ABSTRACT:
A davit arm system includes a base that supports a davit arm and engages an underlying ground surface. The system components are preferably designed for arrangement in alternative ways to accommodate different installation environments, and/or for packaging in a bag that may be carried by a single person. The relative positions of the components are preferably adjustable relative to the base to further accommodate different applications. Yet another desirable option is to mount the davit arm on the support base in a manner that allows rotation about both a vertical axis and a horizontal axis. A winch is preferably mounted on the davit arm in a manner that counterbalances the davit arm relative to its vertical axis of rotation.
