We have seen the Alpina a few times, but I don't have access to her schedule. It is regular because that whole fascility to the left of the ship in the picture is for unloading her. Virtually every weekend since we discovered this app there have been 600 foot freighters in Cleveland, some going way up the crooked river. How they get around these bends is really amazing, some times involving a tug, but most go with just thrusters. Nicely they have to go slow enough for 1 or 2 second exposures around the bends. To me what is interesting is how far out of whack they throw the scale of things; big ship, small tug, tight corners, low bridges, the communication between the ships and the lift bridges. 100 car trains stop to let the ships pass under a bridge. It has become a major part of this year's 7x17 photo series for me.
As I write there are two ships in Cleveland:
Calumet, 192 meters
Lee A Tregurtha, 237 meters
and the Sam Laud, 194 meters, passing Detroit on her way to Cleveland in the morning
