What is it with millionaires and yachts?
I hate boats, even on a calm day in a lake which is only about 2 m deep I'm constantly convinced the damn thing is going to sink.
Do people actually like being on boats, it's basically like being in a cramped apartment that is really inconvenient to get to and from, that constantly experiences a never-ending earthquake, why is that anyone's idea of a good time?
Also I really hope somebody has tested that submarine extensively.
