Abstract
A removable ladder for placement over the side of a boat and extension into water for aiding ingress and egress of swimmers and the like is disclosed and includes a pair of elongated, generally parallel extending upright members terminating at respective first ends in boat engaging hooks with a series of cross members extending generally parallel to one another and spanning the upright members to form a sequence of steps. Each step may comprise a pair of laterally displaced cross members and the boat engaging hooks may be formed as a pair of generally orthogonal projections one extending parallel to and displaced from the direction of upright member elongation while the other extends generally parallel to and displaced from the step forming cross members so that the hooks may be positioned behind upright portions of the boat railing to secure the ladder in place and obviate the need for handrails on the ladder, since the railing upright portions may be used as handgrip regions when using the ladder. A technique for forming such a ladder from hollow aluminum tubing of generally square cross sectional configuration is also disclosed.
