Sadly, there is also the opposite in GWX, even when using Realistic Sinking Times. For example:
H.M.S .Aquatania (45,000 GRT) goes down with either a few rounds from the deck gun or a single eel.
Most Ocean Liners (24,400 GRT) go down with a single eel (either instantly or shortly thereafter).
Great ways to rack up high tonnage counts, but definitely not realistic.
