Hi Salty,
If you are using a re-skinned tug then you will see her as you have made her but other players will see the original version. However if you are using one of the "Types of tug", she will behave as you drive her and will also show the same performance to other players. If you think about it, other players do not see your controls, only the way your ship moves about. I hope I make sense for you!
Regards,
Angus.
