I'm playing with GWX 2.1 and I'm navigating in bad weather for 10 days with heavy clouds, heavy rain, zero visibility (1 km), simple navigating

, I can't see s**t. I'm so frustraded because I haven't spent any torpedoe yet, I have a full storage. What the kaleuns did in real life with so many days of bad weather? They returned to base? I'm not very good in intercepting ships only with sonar
