Silversea vs. Seabourn Cruise Line Silversea or Seabourn? That's a tough question for cruisers waffling between the two lines for their next luxury voyage. Both offer fairly intimate ships that sail the globe, and both have new vessels -- Silver Muse and Seabourn Ovation -- with more new-builds in the works. Both lines offer sophisticated and personalized service, as well as all-inclusive cruise fares that cover all beverages and gratuities. Silversea cruises -- with a butler catering to every cabin -- tend to be a bit more formal, while Seabourn ships offer a true sense of community via amenities such as Seabourn Square (a living-room style concierge area), a well-designed coffeehouse and an aft water sports platform. So, in what ways do these lines actually differ? Let's compare Silversea vs. Seabourn.
