In historic photos the Arthur M. Anderson has lifeboats. Today it looks like she is configured with a rescue boat on the starboard side and life rafts on both sides. Are the lifeboat requirements for lakers different from blue water ships?
Look at the second picture. You can see why lifeboats (or rafts) are not much use on a Laker. 
It’s only like that in winter.
Do they sink in the summer too?? 
Historical tug still in existence:

I sailed on the slightly larger Maersk California which has a single rail crane instead of the 2 stationary ones on the Arkansas.

Those Leibherr cranes brought joy to a mate’s heart.
