The Thames Diamond Jubilee Pageant was a parade on 3 June 2012 of more than 1,000 ships and boats along the River Thames in London, as part of the celebrations of the Diamond Jubilee of Elizabeth II. The Queen, Prince Philip and other members of the Royal Family were aboard vessels that took part in the parade, which was watched by more than 1.2 million spectators from the Embankments. The vessels that took part included military, commercial and pleasure craft. According to Guinness World Records, this was the largest ever parade of boats, surpassing the previous record of 327 vessels set in Bremerhaven, Germany, in 2011.[1] Sailing vessels and others too tall to pass under the bridges were moored as an "Avenue of Sail" downstream of Tower Bridge.
