(2:30 p.m. EDT) -- Carnival Cruise Line's next new ship, Carnival Horizon, will spend its first year in 2018 sailing from a variety of homeports, including Barcelona, New York and Miami.

The 3,936-passenger ship, a sister to Carnival Vista, will debut April 2018 with a series of Mediterranean sailings departing from Barcelona, Spain. Its maiden voyage will kick off April 2 and span 13 nights, calling at Rome, Naples, Dubrovnik, Greece, Sicily, Malta and Sardinia. Two seven-night cruises and a 10-night cruise, all in the Mediterranean, will follow.

On May 9, Carnival Horizon will reposition to New York with a 14-night transatlantic trip before beginning a series of eight-night sailings to the Caribbean throughout the summer. Stops on the Caribbean cruises include Grand Turk, San Juan and Amber Cove.

Starting September 22, Carnival Horizon will continue to its next homeport, Miami, for a regular year-round schedule of six- and eight-night Caribbean cruises. Following a special two-night cruise to Nassau September 20, the ship will depart from Miami on Saturdays and Sundays. The Saturday cruises will be eight nights and have two itineraries: Grand Turk, La Romana, Curacao and Aruba for one and Grand Turk, San Juan, St. Kitts and St. Maarten for the other. The Sunday cruises will be six nights and call at Ochos Rios, Grand Cayman and Cozumel.

Carnival Horizon is under construction at Fincantieri shipyard in Italy. The ship will have many of the same features that debuted on Carnival Vista, such as the SkyRide, the IMAX Theatre, the WaterWorks aqua park with Kaleid-o-slide, and new stateroom categories, including the Family Harbor cabins and tropical Havana Cabana cabins and suites; suites include exclusive daytime access to the Havana Bar and pool.

More features exclusive to Carnival Horizon, including restaurants, bars and outdoor spaces, will be announced later.
