U-9 & U-39 tonnage includes trawlers not cargo ships whereas U-20's six are full size cargo vessels of higher tonnage. U-9 had also previously sunk four cruisers for 43,350 tons- HMS's Aboukir, Cressy, Hogue all 12,000 tons; and HMS Hogue for 7,350 tons.

Yes. No warship goes anywhere without orders to do so. Generally, if I understand your question, The German navy completely, outclassed on the surface at sea world wide, confined its operations to a 'war zone' and assigned U-boats either singly or in flotillas to operate in those declared war zones.; primarily along known trade/shipping routes. The proclaimed war zone as of 2/4/1915:and expanded as declared 2/1/17:

Whoops! Some confusion. The German Naval Grid Reference was a system for referencing the a location on a map. Introduced initially by the German Luftwaffe just before World War II, it was used widely in the German armed forces until 1943. Each armed force had its own version of this reference. In the Kriegsmarine version, the entire globe was divided into large square sectors, each with its unique two-letter designation (e.g. AE, AF, BA, BB, etc.). Each such sector was further sub-divided into a 3 x 3 matrix, so that there were nine squares. Each of the nine squares were again divided into nine smaller squares. This map grid system was not in use in WWI. The lines in the warzone maps in the post above are simply Latitude and longitude navigation lines of standard marine cartography(map reading).
