On Saturday the 11th of June 2016, members of City of London and Lower Thames MVS units took part in the Queen’s Royal flotilla to celebrate Her Majesty’s 90th birthday. The MVS was specifically asked by the organisers of the Queen's Royal Barge (Gloriana) to provide marshalling services on the day. Rigid Inflatable Boats (RIBs) Seax from City of London MVS and Annie from Lower Thames MVS ensured that man-powered vessels in the Flotilla remained in formation and were protected from faster-moving, motorised river traffic. Members of the City of London and Lower Thames MVS units met up at 0900 at HMS President, near St Katherine Docks prior to the event - which was due to start at 1100. The two main vessels in the flotilla – Gloriana and Havengore – moored up at HMS President before heading towards Lambeth Palace with all the other vessels in the flotilla. It was a pleasant journey up to Lambeth Bridge. Annie travelled behind Gloriana on the southern side of the Thames, and Seax travelled along the northern bank of the Thames. At 1205 Seax and Annie assisted with marshalling vessels when the flotilla turned around to head back to St Katherine Docks. The journey back was definitely more eventful for the MVS! The MVS stopped motorised tourist RIBs splitting the flotilla on many occasions; and Annie even prevented Gloriana from running aground near HMS Belfast when she was trying to complete a manoeuvre! The MVS also had to order two tourist vessels away as they were blocking Gloriana mooring at HMS President. Overall the flotilla made it back to HMS President earlier than expected, and it was clear the MVS contributed to the success of the day - by ensuring that all vessels made it back safely. Thanks goes to members from City of London (Zadie Vaca, Dávid Vajnai, Martin Molloy, Francois Miguelez and Eamon Hynes) and Lower Thames MVS (Michael Hegarty, Kevin Marshall, Alan Metcalf) who contributed their time and maritime skills during the flotilla. Thanks also goes to members who came along to cheer the MVS on at the sidelines and join us for a celebratory drink afterwards!
