This is most a challenge.
Is it possible to make a exact model that reflects in scale the velocity and rate of turn of the real ship?
At least as a test of the modelists capacity challenge.
Markus is the Rittmaster here, what you say about that? Is it possible?

the original ship had a topspeed of 30kts (56 kilometers per hour) and a minimum turning diameter (at 20kts) of approx.900 meters
this would be at 1:200:
speed 0.28 kilometers an hour ;D ;D
turning diameter 4,5 meters
so the scale speed is already reached at 5-10% trottle, a turning diameter of 4,5 meters is no problem at all using a v-mixer

found some additional data:
speed rudder turning_time diameter speed_loss
9,5 kn 15° 0,46 min 1188 m 3,5 kn
10 kn full. 1,03 min 785 m 5,1 kn
20,4 kn 25° 0,30 min 897 m 6,4 kn

Most (dare I say all) scale model boats are vastly overpowered compared to their real life counterparts. As Markus says, the models all outperform the original both in speed and turing radius. If you downrated the power to match the true scale performance, the model would be frustrating to sail. Probably very difficult as well...... With modern supertankers, you need anything between 30 mins and an hour to get to full speed. How boring would that be ?

I don't think i would ever have the patience let alone the skill to do what you lot have done, customise it beyond belief lol, I've been trying to get my head around some of the diagrams uploaded about the motors for the gun turrets etc.....i still cant understand it haha

yes, some of the electric circuits are a bit tricky, but mostly the complicated ones show special solutions for people who want more functions than their radio control allows..
on the other hand i don't think i had the patience or skills to customize the decking like some of us did...hats off to those who made it !

I agree that to make the model sailing accurate would be not very desirable. Amongst other things of course is that the "sea" would also not be to scale. A 6 ft swell would be only 1 cm on a pond, and a 12 ft one which would tend to have breaking tops only 2 cm which would not break on a pond!!!
Even the bow waves never look quite right on a model versus the real thing.
Static models do not have this problem, as making a sea from (say) plaster of paris can easily be moulded to look good. I remember one of the Victory builders made a "sea" for his model to drop into (the hull was complete, and could be lifted out if needed). The base was made of perspex with a cutout for the hull, the vessel was in full sail towing one of its boats, fantastic job!
