Let me just get this one out of the way before moving onto the next thing. It was filmed on the 1st of June by tourist, Tony Bligh, and can be viewed on YouTube (as embedded here). The story can be read here. I agree with Adrian Shine that this is no more than a boat wake.
When a report mentions four or five humps in a row, that normally makes me suspicious. Unless there are reasons to think otherwise, it is probably a boat wake. In fact, this is a phenomenon that has been around since the early days of Nessie. I posted an article from 1934 recently which showed the very same thing from the 1934 Mountain Expedition and I reproduce that picture below.
That theme continued into the heady 1960s with the Jessica Tait photograph which even merited a cover on a Nessie publication of the time (below). The Loch Ness Investigation Bureau advised against this being presented as a photo of the Loch Ness Monster, knowing what it was.
Now, circumstances alter cases. When an eight hump sighting is reported, I would be intially sceptical. For example, Mr. U. W. Goodbody on the 30th December 1933, about two miles east of Fort Augustus. Rupert T. Gould interviewed him for his 1934 book and the sketches below are from that book.
We have our excessively long line of humps, but then something unusual happens, they go off on a turn. Most unlike a boat wake. Well, there is something to think about.
