When the boat was approximately 5 kilometers outside of the bay, I saw some outrigger boats in the middle of the sea. I was holding a Sony D-SLR camera in my hands. I pointed it to one of the boats that was going in parallel direction with the ferry boat and shot the boat several times. The sizes of the photographs which the D-SLR camera created were very large and not suitable for this blog. I had to compress the pictures in Adobe Photoshop software before uploading them to this post.
The motorized outrigger boats were used by fishermen to catch fish from the fishing ground which they had made at certain places at sea. To make a fishing ground, fishermen tie long rope to a drum that has been filled with concrete cement as a weight and throw it into the sea. At the other end of the rope, they tie floats. Below these floats, from the surface of the water down to around thirty or even fifty meters, they tie coconut palm leaves around the rope. During the days and nights thousands of fish like to gather around the leaves. These typical man-made fishing grounds can be seen many islands in tropical region. In West Papua waters, we can easily recognize them if we see bamboo rafts with some coconut leaves on them floating at sea. Sea birds such as terns patrol around such rafts to catch fish.
