Set to debut in 2028, ms Harmonie has been custom-built for the Rhône and will accommodate up to 130 guests.
It will serve as the sister ship to ms Lumière, which made its maiden voyage in March 2026 and has also been purposefully designed to sail the iconic European river.
“River cruising continues to be one of the most popular ways guests first experience Tauck, and the feedback our river guests have shared over the years shapes every ship we build,” said Jennifer Tombaugh, Chief Executive Officer at Tauck.
