Ah, the Han Solo fallacy, in which a claim of prowess in some endeavor is rendered meaningless by the mistaken belief that a unit indicating distance is actually a unit indicating time.
BTW I would have to assume that dressing one's self in armor at 60 fathoms would be an even more remarkable feat than doing so at 45 fathoms, provided either achievement were even remotely possible.
In other words, I win.
