Once they get knocked down, do they stay down ?

I used to race on a Ultra Light Sport Boat that was like that. You'd
be sitting there on the rail, thinking about going out on the keel,
saying to yourself: "It should pop back up any second now." After you
said that 4 or 5 times, and rejected the notion of going out on the
keel, it would in fact pop back up.
