How the fishermen of Xiamen get back and forth from their boats.
This is a video that shows the crude rafts that fishermen in Xiamen use to get out to their boats and then back to shore. They are essentially just rectangular pieces of foam, cut to be roughly four feet long and maybe eight or nine inches wide. They are often rigged up with wooden support beams and wrapped in a fishing net to make them easier to handle. The way the fishermen use these rafts is simple: they toss them in the water and jump on. They use a paddle (or something that can be used as a paddle) to row themselves back and forth.
This is the same idea as Mexican fishermen using old beer coolers as dinghies.
