Loch ness monster close encounter

1971 - Robert Badger claims to have had an straight encounter with Nessie while diving in Loch Ness.
Pretty scary stuff, whether real or misidentification, I had to make an illustration out of it.

"I swam out from the jetty to where the loch bottom falls sharply away to really deep water. I thought that for safety reasons I shouldn't go any further out when an object materialised out of the gloom in front of me.
As I got closer I could see that it was the body of a huge creature moving from my right to my left heading out into the main part of the loch.
I couldn't see the end of the beast but I got close enough to touch its skin which had a rough texture.''
