A few days earlier, in nearby St Katherine's Dock, there was a reunion of some of the Little Ships that had been part of the heroic operation to rescue trapped troops from the beaches of Dunkirk back in 1940. Their efforts were dramatised in the recent film, Dunkirk, and one of the ships in the dock, the Elvin (above), was actually used in the film.
Also on show at St Katherine's Dock and attracting much attention was another, instantly recognisable boat - the Queen's rowbarge, Gloriana. A lasting legacy of the Queen's Diamond Jubilee in 2012, she is now managed by a charitable trust to promote better use of the Thames.
The Totally Thames Festival runs until the end of September. Details and events at:
