Small ship line Seabourn have announced the names of its two newest ships. The vessels were ordered last year. Seabourn Encore will be launched in late 2016 and Seabourn Ovation will go after in spring 2018.

Both 40,350-ton ships will maintain Seabourn’s high space per guest ratio and will offer a highly personalised service. Encore and Ovation will be larger than their Odyssey-class sister ships Seabourn Quest, Seabourn Sojourn and Seabourn Odyssey. They will feature an additional 12th deck, modern design elements, newly expanded public areas and innovations.

Adam D. Tihany, hospitality design icon, will design all guest areas and dining venues on board the vessels, which are expected to carry 604 passengers each, based on double occupancy. More than 150 extra guests (compared to 450 on the other Seabourn ships) will be accommodated in Encore and Ovation all-balcony suites.

According to Seabourn President Richard Meadows, the words “Ovation” and “Encore” paid tribute to the “tremendous success and outstanding accomplishments” their current ships had achieved, and were the perfect names to celebrate the expanding fleet of Seabourn. The addition of the new ships means that the luxury line will have the youngest ultra-deluxe fleet in cruise industry.

Seabourn said further details about the new ships will be revealed over the coming months. The line offers wide-ranging itineraries, sailing to every continent of the world, apart from Antarctica. The port calls are in both marquee cities and “off the beaten path” destinations.

Seabourn Encore is said to embark on voyages spanning Australia and New Zealand, Arabia, India and South-east Asia during her maiden season.
