I did a bit of shading and made some changes to the original. I also photographed it without using flash, unlike last time. the guy on the back is fishing to pass the time while his brother steers.
The buildings to the left, built on stilts, are a Hopa village. The Hopa people are similar to the Kaklak people in the way they make their living. But culturally they're pretty different. The Hopas, instead of living on houseboats like the Kaklaks, live in homes built on stilts. they have many large communities built in and around many major cities in Lunaku, even a few in rural backwater areas. Most make a living fishing and building boats.
the boat in the foreground is neither Kaklak nor Hopa, however. It is a cargo boat. Transporting goods to other countries is done by modern container ships, but local transporting of goods is still done by old wooden sailboats like this, at least to communities along a major river, canal, or body of water.
In the far background right is Kanaku, Lunaku's largest city.
