ABSTRACT:
A boat boarding ladder for engagement to the gunwale of a boat includes a U-shaped frame having upstanding legs attached at one end by a bottom rung. A U-shaped support member is pivotally attached to the upper end of the legs of the frame. A bar is attached between the legs of the frame intermediate of the pivotal connection of the support member to the frame and the frame rung. The legs of the support member are curved such that the support member when pivoted against the bar attached across the legs of the frame forms a receiving area between the support member and the frame for attachment of the ladder to the gunwale of a boat. A Y-shaped brace is pivotally attached to the legs of the frame intermediate of the attachment of the support member and the rung to the legs of the frame. A chain is attached between the legs of the frame and the brace member and positions the brace member out of the plane of the frame and against the hull of the boat at an incline relative to the boat.
