Norwegian Cruise Line is to base its newest ship Norwegian Escape in Miami year-round.

The ship, set to launch in October, will sail on eastern Caribbean itineraries to Tortola, British Virgin Islands; St Thomas, US Virgin Islands; and Nassau, Bahamas.

The line is also offering a 10-night transatlantic cruise from Southampton to Miami on October 29, 2015 as the ship is repositioned.

Kevin Sheehan, Norwegian’s chief executive, said: “Norwegian Escape’s arrival to Miami coincides with Norwegian Epic’s year-round Europe deployment, demonstrating the balanced approach we used to develop our winter 2015/16 deployment and ensuring that we had a varied offering of premium destinations that would be exciting to our guests.

“Much of this deployment was designed based on feedback from our guests and travel partners, and we know they will be happy with the changes and enhancements we have made.”

The ship will be the line’s largest when it launches, with 4,200 berths.

Norwegian Getaway will continue to sail year round from Miami on seven-night Western Caribbean cruises to Norwegian’s private island, Great Stirrup Cay, Bahamas; Ocho Rios, Jamaica; George Town, Grand Cayman; and Cozumel, Mexico.
