Jumping a Ferry in movement

[Sparrisen]

I need a danger assessment here. Currently, I've concluded the following:

1: Don't jump in front of the ferry, you will be sucked down underneath it
2: Don't jump on the side of the ferry, because several ferries suck in water from it's side to cool its engine, and anyhow, you will most likely be sucked down underneath it.
3: Don't jump straight down behind the ferry, because you will turned into minced meat. (I don't really know how far out a ferry's propellers go though)

So, that leaves me with an angel of like 45 degrees, out from the corner, behind the ferry, to avoid most of the turbulance, if anything, you should be pushed AWAY from the ferry, and I can't fanthom why you would be sucked down, and AWAY and NOT DOWN, everything else seems acceptable.

I think you could jump behind the ferry too, if the speed of the ferry and the point you jump from are high enough.
