Hello,
I know that a charge can build up in a car because tires insulate it from the ground. Does this effect translate to transporting cars on boats and trains? I mean: are cars grounded to the boat/train frame while in transport to reduce the possibility of a large static charge on the car?
Thanks for reading.

I am not sure what the problem might be with a charge on the car, any more than just sliding out of it in a gas station on a winter day. It is really moot on a transporter since they are chained down.
Modern motor tyres have a measurable resistance and so a car or trailer is effectively connected to the ground all the time.
The charge when you slide out of a car is between you and the car(& ground).
I am in a dispute with Mazda over some gouges that I contend took place during shipping before I got the car. They're rusting. If it's as you say, and there is no 25 gauge grounding cable... I'm out of luck. Thanks for replying.

Most modern tires have enough conductance that this isn't really much of a problem.
The few cars I've seen loaded on to ferry or train are *chained* down, so any static charge would be grounded through the chains. Not that it's much of a hazard anyway. (a car not chained down on a rolling deck is more of a hazard than any static shock).
