Silversea Cruises has unveiled an extensive line-up of worldwide voyages for 2013 -- all on sale now. And complementing what is arguably the most expansive schedule of any cruise line, are attractive savings incentives in 2013 that include almost double the number of Free Air gateways available (on select sailings) to travelers departing from the U.S and Canada, and Onboard Spending Credits of up to $1,500 per suite on all voyages (with the exception of Silversea Expeditions).

In 2013, the company's six elite ships will offer over 200 voyages, visiting more than 450 destinations on seven continents. Highlighting the program is Silver Whisper's 115-day World Cruise, Silver Spirit's inaugural calls in Hawaii (last visited by Silversea in 2010), and Silver Explorer's new expedition cruises to Canada's beautiful Hudson Bay.

Also noteworthy are Silversea's 32 new ports of call, which include 21 just for Silver Explorer alone. Collectively, the line's other ships will offer 11 new destinations: Soller de Majorca, Spain; Sabang (Pulau Weh), Indonesia; Port Arthur, Australia; Liverpool, U.K.; Klaipeda, Lithuania; Saaremaa, Estonia; Baie-Comeau (Quebec), Canada; Chios, Greece; Portsmouth, Dominica; Fanning Island, Kiribati; and Fukuoka, Japan.

"For the discerning luxury traveler, our 2013 schedule, with over 30 new ports of call, offers unparalleled opportunities for unique and life-enriching journeys to all corners of the globe," said Steve Tucker, Silversea's vice president of field sales for North America. "With almost double the number of Free Air gateways and generous Onboard Spending Credits now available, this is the perfect time to finalize your travel plans for next year -- and enjoy an affordable luxury vacation exploring the world with Silversea."
