I don't know if yo are playing GWX 3.0 with or witout the "16-km-atmosphere-mod". With the "16-km-atmosphere" you'll see a ship at (round about) 800 m, without at 300 m. So it's more easy with this additional GWX-mod. I prefer to sink ships in heavy fog and got no problems - even if i lost sight during the attack.
