Yachts line the Harbour in Monaco - Monte Carlo
To own a superyacht, you can't just be rich - you have to rolling-in-the-billions rich.
And one of the best in the world is built by Sunseeker, a British company that customises each yacht to the very demanding specs of their elite clientele.
These boats go for millions of pounds, depending on whether you want four en-suite bathrooms or a giant jacuzzi or whatever luxury you can think of.
If you want to spot one of these, your best bet is a trip down to Cape Town's V&A Waterfront, where all kinds of yacht dock with their luxury travellers.
