An animal perch deterrent device comprise a central axis line which has a plurality of radially extending spokes or spikes integrated with and attached to the line at their base that run along the length of central axis line at equidistantly placed intervals and whose proximal end are affixed thereto so that each spike radiates out and away from the central axis line. The device further comprises a first attachment means for securing the distal end of the central axis line to the stern of a boat and a second attachment means on the proximal end of the axis line that is secured to the lower or base portion of the mast. The outwardly and radially extending spikes are comprised of cable ties integrated with and attached to the line at their base and run along the length of central axis line at approximately equidistantly placed intervals. When the device is employed, the central axis line from which the radially extending spikes extend runs parallel to and slightly above the boom of the sailboat when the sail of the boom is furled.
