Thanks for the interest, those above.
But no one mentioned 1944-1945, did they? Hmmmm..
'MinimumSurface = 100.0 metres squared':
This means that the asdic must contact 100 square-metres of U-boat hull in order to send a contact-ping back to the transmitting warship. If the value is raised to 300 in very shallow waters, then 300 square-metres of U-boat must be contacted (about 17.5 x 17.5 metres.)
The value in GWX = 0.0. Maybe that explains why no GWX user ever makes it to 1944-1945.
Stiebler.
