Rendering of Amadeus Star

(9:13 a.m. EST) -- Amadeus by Lueftner has confirmed it will be build a new ship for launch next year, Amadeus Star.

The 164-passenger ship will be a sister to Amadeus Queen, which launches next month.

It will have 82 cabins, a recessed aft outdoor deck and a new concept for Amadeus -- a "wine cellar bar" at the back of the ship.

The line has confirmed that both ships will be marketed towards a millennial audience, as reported in January.

Owner Wolfgang Luftner said: "Attracting millennials is not about changing the color of your ship.

"It's about flexibility -- flexibility in terms of dining times, what food you serve onboard and what type of excursions you offer."

His daughter, Corina, also part of the business and a millennial herself, added: "I don't want a silent disco, I want to see the destination."

The line will have open dining from 6 p.m. to 9 p.m., a variety of healthy food options and pre-load apps for passengers to do their own shore excursions. The line will also have a yoga instructor onboard who will offer more than just lessons on the sundeck, but act more as a guide to yoga concepts and lifestyle.

He ruled out offering any onboard activities such as silent discos and pajama parties, referring to the offerings by U by Uniworld, which is aimed at millennials. This week Uniworld revealed it would be scrapping the upper age restriction on its two millennial ships.

Dr Wolfgang said their core age groups of 50s to 80s had not spiked down as a result of the millennial focus, but added that it was "still early days" to see those changes.
