Heavy seas affect torpedo performance?

[Gambit]

Hi all, I'm a newbie here. Have learnt a lot from this forum the last few weeks thanks to everybody. I've practiced much manual targeting including the Dick O'Kane constant bearing method which works quite well!

However I have a question. In my current scenario I've a juicy 6 ship convoy coming down in 2 nice rows for a constant bearing shot. However I've tried twice and miss with all 4 bow torpedoes. This hasn't happened to me before. The only difference seems to be the heavy seas (my conning tower pokes out sometimes in the wave troughs).

Finally my question: Does the sea state affect torpedo performance, e.g. at 25ft depth setting do they jump out of the waves and affect accuracy? What can be done if so? I really want to nail this convoy. Thanks.
