Are cruise ships built for the transatlantic run?

The Queen Mary 2 was built for transatlantic crossings, but much smaller ships can make the crossing easily. In 1995, I crossed the Atlantic from New York to the Azores on the Royal Princess (which was not the same ship as the current Royal Princess), which was about one-fourth the size of the QM2. Just about any seaworthy Passenger ship can navigate the Atlantic safely, if not comfortably.
