The Isle of Man's new Lieutenant Governor, Vice Admiral Sir Paul Haddacks, is due to arrive next Friday on a Royal Navy vessel.
Air Marshal Ian Macfadyen was the previous Lieutenant Governor
Sir Paul, 58, who will be the Queen's representative on the island, sails from the Pier Head in Liverpool on HMS Severn, a new offshore patrol vessel.
The swearing in will take place in Castle Rushen on Monday 17 October.
Air Marshal Ian Macfadyen OBE, the previous Lieutenant Governor, relinquished his post last month.
After arriving at the Victoria Pier in Douglas next Friday, Sir Paul, who will be accompanied by Lady Penny Haddacks, will be welcomed at an official reception at the Sea Terminal.
He has had a distinguished career in the Royal Navy, which has seen him serve as Commander of the UK task force in the Gulf in 1990 and as UK military representative at NATO headquarters and EU headquarters.
He was made the director and chief executive of International Military Staff at NATO headquarters in Brussels in 2001, being responsible for personnel from 30 nations.
He left the Royal Navy in November 2004.
It is thought to be the first time a Royal Navy vessel will have sailed from the Pier Head in Liverpool for many years.
