A device is temporarily attached to one side of the stern of a boat in order to modify the wake pattern of the boat by effectively making one side of the boat longer than the other side. The delayed wave on the opposite side of the boat from the wake shaping device allows the wave to crest over the natural wave on the side where the device is installed. In one example, the device has a frame with a side surface angled outwardly 12 degrees from the side of the boat, a mounting surface with a platform index notch configured to be positioned over a portion of a boat platform. A wedge shape utilizes water pressure to distribute the load evenly across the fastening side of the device, thereby allowing for a tight fit to the back of the boat.
