extreme waves (size and wavelength)

[Hitman]

Silent Hunter 1 had slower top speeds in bad weather. They omitted this feature in SH3

What? I thought that big waves actually slow down your boat in SH3/4. Are your sure or did you mean something different?

On a side note, I have readed already several accounts explaining how Uboats were able to escape on surface from escorts -even destroyers- by racing ahead flank against the sea. Apparently the thin frontal section of the uboat (Which in fact is not a hull, but a hull-shaped fairing around the steel cylinder of the pressure hull) allows them to run faster against the sea than normal warships, hence they might actually be faster on those conditions than a ship which would normally be faster than them in fair weather. Also, I suspect that running paralell to the sea would be way more dangerous for a destroyer (higher center of gravity) than for an uboat, whose center of gravity is below the waterline. In those conditions, the DD would probably be chicken first and turn away, leaving the pursuit
