I've won a bet a few quarters ago. I was on my way back to Wilhelmshaven with no torpedoes left but with some deck gun ammo. When approaching GB from the West side I said to my comrade: you'll see, I'll meet some freighters, but the seas will be too heavy to use the deck gun, but the very moment I reach Helgoland, the weather will become good. We bet.
And I won.
EDIT: Forrgot to mention the tonnage: 96.9k tonns. Would be enough to sink one more medium ship to beat the magic 100k barrier. Thus the bet.
