I found this transcript that Tim Dinsdale had in his book “The Leviathans” ( 1976 ed Futura pub ltd London page 239 ) from a tape of an interview with Mr Macllelan and Mr John Mac Varish who had an encounter with the creature of Loch Morar in 1975.
The fear from the men shows it was something they did not recognise, however that does not mean it was an unknown animal , just unknown to them. Once again the sighting follows the pattern of so many other lake creature sightings throughout the world. the description of a whale like, the size and the movement. One day we may find the answers.
