Abstract: Ladders for the transoms of boats having stern platforms thereon include a fixed upper unit and a pivoted lower unit. The upper unit has a pair of tubular brackets fastened to the stern platform with portions that depend below the platform. The lower unit has a tubular member formed with a central section and two integral, parallel and identical end sections. The end sections are spaced apart approximately the distance between the upper unit brackets and planking extends between them forming one or more steps. The end sections of the lower unit are hinged to the upper unit brackets so the lower unit may be moved between a raised position where the step is positioned above a stern platform and a lowered position where the step or steps are positioned below and astern of the platform. In one embodiment, the upper unit has posts that serve to engage legs of the end sections when the lower unit is in the lowered position to limit its downward movement.

Abstract: Improved ladders for attachment to the transoms of boats comprise a platform section that includes horizontal planking and depending tubular frame members and a ladder step section pivoted on the tubular frame members below the planking for movement between a retracted position wherein the step is raised above the planking inboard of the rear end of the platform and an extended position wherein the step is lowered below and aft of the planking. The step is structured so as to limit the extent it will lower below the planking. The new ladder design enables the platform to be free of any elements, such as brackets, etc., and for the step to be aft of the boat's propeller, rudder, etc. When the step is in the extended position to eliminate possible snagging of gear worn by the ladder user or other interference to the user of the free use of the full area of the platform or of the ladder.
