The six-part documentary was filmed aboard Princess Cruises’ Majestic Princess last year during sailings to Asia, Australia and New Zealand.
Episodes will air weekly on ITV1 at 8.30pm, starting January 3.
Series six will introduce a number of new faces including Captain Dino Sagani, who has worked for Princess for 25 years and has served on several of the line’s ships.
Among those taking centre stage will be hotel services engineer Scott Grayson, who is balancing his role maintaining the 143,000-tonne ship with fathering his new born baby daughter.
Actor Anthony Head will provide the voiceover for the series.
