Well no it probably isn't as Nessie would probably react differently to a boat riding by. Wouldn't You think? So more than likely it's just a log or something or maybe that submarine from the famous 1960's picture is back. Probably something to excite the tourist with. Funny how the Loch Ness Monster always seems to hold the same position on the water in every picture ever taken. Personally I think it is a pretty nice video of Loch Ness myself.
