I am gathering that there is not much interest in my South America topics so this will be the last one.
Chile has a similar problem to the Scottish Western Isles that led to the development of the Clyde Puffer. Remote communities on islands, poor or non existent roads, lots of islands etc. The difference is scale. The Chilean fjords & islands stretch from Cape Horn in the South to Puerto Montt in the north - a distance of around 1000mls. The scale of the waterways is also very large with very high mountains. The communities island based and widely spaced. There is now a lot of fish farming although the landscape scale is so large it is difficult to see. These often have no overland access at all.
Scotland developed the Clyde Puffer and Chile seems to have these - pictures below. They come in all sorts of sizes, carry just about anything, don't need docks, etc etc etc.
Some of the pictures below were at extreme range & heavily cropped, some were taken in rain & some both. Please excuse the quality issues.
