Ellen Bettridge, chief executive and president of Uniworld River Cruises, said the line is "overjoyed" to sail along the Nile river and provide "an unmatched look at the destination".
"We’re excited for our guests to experience the ship as it fully embodies what they love most when sailing with us, exquisite design and experiences they won’t find anywhere else," Bettridge added.
"Everything from the artwork to the ceilings to the ship’s bow was thought out and sourced by the local community."
