Claim:
A portable work platform support system for use on a boat having deck and a railing, comprising: a substantially horizontal platform having a top surface and a bottom surface and a first end and a second end; a substantially horizontal base member having a top surface and a bottom surface and a first end and a second end and comprising: 1) an elongated hollow outer tube of substantially uniform cross section throughout its length having proximal and distal ends and an inner surface defining a cavity; 2) an elongated hollow inner tube adapted to fit into said cavity having proximal and distal ends, the distal end being slideably received in said cavity through said proximal end of said outer tube; a first ground engaging support means attached to the first end of said base member and being substantially perpendicular to said base member; a second ground engaging support means removably attached to the second end of said base member and being substantially perpendicular to said base member, wherein said second ground engaging support means has a top surface and a bottom surface; a first substantially vertical leg extending between said platform and the the first end of said base member and hingedly attached to said base member, wherein said first leg comprises a substantially vertically elongated hollow outer tube of substantially uniform cross section throughout its length having proximal and distal ends and having an inner surface defining a cavity of generally rectangular cross section, and a substantially vertical elongated hollow inner tube having proximal and distal ends, the distal end being slideably received in said cavity through said proximal end of said outer tube; a ladder means on said first leg including a plurality of spaced apart, substantially parallel steps; a second leg hingedly attached to the bottom surface of said substantially horizontal platform proximate to the first leg and hingedly attached to the top surface of the second ground engaging support means, wherein said second leg comprises an elongated hollow outer tube of substantially uniform cross section throughout its length having proximal and distal ends and having inner surfaces defining a cavity, and an elongated hollow inner tube having proximal and distal ends, the distal end being slideably received in said cavity through said proximal end of said outer tube; and a slideably extendable railing engaging support member extending from the second end of said substantially horizontal platform, said support being adapted to attach to the top of a boat railing.
