The spread of ocean over the vast area has led to the development of the sailing boats. The sailing boats are used for making measurements over the sea surface for exploring the sea bed, marine environment, marine habitats, etc. The sailing boats also prove advantageous for navigational research and for measurements over the surface of the ocean. The sailing boats mostly are self-operated and perform evaluation of the sea bed and surface using sensors. An idea presented has been with a sailing boat which on activation detects the presence of an unknown object over the surface of the sea. The IR sensor measures the distance of an unidentified object and the metal detector helps in detecting whether the object is a metal. The GSM and GPS are used to alert and notify the location of the unidentified object detected. The movement of the boat is controlled using the DTMF. With the use of DTMF we can control the movement of the boat even from a remote location.
