Oh! I saw Octopus somewhere in the last few years! I'm not a boat person but I do enjoy wandering round some of the more poncy marinas and muttering how disgustingly wealthy some people must be, especially when you consider the number of decent sized boats just bobbing about on their anchor.
Couple of years back we were in Ibiza and I was chatting to a bloke at the end of the gangway of a posh yacht. Ronaldo had rented it, and Messi's was parked up next to it. I can't remember the exact costs but Messi's was much smaller!
I can honestly say that however wealthy I was the last thing I would buy is a yacht. Being extremely susceptible to sea sickness it would just be a very expensive way of making me ill.
I must admit that I did not know who Paul Allen was either.
As far as private helicoptr operations are concerned my old company serviced one VVIP who ran two private Sikorski S92 helicopters which cost around 32 million USD each. One in the Middle East and one in the UK.
They were kept on three hour standby for him at a cost of around 500,000 USD per annum each.
