Q: Will the sea state effect the player's ability to attack a target and will it also have an adverse effect on the torpedo?

A: The weather will definitely affect the player's ability to engage a target. First, bad weather will influence the sensors, making targets harder to find. Second, the sailing performance of the U-boat will be affected, making it harder to reach a good attack position. Third, the crew will get tired faster sailing on surface during bad weather and thus perform poorly. Fourth, torpedoes will miss, detonate prematurely or fail to detonate more often.
