As the operator was attempting to back off the sand bar, the injured/desceased subject ran to the back the vessel to equally distribute the weight onboard.  While standing on the seat near the stern and holding on to the stern navigation light, the vessel broke loose from the sand bar, causing a sudden shift of the vessel resulting in the subject breaking the stern light and falling overboard at the stern.  The propeller was turning at a high rate of RPM in reverse direction and drew inward resulting in massive/fatal trauma.
