A few weeks ago we went to Rhodes for a couple of weeks holiday. I always feel a bit guilty "polluting" the earth by taking a plane, along with a couple of hundred other people, just to get some time away from it all.
We were sat on the balcony, sipping a drink, when a huge military looking boat (ship?) entered the bay and moored up. I had a look, through the binoculars and read the name "Sputnik"! It's not military but it is a supply vessel to a superyacht "Queen K"! They are owned by a russian billionaire. So, you don't just buy a superyacht, you also buy a supply ship, complete with luxury launches ( one for each boat/ship) and a helicopter. (Google them for full details).

I don't feel as guilty about my package holiday now!
