Ships

Big sisters

The world’s three largest cruise ships have sailed together for the first time off Fort Lauderdale, Florida.
Royal Caribbean International’s Oasis of the Seas, Allure of the Seas and the new Harmony of the Seas came together to celebrate the arrival of the last at her permanent base of Port Everglades.
Each vessel weighs more than 225,000 tons, has a park with nearly 12,000 plants and trees as well as an 82ft zip wire and an outdoor “aqua theatre”.

I'm not comfortable with the statement that 'each vessel weighs more than 225,000 tons'. 'Weighs'?. Do they mean 'displaces'?

I'll ask Dad a bit later. He's an old sea dog and I've been barked at once this morning already. I think I'll let sleeping sea dogs lie.
