Well spotted, i looked through my other shots and yes he's leaning against those lights on the roof at the stern, then about a minute after the bridge he's gone. Perhaps through a hatch for aircon inspection.

@ Vokstar. You are right, there is someone standing there and when you blow up a stern view, there appears to be no guard rails or anything just there for personal security if he was to fall, would assume he is crew as there are doors and steps at the back of what I assume is the bridge at the front of all those aircon units.

Not at 35 knots later in the day for sure :)

Was watching her pass under the bridge, what caught my eye is a guy standing on the stern, on top leaning against what I think are the navigation lights. He's partially obscured by the exhaust unfortunately, but if you go full size on the pic you can just about make him out. It's not a place I would want to be standing.
