A couple of 555 direct drive with the rest of your
set up.
Speed is not an option with springers unless
you go brush less/lipo and maniac speeds.
They tend to nose dive with too much power.
Slow revs and plenty of torque with twin Korts
will make a fine model.

Tugnut, Wow, that looks great pushing that barge!!!


What drive have you got there?
What would you suggest I put in for a single KORT, 150% Springer???

That's awesome Tugnut! Thanks for the info....


What's the pump for? fire nozzle??


So, if I was to build a 150% Springer, maybe a pair of gearboxed 600's with 50-60mm props and Korts would bey strong but not too fast???

Morning all

The current springer was the first boat I built so is carrying all the newbie mistakes I made, the most important being not thinking forward to changing things later. The upper superstructure is very small so I am stuck with fitting everything in the hull (all the electronics, motor and two lead batteries). Gets warm in there plus is a pain to work on due to my big hands not having any space.
I am thinking of a major refit. New superstucture, bigger deck opening kort nossel and different batteries(lighter)

Scrub around my last. Managed to kill the springer this weekend  :((
Went to pick it up to do some maint after her sterling service at the MM and DF65 regatta this weekend as a rescue and mark recovery boat and the darn deck gave way dropping her from about 4 foot onto a concrete floor. All the electronics, batteries etc were ok but the hull is now kindle wood. Scared the cr@p out of the land sharks (my cats )as well .
Currently designing a super springeresk thing. Roughly springer shaped but moving away from the hydrodynamic properties of a brick. Only 16" long but 11" wide it will have two fixed kort nozzles with 60mm props. I am going to name it the Clarkson as it's all about POWWWWWEEEEEEER.
Props, motor and battery with a hull around them.

Too bad for your springer.  <:(

I get your Clarkson thing. I also have a regulation-size springer (but with a brushless motor and a 45mm prop which helps tow 350kg ships). But right now I'm designing a slightly bigger one (around 600m; 1.25x the reg size).


My first springer was just a side project while working on my Odin tug. But I really like my springer ! Funny little thing and with the right prop she's able to tow quite well. And run time is around 4h.



Anyway, I'm going with two 50mm props in steerable korts with brushless motors. Not as wild a prop/size ratio as your project but I'm positive she'll tow well. We have CNC cutting machines at my club's workshop. Still need a quick introduction as how to run them. Then go !

Reading this after a long break I relate to Z750 Jay's experience with dropping his Springer, as mine had a simular experience after prolonged use by two of my Grandsons. The result was a holed and badly delaminated ply hull, having looked at the possible repairs, sheathing with fiberglass etc was quite costly, so I eventually found that 'Models by Design' produced a complete Springer hull for only 20. Having bought this I was able to transfer all the components over and she is now somewhat lighter and fully functioning again as in the pic.
'Models by Design' were great to deal with and only a couple of weeks in producing the hull I can't recommend them enough.
Cheers Chris

 Not a bad price of 50 for the complete kit.
Currently got a Bantum Canal tug as a stand in for the springer. It's tiny - only 14" long but has all the stuff from the springer in it. Also handles like one with lots of submarining at speed.
One of its good points is that it makes the springer hull look roomy in comparison!

 :-))   Hope somebody builds a scale model of this one...it`ll send the rivet counters mad. Imagine the pond-side arguments, "it IS a Springer" >>:-( .   "Nah , nothing like it " <*<  etc etc.   Take this picture with you if you do build one. {-)

Oh oh, might need a repaint soon.    Don't forget the Springeren submarine in the Aalborg Maritime Museum in Denmark.

Further to Ned`s post about the various ships called Springer I Googled the Rhine one and found details. It is an 85m long hopper barge powered by two 450hp diesel Schottel drives. Carries 1500 cu.m. , aprox. 3,135 tons.  It is named after a shoal in the North Sea.

hi guys,
can any-one tell me the size of the little tug on page 31, maid of the mist 2?
I think it is approx. 5M loa ,but i dont know , it is very hard to tell from the photos
it seems small at that size
I am interested in it,as a simple tug ,dont know at what size yet,could be very small , or bigger,approx. 500mm,but its a bit hard to visit from Australia, to find out .
its simple line will lend to a quick built tug
regards and thanks bill S
