This could be a JMN boggler of massive proportions!  It's genuine real world, but included with a flotilla of reasonably believable whiffed  ships it could be "interesting"

The Lucy Ashtray (Lucy Ashton) was famous for this, my dad talked about her regularly - he was a Clyde Steamer expert.

I like that idea.  :thumbsup:

Naturally I'm wondering about a working, large scale R/C model of her, perhaps using electric ducted fans if sailing in a quiet park or using REAL model jets for the 'full sound experience'!

It's be like having a duet of Meteors flying along at sea level.  ;D

Just what size of boating pond are you thinking of Kit?
The currently available "Model" jet engines would require a really BIG vessel, and a similarly BIG area of water to accomodate it.  :rolleyes:

I've seen some very small jet engines in magazines and online, here is one of the smallest, not perfect but it is small  ;D

The Thames?  :wacko:

Remember that I live in sight of the largest river in the UK, and it's a mile wide where I am......  ;D :wacko:

I build RC ships. There are 1/96th and (I think) 1/72nd scale plans, the challenge for DFs on boats is thrust to drag ratio. Iíve seen DF powered airboats using LiPo batteries but of course they have planing hulls. The can also be made to work on hovercraft too.
There are restrictions on the use of jet turbines in cities 😉.

Iíve given this some thought in the past 😂

Now that's the first time I've seen "largest" applied to the description of a river ? Now given the Thames is the longest. do you mean the largest volume of water ? Just interested.

It isn't, the Severn is the longest at 220 miles, albeit some of it goes through Wales, but it's all in the UK, at the moment anyway.

The Thames is 215 miles long, and is the longest river entirely in England.

Ooops, yup I should have remembered that  :banghead:

Mind you I've seen some interesting discussions on how much of a river's estuary should be included in any measurement which can change things considerably.

I think the Severn is counted as far as the New Severn Bridge (or the Second Severn Crossing as they call it officially  :banghead:)

Whether they counted it as far as that BEFORE they built the new bridge I'm not sure, but it's only another 3.5 miles down river from the Old Severn Bridge.

I was always told that the Thames is measured down to Tilbury, but to be honest I've no idea if that was true or not. I just trusted Mr Hobdale our geography master  ;)

The River Thames is considered to end at the Nore Sandbank in the middle of the Estuary where the Thames meets the North Sea. That's the official position of the Port of London Authority.

Why your Mr Hobdale thought it was Tilbury is another matter altogether. :rolleyes:

I went to Hartlepool to see HMS Trincomalee, next to her is the former Humber paddle steamer Wingfield Castle. Bit of work and she'd be ready for jet power! Might need a pair of RB199s to make her move though.

Nah, don't stint on the project, go for a pair of RB211s!  ;D

He was a rather strange bloke, must of been due to him being a Yorkshireman  ;D Lucky we weren't asked the question in "O" Level Geography then (Grade A by the way  ;) )
