If you are familiar with canals, you can see the similarities between this type of drydock and any canal lock that raises or lowers boats over varied terrain. This drydock will be sunk out of the way leaving the boat afloat when the job is done. The boat is small as towboats go.
We're back in Cape Girardeau for the week. My husband's work brings us here for about a week every month. Cape is 114 miles south of St. Louis, right on the Mississippi.
I find river life interesting. Also in this area, natural areas within an easy drive in both Missouri and across the river in Illinois are plentiful and varied. Lots to do here.
Also, if you are thinking of relocating, they sell earthquake insurance here. The New Madrid Fault is right here and there were huge quakes in 1811-12 that relocated the river.
