The advantages of this new machine are to improve the efficiency and to cut down the cost of operation of the ocean long-line fishing vessel which is usually operated manually. In addition , the machine can prevent the large amount of death of sea-birds due to their catching baits. Most of all, the machine is much less expensive than the current imported hydraulic or mechanical type machine. This thesis includes three parts : First, theories of bait- casting machine are summarized and applied to its design and practical construction, which consists of an electrical controller, a pneumatic system and a baited launcher. Secondly, some characteristics of the present developed bait-casting machine have been investigated and analyzed by sea trials, including the effects of torque and speed due to the motor responses via the tank supplied pressure. Finally, an optimal design is obtained according to the comparison between experimental data and computer simulation.
