The Brits are selling one of their aircraft carriers, this one a small one set up to launch STOL fighters like the Tornado. The ad describes it as complete except for engines and generators. Here you are, 17.000 tons of pure class.
Be the envy of your yacht club or other social group.
Maybe the Argentinians could buy it.
A quick check values the boat at $336/ton or $5,712,000.
