River Cruise Tauck's Jewel-class river ships getting larger cabins By Michelle Baran / January 21, 2016 Share 1 -- Tauck plans to increase the size of some cabins on its five Jewel-class river ships. The second passenger deck on each ship (called the Ruby Deck), where there are currently 30 cabins at 150 square feet, will be replaced with 20 cabins measuring 225 square feet.After the work, there will be 49 cabins on each vessel, down from 59. The Swiss Emerald and Swiss Sapphire, two ships that sail in France, will be reconfigured next winter, before the 2017 season. The Swiss Jewel, Treasures and Esprit will be refurbished the following winter.Also, the Bistro restaurant will be renamed Arthur's, named for company founder Arthur Tauck Sr. The company's Inspiration-class ships already have Arthur's restaurants, which are a casual alternative to the fine dining in the main restaurant.With the new reconfiguration, Tauck will eliminate distinctions between its Jewel and Inspiration classes of ships. Tauck will instead refer to its ships collectively as the Tauck Destination Fleet.Tauck's Inspiration-class ships, the Inspire and Savor, launched in 2014. The Grace and Joy will launch later this year.
