Hunting In Bad Weather

[Aldag]

I'm out on my first patrol on GWX 2.0 and currently cruising around the Western Approaches, just had my first run in with GWX's DD intelligence and just about survived.

Then i picked up a lone merchant and tracked it using the hydrophone. My problem is that the weather is so poor, and the seas so rough, i can only see it on the scope at a range of about 300m... Which isn't much use for firing upon it. I'm a pretty new player so i've been using the weapons officer to give me firing solutions, but he only seems willing to do so for stuff i have a visual on (the mutinous cur!)... So, any tips on getting a decent firing solution in those sort of conditions?

Thanks in advance
