ABSTRACT:
A ladder intended for use in boarding small boats has side rails and treads interconnected by integral and precut joint elements designed for ready connection and disconnection. The connected treads and rails are suspended from the deck or side of a boat by crank-like hangers pivotally and releasably secured to the side rails and having grooves enterable by one of the treads. Anchoring members on the hangers engage corresponding fittings permanently secured to the boat to suspend the ladder over the side of the vessel. One of the treads has braces which engage the sloping side of the boat to keep the ladder rails generally vertical.
