O.Thetford, P.Gray German Aircraft of the First World War (Putnam)

Oertz W 4
   A series of twelve living-boats was built by the Hamburg Yacht firm of Oertz: FB 3 a pre-war design which bore the Naval number 46, W 4s 63 and 75 of 1914, W 5s 276-280 of 1916, W 6 Flugschoner 281, W 7s 474-475 and W 8 1157.
   All these aircraft featured engines buried in the hull and driving pusher propellers through a system of geared shafts. Dipl. Ing. Max Oertz gave special attention to hull design, providing sufficient beam to give adequate lateral stability on the water with no more than spring-loaded hydrovanes at the wingtips to prevent them submerging. A feature of the earlier machines was that the chord of the lower wing was considerably greater than that of the upper wing; it was also greater in span, with consequent inward rake to the interplane struts. The ailerons were also on the lower wingtips.
