American naval constructor D.W. Taylor discussed qualities of the battle cruisers the British HMS Lion and German SMS Moltke according to the Dutch magazine Marineblad dated 1913-1914 no. 4

The British HMS Lion

The German SMS Moltke

An item referred to the Journal of the Franklin Institute in which naval constructor D.W. Taylor (1) of the US Navy calculated that the German battle cruisers of the Moltke(2)  type and the British Lion type (3) had an insufficient coal bunker capacity with respectively 3.100 and 3.500 tons to retain their hue speed during a battle, Even at a limited speed was the coal consumption already high. The low freeboard aft of the Moltke was a serious problem which became clear when she visited the USA heavily stamped while the aft ship was lying too much upon the water. In the Naval Annual of 1913 wrote admiral Custance (4) that too much of the heavy armament was offered mainly to obtain a higher speed.
