 The Berkshire No. 7 is a small wood and steel canal barge that measures 104 feet (32 m) long with a 20 feet (6.1 m) beam. The depth of the hold is listed at 10 feet (3.0 m) and it had a listed capacity of 216 tons. It is a transitional canal barge with steel framing and wood planking over the skeleton. Clouette describes the hull as being "nearly rectangular in profile, section and plan, with squared-off stern and bluntly rounded bow. Low bulwarks with scuppers rise slightly to a peak where they join the prominently projecting stem". The superstructure is primarily of a single low coaming with convex hatch covers that runs almost the full length of the shop. A rectangular cabin rises up above the coaming and has a companionway in the rear. The Berkshire No. 7 is listed in the U.S. Registry as # 172071.
