when me and hannah took her springer out last sunday we took it carefully to start with, however hannah did sail her boat across the wake of another boat, her springer submarined as she was going fairly fast at the time and the water was half way up the superstructure for 2/3 seconds, i thought holy sh1t she is a goner but she came back to the surface we brought it back in to check for water inside and it was bone dry. we have got no floatation in it just a light, very close fitting superstructure and coaming which is about 1 inch high.

Or repairing decorating damage  :(



Nearly re-plastered the blown sections of plaster so I can make a start on the springer's superstructure.

Yes, it can be done with a washer pump.. but on 12v... you might want to try it on 6v to see how effective it is or try to find a 6v pump...

That is terrific Toes. Is it yours?  The monitors are nice, custom made? Not much red paint required then  ::)   P.S. Oh yes it is your`s ! Had another look and spotted your trademark distress flag signal again( inverted Union Flag)  :o

In order to reduce submarining tendencies at full chat, how about a wing on the end of the skeg to prevent the stern lifting? If it's fixed, it's not a rudder, and indeed if you used twin rudders it could be a rudder post end support bracket and not a wing at all, oh dear me no.

Here's mine in the style of a British Waterways Bantam tug......

would you believe thats exactly the superstructure I had in mind for mine? 

I'm afraid after seeing the whole "Springer" thing in the main site and seeing the print out side elevations, the idea kept nagging at the back of my mind to make one.  Finally after handing in my DT coursework and having a whole morning of nought to do in the school workshop, I grabbed some wood and built the hull.  Then this morning I kept looking at it and thought, "hmm better make it go".  A quick bit of scrap box raiding and I was able to produce a lot of the hardware needed.  I'm getting an old RC set off a friend for a fiver next week so hopefully I should have a working hull by the end of Wednesday, or not, I suspect the transmitter is a goner  :-\, at least I'll get a reciever and some servos, and I can just use Willits transmitter.  Unfortunately I made mine a little bit too long, more like 19 and a half inches!  Also I only had a 2 bladed prop handy for the prop shaft I used.  And yes before anyone asks, the bow and transom (not to mention a lot of the rest of it) is made out of 2 x 1 softwood.  I'm afraid my school doesn't go in for things like balsa, it was all I could do to get the thin ply for the bottom!  You know I said I did a bit of scrap box raiding?  By that I mean I forcibly removed (hammer) all the fittings from an old piranha boat that really was past it, which is why the prop tube is covered in old epoxy!

This could be the place to put "wings" or plates to stop the ploughing. I get the feeling some folk have forgotten the concept of a tug. If you want to go fast dont build a flat-sided pudding bowl. Or build a top that looks like the sail/conning tower of an Akula and charge full speed till it acts like a submarine on purpose ;D  Hey good start killit, keep us informed when you next raid the parts-bin. BTW , I`d reduce the mass of the rear midship cross-brace if it isnt too late. Knock that one out and replace it with full depth ply same as hull-side to make a water-tight open top box.  Keep weight down low. Are you going to support the prop shaft ?

Morning Arrow5,

You still after a 6v washer pump, apparently some early VW vehicles had 6v electrics. Could try VW specialists for one.

Finally made a start on the Superstructure. Building it my usual way ( making it up as I go along with no drawings ;D) and using 2mm balsa. How's that for keeping the weight low. I have built a Tyne style wheelhouse and will add some photos when I finish building the superstructure. Have also turned the wheelhouse into a big sealed box, Will put the batteries in prior to radio gear and test it's self righting properties ;D

Shame you won't be at Wicksteed with McPuffer.

Clive :)

PS Nice job Willits.  So how many Springers are being built now? And how many will be at Wicksteed?

Any thoughts on Tobyker`s (and my ) idea about extensions on rear end mods, if you know what I mean,skegs, plates etc. or should we just accept the limitations of the design. There is always the throttle control !   Mayhem Weekend....hmmmm, I`ll be there in spirit and waitng a full report here . Take your cameras. Any Scots activity on Springers ? Largs? Buckie?

There was a discussion (on the other 'board') about adding winglets, similar to F1 racing cars under the rear of a Springer to see if it would hold the stern down when at speed and stop the 'diving' tendancies of a Springer. I have been carving wing shapes ready to fit to Tigger, but have yet to try them to see what effect they have. One problem i CAN see though is that the stern 'digs in' when doing reasonable speed turns and a winglet may make the situation worse..  :o

Yes Arrow, the Sun XXVI is mine.. and yes, the Union Jack is inverted..  :P

Its nice to see how many Springers are being built / have been built over there in GB and we (the colonies  ;D) are looking forwards to reports and pics from some of the up and coming meetings..

      Obviously aimed at the export market :o     I hope the winglets ideas all die a natural death...what is the old saying about making a silk purse out of a pig`s ear. I much prefer detailing or imaginative style of craft and fun fun fun. Leave the super-tweaks to the hydroplane guys and F1 types. JMHO.  Tut tut Toes "Union Jack"......only when it is flown on the Jackstaff otherwise Union Flag. Which may be out of date soon in view of the recent parliamentary elections where the Scottish National Party won a majority.  Home rule next ? Independence ?  "FREEDOM" as a famous Aussie film star shouted in a comedy film on the subject.  John Paul Jones should have stayed at home, WE need a navy too.  Hmmmm how did I get here , so far off topic...dont answer that !  Back on topic; Kendal I`m old enough to remember 6 volt systems in cars and vacuum driven winscreen-wipers, even starting handles, handy for winding the car out of a ditch !

Hi Arrow,

I am just old enough to remember the last two and yes the starting handle was great for getting vehicles out of ditches.

Hiya, I'm afraid removing the cross brace is a no no, simply because its rather well glued and pinned into position  :P so any demolition will do damage to the rest of it.  What I'll do is glue a piece of balsa or ply to it to make the thing go down to the bottom of the hull.  I guess it didn't come out in the photos too well.  If you look at the very end of the stern tube there is a bit of balsa that comes up from the bottom cross brace to engage in a notch with the stern tube.  This has rendered the whole thing pretty solid.  I realised I would need it when I first applied power to the motor (an old Monoperm by the way it runs very well), there was an awful lot of vibration from the tube, so I did the fix and its dead quiet now.  Thanks for the info, given me things to think about (like keeping it dry!)

I considered putting a skeg in, but decided that no-one would see the rudder when its in the water!

How about cutting the rear brace just inboard of  the pins to leave two blocks to support your full depth bulkhead,  (ie remove about 80% of the weight.)   Good you supported the prop-tube, couldn't see any in pics, external skeg will help with straight-line tracking I think. Waiting to see your top , some freelance "scale" details perhaps ?  More pics please.  Any more Springers in the pipeline ???????
