One of the world's biggest cruise ships is heading to New Orleans.

Norwegian Cruise Line's 4,000-passenger Norwegian Breakaway will begin sailing from the city in November 2018, the line has announced.

At 145,655 tons, Breakaway is the 16th largest cruise ship in the world, and it will be the largest cruise vessel ever to sail from New Orleans.

Breakaway will reposition to New Orleans from the Baltic, where it will spend the summer of 2018. It will remain in the city through April 2019, operating a series of seven-, 10- and 11-day cruises to the Western Caribbean.

Ports of call for the vessel will include Cozumel and Costa Maya, Mexico; Ocho Rios, Jamaica; George Town, Grand Cayman; Roatán, Honduras; and Harvest Caye, Belize.

Norwegian's announcement comes just five months after Royal Caribbean revealed it would resume cruises from New Orleans in late 2018 after a three-year absence from the city. Royal Caribbean is sending its 2,050-passenger Vision of the Seas to New Orleans.

Also sailing out of New Orleans are two Carnival ships, the 3,652-passenger Carnival Dream and 3,143-passenger Carnival Triumph.

New Orleans also is a hub for riverboats that cruise the Mississippi River.
