I did read once that the term "opening the sea cocks" to sink a ship is not correct. For the non technical minded amongst could somebody actually explain what is involved in the process please.
There are no 'sea cocks' on a ship. When you think about it any clown could sink the ship! Two possible ways I can think of (and there will be more) are to take off the sea valve intakes or if there is explosive available, blow them off,which is how I believe a VLCC was deliberately sunk in the 70s in the South Atlantic for insurance purposes.
