The Silversea Group announced that it has purchased Canodros SA, the premier Ecuadorian tourism company that operates in the Galapagos Islands, and their upmarket expedition ship, Galapagos Explorer II.   Silversea plans to add Galapagos Explorer II to its ultra-luxury fleet of six ships after the all-suite, 100-guest vessel undergoes a major refurbishment in September 2013 and is given a new name, the Silver Galapagos.  The 4077-ton ship offers the stylish elegance of a mega-yacht, attentive onboard service and an enriching naturalist education program. All of its 50 spacious suites feature ocean views and 24 include private balconies.  It also offers connecting cabins.  A rare find in Galapagos.  Public spaces include a restaurant, piano bar, library and Internet station, main lounge, outdoor bar, two outdoor whirlpools, and a marine observation deck.
