The cars on board of the yachts.

Maybe its a strange question,and no it had nothing to do with my user name.
Does anybody know something about the cars onboard of the yachts.
Do they have any?
I know that a favorite of mine (cedar sea) in the time of delivery had one,it was a special made range rover in the same color of the yacht.
Can somebody help me with that.
thanks a lot.
