I thought this thread was called " A Picture Paints a Thousand Words" .... Can it be again please? Also I would rather it was not locked, unless there is avery good reason.

Many thanks,

Neil

Also, Mike, I think a page seems to have gone on the 'Fin' debate in the revamp; I was about to refer to it in some new thoughts but couldn't find it
---------- and couldn't quite remember what I said (sadly, an experience which is becoming all the more common the further I leave 60 behind!).

During the long drawn out 66/67 attempt, DMC also went for the world waterborne scooter record... here is Don returning to the jetty after the unsuccessful attempt. The scooter ran out of fuel on the way to the measured Kilo... and Louis Goosens had to rush to the rescue to refuel the craft... after that conditions were never the same again, and DMC returned to the WSR to drum up support for a future attempt.... (PS. This message is a day and a half late ;) )

Examining photo's of K7 at various stages of development and operation during it's 12 years of life never ceases to reveal some small detail which may not have received the emphasis in the many retrospective analyses performed on such images.

A case in hand is the illuminating but equally harrowing final photo' before K7 lifts-off (see below), it's brief and uncontrolled flight presaging ultimate catastrophe. The raised starboard sponson, it's stabilising fin well clear of the surface would provide evidence for the well-established view that 'tramping' effects were a major contributor further underpinned by the elegant mathematical analysis performed by Ken Norris to confirm it's adverse effect on stability.

The eye is drawn to this dominant aspect like a magnet ----------- but to the neglect of other features??

Look to the rear of BB below the transom. The rear planing shoe is also clear of the surface and the starboard stabilising fin is only partially submerged. The latter was an addition instigated by Norris in the mod's of early '66 to prepare for the final assault on '300'! It's function was twofold; to aid directional stability and - more importantly - to introduce an additional force component (moment) to help stop the bows lifting.

Now on an ideal surface it would be fully submerged and hence produce it's theoretical restoring force. But on a rough surface with concomitant pitching and rolling it's effect would be much diminished.

Yet another factor to 'throw into the pot' on the 'why's' and 'how's' ----------------!

Have a Nice Easter!

Not surprising really. Coniston in December / January is bloody freezing in my experience!
