Whoa... I had no idea that submarine software was this bad. Not just the lack of warnings but also "Waits for VMS to load the next screen, which can take minutes.". Why do you have to wait minutes to load a map?? And why is this running Windows XP?
I'm also surprised there's no contour lines between the depths (although perhaps this is done to not infer a knowledge of depths in the intermediate points where perhaps there is no such knowledge).
