Single best Mod for SH5?

[Onkel Neal]

To ensure it is not overlooked, p-medved asked:

I am completely new to Silent Hunter 5, and I am not very computer savy, as some of the younger players are. To start I would like to know what is the single best mod download; that is simple and safe for a beginner. I would like kind of a step by step instruction, at least for the very first one. I need how to open the downloaded file, and how to put it the proper Silent Hunter file. I would like to know things like how to get torpedos without having to return to port, and ect. Thanks for any help that can be provided.

Your feedback is appreciated, what say ye?
