Abstract: A rear access step configuration for pontoon boats is provided. The hollow cylindrical hulls of the boat are modified to form a slightly forward slanting truncated end at the rear of the boat. Steps are formed at the rear end and internally of one of the cylinder hulls to allow a person in the water to climb directly onto the boat at the rear end thereof. A pivotable step is positioned at the rear bottom edge of the step configuration to assist a person in the water to mount the hull end. It can be retracted up and out of position when not in use to avoid drag and spray when the boat is on motion. Hand rails are also provided along the step configuration with a slight forward slant to aid a person in climbing on the boat.
