Ditterke,
Very convincing work! I've been thinking about barges for a long time. My first river scene, built in 1992, showed two coal barges that were out of control in the current, and were being pushed back into position by their tug and a Coast Guard cutter. Now I am modeling a seaport, Portsmouth, NH, where barges would not work very well, as there are few protected waters outside of the harbor. In my modeling era of the 1950s, barges were heavily used for the transport of bulk materials on protected waterways. In Portsmouth, they were used inside the harbor, and all along Great Bay, to carry bulk materials from one part of the harbor or Bay to another part. Further north, in Casco Bay around Portland, Maine, they were used more extensively, particularly for crude oil. This was also the case further south, in the greater Boston harbor.
