Toys for boys. Old boys use computers, small boys need other toys. Waiting on Santos anchorage 4 I saw huge NorSul barge pushed by small tug. Barge with hull shaped like a ship, with hatches 4-5m above deck, probably without covers. These type barges are used to transport wood logs. Maybe this one transport logs from Amazona's forest. Ocean going ships can go up to Manaus. Here is my log transport unit - barge + tug. Both based on adjustable icebreaker bow module. Barge can be pushed or pulled from stern (fits bow and stern of compatible tug) or towed from bow. If You want it working alone, there is place to mount twin propeller. No detailed ballast tanks etc, but this You can do yourself. Tug is 120x25, barge segment 50x50, so the best will be scale it twice. Coded in Template Shapes_Text //https://www.thingiverse.com/thing:4863092 presentation of shapes and transformations in csv mode (OpenSCAD CSV) Code included as well as new version of transformation and shapes modules. new linear shape-51 (arc up to 180) used in the code. Probably it will replace shape-11(half of cylinder) and shape-21(quarter of cylinder) as more flexible. As natural consequence of creating this shape comes new rotate shape-30(segment of sphere). Intended to use up to 180 degrees, but with angle over 180 we can get some useful shapes. To use it, You have to declare new shapes in modules lins and rots of Template Enjoy!
