This reminds me too well of a training course I was on a while back in the Canary Is.
We were practicing coming alongside a dock
and I was very keen to show that I knew the drill (don't remember there being any ladies on board).
Standing at the centre cleat, dock
line in hand, I waited until the gap was about 8 feet and went to step over the guard wires intending to hold onto the shroud
until the very last moment then step off like a pro.
Hadn't bargained for the fact that my foot was hooked up in the jackline, so I ended up folded backwards over the guard wires suspended on the wire by the back of my knees with my head
between the topsides and the closing dock.
Amazing how much strength you can find in such a situation, I managed to pull myself up enough to get my foot clear then fell bodily on to the dock.
I still have occasional trouble where my 200lbs bulk was brought to bear like a cheesewire on the back of my knees.
Moral : If you are going to step off, make absolutely sure your way is clear and you can't trip over anything
