After a succession of delays, the first ship in the Ritz-Carlton Yacht Collection is scheduled to launch in May. The company originally ordered three identical vessels, the first of which was due to begin operations in 2020. Reservations are now being accepted for cruises this August. Evrima — the name means “Discovery” in Greek — will be 620 feet long, so it is fairly sizable, even as superyachts go. (The world’s largest private superyacht, Azzam, owned by Sheikh Khalifa bin Zayed Al Nahyan, the emir of Abu Dhabi, is 592 feet in length.) The 298 passengers will be accommodated in 149 suites in six categories, ranging from Terrace Suites (300 square feet) to the two Owner’s Suites (1,091 square feet).
