Crystal next year will feature the youngest fleet in the river cruise industry. Crystal launched its river product in 2016 with the redesigned Mozart. But it will take that vessel out of service in 2020, meaning it will sail just the Crystal Bach, Crystal Debussy, Crystal Mahler and Crystal Ravel, all newbuilds that were launched in 2017. Crystal is the only river line to feature all-suite, all-balcony accommodations with butler service in every room situated above the waterline.
