Oceania Cruises is about to transform one of its most celebrated ships from the ground up — and the details are extraordinary.

A former fighter pilot, a man who rowed across the North Atlantic, the son of Everest's conqueror, and a ballet star who defected from Cold War China — meet the extraordinary minds joining Seabourn's 145-day world cruise, and prepare to rethink what a sea voyage can actually be.

Forget the megaship Mediterranean. Aurora Expeditions is reimagining European cruising with 19 intimate voyages, a purpose-built ship and onboard historians who transform coastlines, ancient ruins and folklore-soaked islands into something you'll never find in a port crowd.

SeaDream Yacht Club is adding more than 80 new ports across three seasons, taking its intimate mega-yachts to harbors that larger ships will never reach – from remote Scottish isles to Caribbean hideaways.
