every year around now there does seem to be a 'sighting'. Could it be that this is the tourist season in full swing? How cynical of me~~~~
I have not heard the gentleman speaking but he does, as you say, make a living from taking out tourists on the loch.
Just a wee bit of "advertising" perhaps.
I have kayaked the length of Loch Ness and the water is very "peaty" so you cannot see anything even only a few inches down. Most of the sightings seem to be around Urquhart Castle and I can tell you that there is quite a current coming out of the bay so perhaps the 'creature' is nothing more than a tree stump being washed into the Loch itself.
That is the mystery~~
