The more I play this, the more I like it.

One of the biggest differences is the waves are not as large when the wind reaches 15mps. As a result I have less torpedoes breech the waves under these conditions and am able to successfully hit targets by running the fish at a depth of 4.2m
In other mods I have had torps set at a depth of 6.5m breech. So this mod is actually playable in 15mps winds.
Am going to try out the anti-humming bird mod for this in my next mission.
