Remote control unmanned fishing boat and device for remote control thereof

A remote control unmanned fishing boat intended to effect remote control fishing, comprising:

• a depth sounder for measuring the water depth and finding the condition of water bottom;
• a first transmitter for transmitting by a specific radio wave the information obtained by said depth sounder concerning the depth of water and the condition of water bottom;
• a propelling power source for propelling said boat;
• a steering device for steering said boat;
• a setting device for freely detachably mounting a fishing line, said setting device including
• a hook section capable of being freely opened and closed magnetically and moved in the longitudinal direction of said boat,
• an electromagnet for causing said hook section to be opened and closed,
• a light shielding member adapted to be moved in the longitudinal direction of said boat in conjunction with said hook section,
• an irradiating device and a light receiving device so disposed as to be disabled to effect transfer of light prior to the movement of said light shielding member and enabled to effect transfer of light without being intercepted by said light shielding member subsequent to the movement of said light shielding member, and
• a load transmitting device for transmitting a signal based on the impingement of light on said light receiving device;
• and
• a first receiver for receiving specific radio waves concerning the operations of said depth sounder, said propelling power source, said steering device, and said setting device and inducing said operations.
