Here is a good tip for you if you want to grind German subs: stick to the first U-Boat if possible. This is one of those times when the previous ship is better than the next ship. And here is why:

U Type 1: around 16.5knot top speed fully loaded

U Type 2: 11 knots

Type 1: 4 tubes forward and 2 rear

Type 2: 3 tubes forward

Type 1: About 40+ torpedoes (for my set up, around 30-36 foward)

Type 2: Good luck carrying more than 15

Type 1: Has a deck gun

Type 2: Has no deck gun

I think you can see where I'm going here.
