NYGM and GW - Ship Damage FAQ

I recently had the experience in a Type II of firing one torpedo at a small merchant-1800 tons or so, and waiting 12 hours for him to sink. I didn't fire a second, just let him be. Later I fired two eels each at two similar ships-one of them sank.

I know you need to aim at different parts of the ship, but occassionally even that doesn't work.
