Abstract

One end of a leg of a boat ladder is swivably and pivotably affixed to the side of a boat and the corresponding end of the other leg of the ladder is releasably latched or hooked to one of a pair of brackets located on the same side of the boat forward and aft of the affixed attachment. The ladder is stored in a vertically upright position with the second leg latched onto one of the pair of brackets. To be put to use the second leg first is unhooked from the bracket and swung outward in a generally horizontal arc of about 180 degrees until it reaches the other of the pair of brackets and is then latched or hooked onto the other of the pair of brackets and then the ladder is swung vertically outward and downward toward or into the water. Standoffs may be provided on each leg of the ladder to support the ladder against and away from the side of the boat or the "logs" or floats of a pontoon boat.
