Wave Skipper

Your mention of the miscalculated dive seems very realistic - as I recall reading how Donitz when he was a WWI skipper on a u-boat actually upended his u-boat in an almost vertical angle! Dive control was not really improved until after WWI. I also like the idea of the smarter merchant AIs. I have always hated the fact that in the SH games the poor ship - even though you may be sitting on the surface in front of it - sails steadily into my crosshairs with only meager zigzags. There were cases in WWII when most of a convoy would split up and the ships would run off in many directions if many of its members had been sunk. Those merchant captains weren't a bunch of morons. They wanted to live.
