My issue is that the Kusari Luxury Transport and the Yacht seem to be essentially the same thing, at least they sound like they're supposed to be. They're luxury transport-class ships for people with lots of money. But the Kusari version is far superior, even if it lacks the armor of the Yacht, and is FAR less expensive even though each one is supposedly custom-made for the owner.
Though it turns out they have the same speed, 100 impulse/160 thrust.
