Another Stupid Newbie Question

And the next thing is to ignore those lines completely as they are untrustworthy. As has been said, the prevailing conditions change the ranges and can catch you out. If it's daylight at all I submerge the moment we spot someone, as I've been shelled to pieces before by ships I had only just detected myself. That's pre-radar as well.

And that's in keeping with the Sub Commander's Handbook, which is a darn sight less reading than the GWX manual

Poor weather conditions can affect visibility such that at times you can't see anything until your 500m or closer to it. Visibility goes both ways, if you can't see them they (generally speaking) aren't able to see you. In heavy storms you could have a task force go by you 2000m off either side of you boat in parallel and unless you submerge you would never be able to see them (nor they you).
