So the operator has the engine off and just waits for a while until the divers seem far enough or deep enough and then starts the motor and puts it in gear?
I've been in a slight chop once or twice, when the captain can properly judge waves and wind he usually has to adjust the boat's position every once in a while. They keep the engines running. On the way in, the briefing was go straight down and meet up at the bottom, captain and DM tell you when to jump, a that point they cut off the props and keep it off until you're under. On the way back the captain drops a rope, everyone hangs on to the end, the captain will wave the next one in when the props are off and it's safe to get to the ladder.
Like you say, "safe" as in "props not spinning" does not mean safe from the platform coming down on top of your head, banging your shins on the steps, falling off, and so on and so forth.
