Crowds lined bridges over the Thames on Wednesday lunchtime to see a flotilla of historic vessels to mark the Queen becoming Britain's longest-reigning monarch.
The boats assembled downriver of Tower Bridge and made their way to the Houses of Parliament.
Tower Bridge was raised in salute as the boats passed by.
Vessels taking part included the royal row-barge Gloriana as well as Havengore (best known for its role in Churchill's funeral) and the newly restored fire boat Massey Shaw.
