The collections onboard Oceania’s newest ship are truly impressive: more than 2,000 pieces by both famous and emerging artists detailed in a catalog and audio tour — among them a signed Picasso lithograph on Deck 5, and more than a half dozen Picasso etchings in the Grand Bar.

Like its younger sister Riviera, Marina is home to etchings by Picasso, as well as lithographs by Joan Miró in the Grand Bar and Damien Hirst’s “Spin” in the Canyon Ranch SpaClub. Both ships also have a handcrafted Lalique Grand Staircase that's a chef d'oeuvre in and of itself.

Celebrity’s fleet features about $60 million in contemporary art — much of it on its five Solstice-class ships — with iPads that offer digital tours. Notably, Reflection has works by American icons Jeff Koons and Robert Rauschenberg, as well as a giant living tree installation by Miami-based Bert Rodriguez suspended in the Grand Foyer. Silhouette has the mesmerizing Mirror by British-Indian sculptor Anish Kapoor.

Royal Caribbean has amassed a fleet-wide collection worth $120 million, and Quantum of the Seas debuted in 2014 with $5 million in contemporary art onboard — including a self-portrait by Andy Warhol, an atrium wall installation by New York-based Paul Villinski depicting 210 butterflies, and an eight-ton magenta bear ("from afar") by Lawrence Argent, known for public art, that looms over the SeaPlex.

Equally art-filled as her sister Quantum, Anthem of the Seas arrived in 2015 with 3,000 works onboard — including colorful, interactive commissions and a whimsical SeaPlex sculpture of a giant giraffe by Morocco-based Jean-Francois Fourtou.

Allure’s notable works include Korean artist Keysook Geum’s aft elevator lobby installation of 34 floating dresses, and the multicolored creations of Neo-pop artist Romero Britto in Central Park. Oasis’s cache includes Puerto Rico-born Carlos Betancourt’s 100-foot-high “A Flock of Seagulls” aluminum sculpture.

Nieuw Amsterdam has $3 million in artwork onboard — including pieces in the style of the Dutch Masters, works by Andy Warhol, Roy Lichtenstein, and photorealist Richard Estes. A translucent sculpture of the New York City skyline — by Italian husband and wife duo Gilbert Lebigre and Corinne Roger — hangs upside down in the Atrium.

An audio tour details the $2 million collection onboard Cunard’s Queen Victoria, which comprises more than 500 works by British painters, sculptors, and glass artists, as well as treasured circa-1840 etchings by Queen Victoria and Prince Albert of their three dogs.

This luxurious ship from German line Hapag-Lloyd is home to a deep collection of around 890 works of contemporary art by David Hockney, Damien Hirst, Gerhard Richter, Ólafur Elíasson, and Hans Hartung, among other bold-faced names.

While Costa ships are known for their over-the-top décor, Luminosa offers a modicum of sophistication with its collection of figurative art, including Fernando Botero’s “Reclining Woman 2004” in the Supernova Atrium.
