Voith Schneider Drive Tug
« on: June 18, 2009, 10:39:43 PM »

Hi Folks

Looked everywhere with no luck so I'm asking the world !!

I would like to build a tug with a single Voith Schneider Drive

The only specification I have is that it must be a minimum of 300sq.ins - yes its for scale steering

I'm prepared to build from scratch if I can find some guide plans

Seen the Sirmar/PPS offering but its a touch small (265sq.ins.), shame cos it looks good value. Can anyone think of a way of ' Stretching  ' it?

Thanks for giving it some thought

Regards

Most models of modern hulls can be used for Voith.
Just check the underwater shape.
Modern tugs are offered with conventional prop drive, Schottle drive or Voith Schneider.

Check on some of these threads..
http://www.modelboatmayhem.co.uk/forum/index.php?topic=11087.0 to build your own drive..  %%

Gatica. Its a scratch build with two Graupner Voith's, but it might give you a few ideas
http://www.rcgroups.com/forums/showthread.php?t=796319&highlight=gatika

Harbour Models (LA, USA) do a single Voith 'kit', though I'm in the process of squeezing in two Voith drives in to one of these hull's

Hi guys,
Thanks for the replies,

Bob. Cant find any plans for flat bottom tugs, which I'm assuming I need for the drive to sit in!

Toesupwa. Build it? I think its a bit late for a degree in engineering  ;)
                The build thread on the Gatica was quite something.
                Harbour models - bit small for my requirements

Hi Longshanks,
 I think you will find virtually all voith units are harbour/esturial work tugs, as the units do not lend well for offshore work and they are too thirsty for fuel on long tows. Some of the bigger units are know are the Admirtalty Twin Unit tractor tugs. I have attached a couple of photo's of one in drydock.

Longshanks,
Old Dodes is nearly right, but he excludes car ferries/passenger ferries.
Almost any hull can be modified to take a VS unit as in its simplest you just cut a round hole in the bottom of your hull.
It isnt necessary to have a flat bottomed hull as the water will surround the blades.
The newer hulls have a large skeg on the aft end to help stop the tug "Skating" across the water.
Strange answer from Dave as he works on a VS ferry!!!!!

Yes, should probably include ferries, research vessels and military ships...

RV Knorr was originally a VSP ship.
http://members.1vsmc.at/fprossegger/index.php?option=com_content&task=view&id=40&Itemid=69

The ferry boat Molengat is twor VSP drives, one at each end.
http://www.nauticexpo.com/prod/shipyard-dehoop/passenger-car-ferry-28621-195739.html

The Sound of Sleet Ferry also uses one VSP at each end.


And the US and British Military had mine hunter coastal ships, MHC, that used two VSP drives
at the stern and a bow thruster up front.

The old WWII war reparation crane "Herman the German" used VSP drives.

Oh, and they were invented at the University of Washington, and the rights to construction
were sold to a German company... so the WWII mine hunters M1 and M2 were VSP driven.

Hi Folks,

Thanks for all the info. Steep learning curve !

I thought all drives were approx 1/3 back from bow.

Whole new can of worms with a drive at the stern/bow thruster. I had got the impression that the hulls were double ended, I guess this is just true of tugs cruising in either direction! At the moment still thinking I'd like to go down the tug route.

Umi, picked up your build thread on LA Fire Boat,from Toesupwa links. Very nice  O0

Hi Bob,
 Yes I know other types of small vessels use this propulsion, but I was refering to the thread of tugs. Only thing I can say about voiths is that they may be simple to use, but they are bloody noisey and do they vibrate. I think though that they may be soon a thing of the past, as the 360 degree screw propulsion units steadily improve, as they are more powerful per engine Hp and easier to maintain than voiths. I could never understand why they fitted the minehunters with them though, as the noise and vibration would set of any accoustic fitted mine, but then perhaps they are supposed too!!!

Hi Longshanks, This is the Sirmar hull It's good for scale steering, and also tug towing.

Hi John,

Certainly looks the part. Must admit I had not thought about towing - you've obviously got power to spare.
Are you still using the speed 500E, what voltage?

Any idea what the weight of your model is?

How controlable is she going astern?

So many questions  :-))

Hi Longshanks, The tug is 14lb in weight I run her on 12v,  Reverse in open water OK in buoy area you have to go very slow she's very twitchy with too many revs on.
Regards

John                   
                          PS 14lb with 12.7amp battery in her.

Built the Parat but named Venture had twin VS units and loads of power to push and pull.

Hi John,

Thanks for the info, most useful.

I seem to recall reading someone saying that manoeuvring was best on 6 volts, towing on 12 volts.

Hi catengineman,

That is impressive. Bet you don't take the tow home on the back seat  ;)

The vessels at Marchwood are in the 4.5 to 5.5 tonne weight so you are right I dont take the tow's home :} :D I wish I could own them though.

Warsash training college own and run those vessels and they range from ferry to gas tankers (some have interchangeable superstructures) the last time I was there they were building a propelled jack up rig, and a tug also for training.
