Yhat's probably something I was taught in my sophomore NROTC classes and failed to to remember. (O, the arrogance of being 19 & Knowing All There Is To Know.)
Now, I'd wager that there was, in the early days of perfecting UnRep (our acronym for Underway Replenishment) and officer named Burton who cobbled up a system which was more flexible than the fixed span-wire method.
But, now that I have written this, I'm wondering if it comes from the way one rigs a cargo hook from two cargo booms (which uses the hoist winches on both booms. Which may mean I need to dig through old copies of Knight's and the Bluejacket Manual (I've copies of the former going back to the 13th ed of the former; and 1939 edition of the latter).
