Abstract:
1. A davit system, comprising: an elongate base having a hollow interior and an open top; said elongate base including a straight part and an angled part that is angled downwardly relative to said straight part at a predetermined angle; an elongate boom arm slideably disposed in said hollow interior of said elongate base; an elongate screw rotatably mounted within the hollow interior of said elongate base; a screw follower mounted to a trailing end of said elongate boom arm; said screw follower being in screw-threaded engagement with said elongate screw so that rotation of said elongate screw in a first direction effects travel of said screw follower and hence of said elongate boom arm in a first direction relative to said elongate base and so that rotation of said elongate screw in a second direction opposite to said first direction effects travel of said screw follower and hence of said elongate boom arm in a second direction opposite to said first direction relative to said elongate base; said elongate boom arm being fully retracted within said hollow interior of said elongate base when said elongate screw has been rotated in said first direction a predetermined number of times; said elongate boom arm being fully extended from said hollow interior of said elongate base when said elongate screw has been rotated in said second direction a predetermined number of times; said elongate boom arm being downwardly angled at said predetermined angle when said elongate boom arm is in said fully extended position.
