It is the line's first newbuild since 2011's Riviera.
At 67,000gt and stretching 791 feet with capacity for 1,200 passengers and 800 crew, Vista is very similar in size to Riviera.
Three new culinary concepts
It offers spacious standard staterooms, three new culinary concepts and has a 2:3 crew-to-passenger ratio.
Vista's 11 culinary venues include the new Ember, a signature restaurant serving elevated American cuisine; Aquamar Kitchen, which Oceania said brings wellness offerings to a new level; and The Bakery at Baristas, an expansion of popular coffee bar Baristas.
The ship will offer an elevated mixology program with innovative specialty cocktails and new Broadway-caliber productions with contemporary dance numbers led by 'Dancing with the Stars' choreographer Britt Stewart.
'New era' for Oceania Cruises
Oceania Cruises President Frank A. Del Rio said Vista ushers in a new era for the line.
'From the smallest of design details to the largest per capita galley at sea, Vista is a marvel that will be enjoyed by guests for decades to come,' he said.
Del Rio also acknowledged the close partnership with Fincantieri and thanked everyone who had a hand in bringing Vista to life.
May 8 naming to be livestreamed
The ship is scheduled to be christened on May 8 in Valletta, Malta, with the celebrated Italian-American chef, author, restaurateur and Emmy Award-winning food personality Giada De Laurentiis serving as godmother.
The christening is due to begin at 9 p.m. CEST, and the event will be livestreamed at that time or 8 p.m. BST, 3 p.m. EDT, 12 noon PDT, 5 a.m. AEST (next day) at www.VistaCelebration.com.
