Running Costs

Can anyone tell me how much some of these yachts cost to run per annum? I don't mean crew or staff salaries but rather the cost of the yacht itself such as fuel, moorings, insurance and any other accuring costs. I really need this information for a presentation and any help would be apprieciated. I need some sort of guidline and if even an estimate to maintain the accuracy of my presentation because quite frankly i have not a clue. If this thread has already been created then im sorry for creating a new one but i'm new to the site and a bit lazy to do a search. For those of you who reply to this id like to say thanks beforehand as i may not be able to reply to some if any. To the staff, keep up the good work.
