Blackstone tells us that “Jetsam is where goods are cast into the sea, and there sink and remain under water,” and “flotsam is where they continue swimming on the surface of the waves.” But there is a third category that the law recognizes, though one that (in my experience) hasn’t made its way into the vernacular the way that flotsam and jetsam have. What’s that category? No fair peeking.
I should note that all three terms are described by Blackstone as “barbarous and uncouth,” for whatever that’s worth.
