Silver Nova
Silversea Cruises
The 728-passenger Silver Nova marks a big change for Silversea because its suites run from front to back across four decks (instead of the front half of the ship, as is the case on the line’s other vessels) and a revolutionary system of fuel cells and batteries allows the vessel to be 100% emission-free in port. Eight dining venues include the Salt Kitchen for regional dishes, and new Marquee, where you grill steaks on hot rocks under the stars. For the ultimate indulgence, try the Roman-inspired Otium spa.
Silver Nova launches in August and is spending its maiden season in the Mediterranean; prices from £4,600 with door-to-door chauffeur service. silversea.com
