Hello Down There

Found the sight while looking for an answer to why my boat in SH IV would no longer reload torpedos after a finished mission. So I ordered the U-Boat missions game. That was working fine. I came back to Subsim web site for some tips to make the game more interesting and watched 5 or 6 of J squared's You Tube videos and marvelled at the graphics and his ineptness at running the boat. With peaked interest I ordered SH V and discovered my own ineptness in that platform. It is entirely different from the others in its handling. Where are my navigation tools? Maybe by the time I finish the "Training Missions" I will have learned a few things.

Which mods are there to help steepen the learning curve?
