Yes Arrow, this might be interesting.  I have to admit I was toying with the idea of putting a Graupner jet drive in a boat and building up the top like a PBR per your suggestion last summer. It would just be for fun of course.... ;)

I think the problem with the Cat Drive would be cavitation unless the diameter of the tube is large enough. There might be a way to monkey with the nozzle exit diameter to adjust back pressure to keep the prop in clean water... :-\

I was rather taken with the simplicity of the straight shaft at an angle in the bow thruster.

Andy , another possibility could be a half-round channel, not a tube, from front to rear of the Springer hull. Maybe even have a Kort ring section round the prop ?     I saw the Archimedes Screw machine that crossed the Bering Straight in mushy ice and was buoyant on water as well as screwing its way along snow and firm ice. The current air-screws and boat/ship propellers are just a section of that system but for high speed use. Gosh, do we really think there is a better mouse-trap? {-)

I'll answer with a question - How many models of our solar system were formulated before we finally got it right?    Hmmm, hang on a tick...I like IDEA of gravity and all that but, did we get it right? Or is it just what's in vogue?  ;D

As long as we are having fun I don't think there is a wrong answer.  What we Really ought to do is contact Delft University and get one of their young brains to write a thesis on the Springer as a graduation project.  The heck with North Sea supply boats....we need answers!

Anyone speak Dutch? ;)

    Flemish or Walloon ?    You are correct of course, only a matter of time till we crack the gravity problem.  Any fool can see that the sun goes round the earth >:(.  Same with marine architects, they`ll just tell us to put a pointy bow on our Springers. >:(    BTW Any Springers being built in the Netherlands , for fun or diploma?

Toesup boat werks update...

Its a long one, sorry...
You had better remove ALL liquid refreshments and foodstuffs from mouth before reading further, we hold no responsibility for aspirating viewers of this post  ;D

Project Z

No one seemed to notice on my previous posted picture, the Knees (Elbows) are on the wrong end.. Actually, they are on the right end for this Springer from the toesup boat werks..

The toesup boat werks is proud to announce the construction of the worlds first Regnirps class, a backwards Springer.. It is to be of a modern Z Tech type.
Project 'Z' now has a name.... and shall be known as 'Douglas Corrigan'... or 'WW' for short.  O0

Project S

The toesup boat werks design department has been working overtime to overcome the diving tendancies of the Springer.. this time i think we will make use of these 'traits' and use them to our advantage.

The toesup boat werks is proud to release information on its NEW S class Springer...  'S' for Submarine..

So, this is to be a Sub Standard Springer...

Please welcome the SSS Red Oktober...

At this point you are all going to be thinking...   :o :o :o

   ...Hi Guys...

I would say that the brass things are "super reinforced Towing Bollards"...

Looks like they are fixed to the keel & strapped to the wooden uprights with wire....

A Beefy Build Indeed...

  ACH ZO.....VEE HAF VAYS TO ZINK DER OPPOSITION YAH !  A NAUGHTY SUBMARINE SPRINGER  {-)

      if you make a boat thats intended to float and make it submerge , does that mean any torpedoes you make will float ? :D :D

     Methinks a springer corvette ( springette ) with depth charges will be needed. ::)

But i dont have any 'brass thingies'....  :P

I do have Ali tube, bound and epoxied to 1/4" ply bulkheads as towing bitts though...

I HATE hearing the sound of towing bitts being pulled from a deck...  :'(

Model Engineering show at Alexandra Palace, London - see Commercial Events
There was only one Springer in the show, it is mostly a model engineering show after all, on the Blackheath Club stand. They are celebrating their 60th year BTW.

They are flying the Mayhem flag as you can see if the photo works.The card says it was built in 2 weeks for the Mayhem Weekend. I haven't looked back in the thread to see who it was so the owner can own up and post a better picture.

That springer is owned by steamboatphil, search for last years Mayhem Weekend I am pretty sure there is a picture there. Phil is into straight running steam boat of all shapes and sizes, he hopes to make a springer one for this years Mayhem Weekend. Also I took a picture at Warwick last year that should have a thread as well.

Mr Andy , is that a plastic bottom , do you think it will be robust for a head on attack   {-) .
and what about from the under side especialy if our friend from acros the pond Toesuppa gets the submersible version under the water  ??? .
And i agree with boatmadman that bottle is far to close to the edge  :o .

Still the Youngs Winter warmer seems to holding the Steam springer together (strange thing, late at night I appear to be building 3 !!!!!!)

When the glue dries inside, he will be fibreglassing the inside and the outter at a later date, the Newcie was only on the edge for ever such a short length of time. {-)

Andy,

Is the Banana Wine not being used then?

I imagine if you held it together with some of that it would really be a 'Springer'.....yo yo effect and all that!
