. Usually you can tell by looking what type of boat  it is, whether it be a pleasure craft, a fishing boat, a tugboat, or dredger.  I have no idea what this boat is used for.  It must have some very specific use necessary for bridge building or bridge demolition.  I can see this boat coming to the rescue, but exactly what type of rescue, I'm not sure.
