A ladder which is particularly useful as a boat ladder is constructed with a pair of centrally located side-by-side elongated support members which are movable lengthwise, to a limited degree, with respect to one another. The ladder rungs are pivotally attached to the support members such that when one support member is moved lengthwise the rungs are swung to extend outward from the support members for use as a stepping ladder and swung inward to be in line with the support members to make the ladder compact for storage. The ladder is pivotably engageable with a storage compartment in a boat hull for swinging the ladder downward for use from an opening in the compartment and upward in line with the opening for insertion into the compartment for storage.
