Recent years have seen an increase in the number of river cruise lines positioning themselves at the top end of the market. Crystal River Cruises, launched in summer 2016, and Scenic, which started river cruises in 2008, both have well-established pedigrees in the travel industry. Crystal has sprung from the upscale ocean brand of the same name. Scenic is part of the namesake Australian-owned land vacation operator. Crystal says it brings "true luxury" to river cruising, and Scenic gives itself a self-styled six-star ranking. (Unlike hotels, there is no official rating system for riverboats.)
