For the third year running an Armistice Day Service will be held on board the MV Havengore on the River Thames in Central London.
Havengore, accompanied by other vessels, will cover much the same route as she did during Sir Winston Churchill's State Funeral.
Departing from St Katharine's Pier at about 10.10am she will pass many of London's major landmarks on her journey up river to the waters between St Thomas' Hospital and the Palace of Westminster.
A solemn remembrance service, led by Revd Roger Hall, will start at 10.50am.
As Big Ben chimes 11am the two minute silence will be observed and then the service will culminate in the casting of a wreath onto the waters of the Thames.
