Nessie fans are queuing up to watch the latest video of a possible Loch Ness Monster sighting.
But locals are dismissing the footage of the five-humped figure as an “optical illusion” caused by waves left behind by a passing boat.
Holidaymaker Tony Bligh, of Dublin, captured the short film while visiting the loch for the first time on Wednesday.
He posted the video on YouTube and it has already racked up more than 22,000 views.
Tony said: “While visiting Loch Ness I noticed this weird formation on the loch near the Inverness end. [I thought] could it be the elusive Nessie?”
In the video there appear to be four to five humps, about 6ft apart, which move in unison – but Tony did concede there was a boat about 1200ft away.
Tony said of the figure: “It was quite long.
“The humps were consistently the same length apart. I don’t know what it was. It was very unusual.
“I am tending towards the wake of a boat – I am an engineer and I am on the side of logic.”
And locals, including respected long-time Nessie investigator Adrian Shine, have rubbished claims the video shows the elusive Nessie.
Adrian, of the Loch Ness Project said it was instead an optical illusion created by the wake of a boat.
He said: “It is a particularly good example of the effect that a reasonably high boat wake can make.
“It shows how powerful this illusion could be. It produces a line of very solid looking humps.”
The video was shot from the Wellington layby on the A82 overlooking the famous loch.
