Two of the sightings were from the cruise boat Royal Scot and the third was claimed by a fisherman at around 10pm. All were reported in the Fort Augustus area.
The skipper of the Royal Scot, who asked not to be named, spotted a fast-moving wake in the water at around 2pm, but thinks he was the only person aboard to see it at the time. The loch situation at that time was flat calm absolutely mirror glass, he recalled. It was travelling at 30 to 35 miles an hour. It was probably chasing salmon. It is some sort of fish-eating machine.
