Gallery: Jubilant’s 21st birthday

The Jubilant Trust celebrated its 21st birthday on Saturday with Royal Shallop Jubilant leading a 15-strong flotilla down the River Thames from Isleworth to Greenwich’s Royal Observatory carrying an “atomic” clock, which ticks more than 400 million million times a second.

Here’s a selection of photos from the event:

*The Strontium ion clock is loaded aboard* Jubilant at Isleworth.

*The flotilla had assembled by the London Apprentice Pub which provided bacon sandwiches and coffee to fortify the rowers. The money collected was given to Macmillan Nurses by the landlady Magda.*

*Rowing past Chiswick Pier, without the full strength of the ebb she was about 15 minutes behind the clock at this stage.*

*MVS* Blue Light intercepts the clock by the OXO Tower. Jubilant continues on to the National Maritime Museum. We had made up time and arrived at the rendez vous point on time. A Port of London Authority (PLA) Harbour Master Launch now took over the lead from London Port Health Authority (LPHA) cutter Londinium III.

*The flotilla approaches Tower Bridge passing the Shard and the London City Hall.*
