Tim Dinsdale borrowed a movie camera from believer turned sceptic Maurice Burton. Dinsdale can be seen on the right of the picture below which also shows Dr Rines, left, and Marty Klein, centre, lowering a side-scan sonar towfish ... possibly the actual one which located the Wellington bomber aeroplane in Loch Ness. Notice the LNI letters stencilled on the boat, referring to the later name of "Loch Ness Investigation".
Close to the end of his first visit to the loch in 1960, Tim saw a dark hump in the water and viewed it through binoculars. It appeared to have a mahogany coloured patch on the side and then started to move across the loch.
Tim filmed the object in long bursts, stopping to rewind the clockwork mechanism as necessary, then the object appeared to submerge and move parallel to the far shore throwing up a huge wake.
When the film was examined the hump appeared dark and some have claimed that a paddle action can be seen in the sequence where the object moved parallel to the shore.
The film was shown on the Panorama programme in the early sixties and provided the final impetus for the formation of the Loch Ness Phenomenon Investigation Bureau set up by Richard Fitter, (Sir) Peter Scott, Constance Whyte and David James M.P.
In 1966 the film was examined by the Royal Air Force's Joint Air Reconnaissance Intelligence Centre who made estimates of the size of the object and also stated that it was "probably animate".
In 1984 Adrian Shine, leader of the Loch Ness (and Morar) Project, and Ricky Gardiner, the chairman of the evidence sub-committee, were having dinner with the Webmaster. The subject of Dinsdale's film came up and Ricky particularly wanted to look at it more carefully, but had always been refused access by Tim.
The Webmaster had a poor quality U.S. documentary which contained a section of the film, pirated, we think, from a copy made by Disney in the seventies and we watched this on the TV.
The TV set had the contrast turned up too high and, in the sequence showing the object moving parallel to the shore, a man could clearly be seen sitting in the back of a light coloured boat. The Dinsdale film was exposed as a mistake.
For various reasons involving friendship and respect for the unwell Dinsdale this was not made public until after Tim's premature death.
Wendy Dinsdale still refuses to allow the film to be properly examined by the Loch Ness Project's evidence analysts which is both sad and implies that there may be something to hide.
It is often pointed out that the Royal Air Force's Joint Air Reconnaissance Intelligence Centre did not spot a boat and said that the object was alive. In fact they said that it was "probably animate" which is not the same thing. The size and speed of the object is consistent with local fishing boats with outboards and JARIC were experienced with aerial film of objects from above, not objects a mere mile away at an angle to the horizontal of only 3o or less.
If Wendy Dinsdale would allow the film to be re-examined by JARIC I am certain it would be shown to be a boat, but, of course, that examination is not being allowed.
Hopefully this situation will eventually be resolved. If the film is genuine there is no possible reason not to allow the examination. In the meantime we cannot show the film to you here and the stills had been carefully selected by Tim and do not show the man at all. I like to think that this was not a deliberate action, but the ongoing attitude to preventing examination does add a little intrigue to the event.
POST SCRIPT: I will need to re-write this section as the film has now been re-examined by one of the same JARIC team who examined it originally. Once Adrian Shine pointed out the man in the boat a detailed examination was carried out and the official opinion today is that the object filmed is entirely consistent with a small boat.
I was recently challenged about the object obviously not being a boat because it submerged as it approached the far side of the loch. In fact this can be shown to not be the case. This image contains a dark band running up the left hand side of the object. This band is the same shade of grey as the object itself.
Note how it vanishes at the top showing that the object did not submerge, but was just lost in the greys of the darker water. I hope that puts that particular argument to rest. Naked Science's methods used on the sequence parallel to the shore adequately put that to bed too.
