THE OERTZ FLYING BOATS
"Among the most successful, and, therefore, most noteworthy, flying boats, are those designed by D. Ing. Max Oertz, which were built at the Oertz Works at Hamburg. Dr. Oertz, the famous yacht and motorboat builder, was one of the first in Germany to realise the possibilities of flying and the suitability of his works, with their special facilities and trained workmen specialists, for the requirements of aircraft construction. Above all, the Oertz Works were not laid out as quantity production works, but were used to meet the special requirements of yacht construction by scientific investigation into the smallest mechanical details, and to devote an absolutely loving care to workmanship and finish.
"These fundamental facts, which were reflected in all new productions of this scientifically working factory, whether boats or flying machines, could already be noticed in the very first machine built in 1910. This was a land machine, a monoplane with monocoque body, which weighed only 770 lbs., and, fitted with a 70 h.p. Gnome engine, reached a speed of 80 m.p.h. This first success encouraged Oertz to return to his proper element, the sea, and to apply the same principles to the construction of a flying boat; this was ordered by the Navy in the spring of 1913.
