Where was the cog invented?
Cogs are first mentioned in 948 AD, in Muiden near Amsterdam. These early cogs were influenced by the Norse Knarr, which was the main trade vessel in northern Europe at the time, and probably used a steering oar, as there is nothing to suggest a stern rudder in northern Europe until about 1240.
