A subsequent investigation found that the nearby lightship—which was used to navigate the channel at night—was from its assigned location, and there were several uncharted rocks in the area of the accident. Therefore, the investigation concluded that the ship's command staff was not at fault in the accident. The investigators also recommended design changes to the s, then still being designed, namely the adoption of a torpedo bulkhead to improve resistance to underwater damage. The changes would not be incorporated in a German battleship until the subsequent dreadnought battleships, as their increased size allowed room for the bulkhead and associated watertight compartments.
