Magowan was appointed in September 2017 and held responsibility for the commercial strategy and the development of the Cyprus-based line’s presence and sales distribution, with a specific focus on the UK market.
In February he said Celestyal was “well on course” to carry 5,000 British guests this year – about five times more than in 2018.
Leslie Peden, chief commercial officer, said: "We would like to thank Andrew for the contribution he made during his tenure and we wish him well in his future endeavours."
Celestyal Cruises said it was taking the opportunity to evaluate the future European location and scope of the replacement role, which will be announced in due course.
