Abstract
Lure fishing and fly-fishing have been positioned as sports deliberately different from the traditional Japanese
fishing-style. In the case of fly-fishing, casting is the element which anglers must master to cast a fly, done so by using the weight of a line. This study uses experimental and computational analysis to investigate the dynamic behavior of a fly line. Fly-fishing is constituted by various elements, but the importance that casting holds is extremely large. Flying speed, the casting process, and the loop shape of the line while in flight are important for the proper presentation of flies. In the previous research, experiments and simulations were conducted to validate the adequacy of analytical modeling. However, there has been no application to casting devices for positioning lightweight fly. In this study, a fly-casting device that imitates a human arm is constructed using stepping motors. The device is verified whether fly casting is possible.
