    de Mist Naval Tug
    Hi Glynn Thanks for your response. I was hoping that the dreaded words "Voith Schneider" would not come up as I have no way to engineer or buy a VSP (even looked in "Graupner" site but no info on buying units and I think it will break the pensioners bank anyway! This is my first contemplated tug build so would be interested if the model tug Guys would perhaps advise what they do when the dreaded 2 words come up...do they cheat a little below the surface and substitute other propulsion sources when a VSP would be "true scale"? Glynn, what Dorbyl built SA tugs do you have knowledge off that are not VSP equipped? I think the other older Simonstown Naval tug is the "de Nuys" but I presume she will also be Voith Schneider Propeller driven. Regards and Happy New Year to you and all on MB's.

    Hi Gerd, it's not my plan! The plan is from 'green72west' who started this thread and seems to be confusing Schottel and Voith-Schneider. Either that or he wants to use two Z-Drives instead of the Voith drives. His intention is not clear. Either way he doesn't need to cut chunks out of the keel, that's nuts😲 Cheers, Doug 😎

    Hi Haig, seems to be a common mistake to get Schottel Drives (Z-Drives) and Voith - Schneider confused with one another! First two pics show a twin Voith propeller on a tug hull (as on the plan above) and the operating principle. 3rd pic is cross section of the Z-Drive as produced by the Schottel company. it is a 360° rotating 'pod'. Newer versions have electric motors built into the pod and don't need the mechanical Z transmission from inside the hull. With such pods under bow and stern even bow and stern side thrusters are redundant 😊 4th pic is the Graupner version, Mk II. https://www.graupner.com/Schottel-Drive-II-new-version-/2335/ Cheers, Doug 😎
