Random Randomness on the St. Clair

These items aren't particularly random though.  Just things you'd expect to see on the river.

 A pleasure boat of some sort.  With the weather getting nicer, the fishermen are coming out.

 A pontoon boat.

 The Marine City ferry again.

Now this one is pretty random.  It is a barge with a crane pushed by some sort of vessel.  Maybe someone wanted to cobble together a self unloader...I don't know.
