Matt Boy, it is Indian Navy flag,hoisted astern. But really looks like a person standing )
Kyle, Russian flag is hoisted on top mast, above superstructure.It smaller than national flags, according to standards. But still visible )

Looks to me like a Russian flag that's draped around the staff due to superstructure blocking the wind, though it does do a pretty good job of imitating a person standing in a Naval uniform.
Kind Regards, Kyle

Is that a person in a white uniform standing on the stern rail? For a human being, it looks very tall.

Ah thanks, I had not realised that your shots dates from four years ago.

Thanks, Pieter!
The bridge is Russkiy Bridge, constructed as a part of Vladivostok development for APEC summit held in 2012. The bridge is connecting main land and Russkiy Island. And of course it completed already. It can be seen from other photos taken later on )

Nice shot, but what about the bridge being constructed in the background, looks like a hell of a project.
