Yes, Casey is right. If you want the bare bones, just go with GWX and SH3. SH3 is a stand alone program that makes playing the game a lot more fun. GWX (and other megamods, GWX isn't the only one, but the most well Known) is an actual mod that changes the game into what it should have been when released by Ubi. Check the downloads section for links to both.

But you have to remember, There were only a handful of German warships of the size your are talking, and maybe a couple dozen British. You do see more carriers in later years. You can go whole careers with never seeing a ship over 10k tons. Then you will have patrols when you just don't have enough torpedoes available to sink all the large ships you see (Forgot who it was during the war, someobody will know, but he had one of the RN carriers lined up in a perfect solution, alone with no escorts, and had no torpedoes left). So even with the mod upgrades, you may not see an increase in ship traffic. Even though, with the mods, it has been increased, it's big ocean, and you're a tiny little boat.
