ABSTRACT:
A collapsible retriever ladder generally includes a first platform, a second platform, supporting arms and a clamping mechanism. The first platform is pivotally attached to the supporting arms so that the first platform can be closed. The second platform is pivotally attached to the first platform so that the second platform can fold over the first platform so as to be sandwiched between the first platform and the supporting arms when the first platform is closed. The clamping mechanism secures the ladder to the upper edge of a side of a boat and is pivotally attached to the supporting arms so that the supporting arms having the first and second platforms secured thereto can rotate inwardly of the boat for storage and outwardly of the boat for use.
