A security system for a floating structure such as a boat, or the like, and which comprises an electro-mechanical apparatus that is sensitive to substantial changes in the position or orientation of the floating structure. A sensor circuit means is employed for sensing unanticipated changes of conditions of the floating structure. A detector circuit means is operatively connected to said sensor circuit means to detect loss of continuity in said sensor circuit means. An alarm means is operated by the detector circuit means. A power supply means, preferably a 12-volt lead-acid storage battery, is connected to the sensor circuit means, the detector means and the alarm means, to provide operating energy for said sensor and detector circuit means and alarm means.
