Amphibian monoplane entered by the builder Strack Flugzeugwerke (Duisburg) into the Bodensee-Wasserflug 1913. The machine had a unique amphibian construction which worked such that the land undercarriage was fixed but the floats could be moved up and down. When landing on the water the floats were set in the down position, so that the fixed land undercarriage cleared the water.
