> (for example as result of Ever Given I learned plenty of things about container shipping,
One thing I learned from poking around financial models (I was/am a maintainer for a domain-specific financial modeling language used by a Fortune 500 financial services company) is that some ships are capesize[0], meaning they're too big for either the Panama or Suez canal and must transit Cape Horn and/or Cape Agulhas.
In our language, Booleans are represented as IEEE-754 double-precision floating point numbers (0.0 is False, everything else is true, with the constant True being 1.0), so for a bit I was imagining gigantic container ships dressing up as superheroes and putting on capes, and going to parties out in the middle of the ocean. Digging a bit deeper, I discovered this particular field was being used as a Boolean, and a quick web search ruined the magic of what capesize really meant.
I presume this wound up in our financial models because whether a ship is capesize affects its value, which affects the value of corporate bonds (or other corporate debt instruments) partially backed by ships as collateral. I suppose it's also possible that at some point we entered into bespoke repurchase agreements involving ships. (To avoid various risks in bankruptcy courts, sometimes financing is arranged by selling some asset below market value with an agreement to buy it back at a fixed date at a fixed higher price. There might also be a rental agreement involved. The cash flows look like a secured loan, but in case the loan can't be repaid, a court order isn't necessary to seize assets... the collateral assets have already legally changed hands.)
