How long does a ship take from New York to London England?

You can fly across the Atlantic in six hours but crossing it by sea takes six days. This is a chance to contemplate the vastness of the ocean as Queen Mary 2 steams along what's called a Great Circle track, sailing east-northeast from south of Cape Race, Newfoundland to the Bishop Rock lighthouse at Land's End, the entrance to the English Channel.
