Sea Cadets from across the UK are in pole position as they will be leading their Patron HM The Queen's Jubilee barge, The Spirit of Chartwell, down the Thames on June 3 in celebration of her Diamond Jubilee.

Cadets are training hard in preparation as they will be the focal point in a huge procession of over 1,000 vessels as they crowd the Thames to honour the Queen’s jubilee as part of a huge Thames pageant, the likes of which hasn’t been seen since 1717.

The boats, Trinity 500's, were specially designed for Sea Cadets by Olympic dinghy medallist Jo Richards and will be fitted with an outboard motor supplied by Suzuki GB.

Also taking part is the flagship, TS Royalist which will be moored in the river as part of the Avenue of Sail.

We will be centre stage again on Tuesday 5th when Leading Cadet Hannah from Beckenham & Dulwich unit will be leading the Diamond Jubilee National Service of Thanksgiving at St Pauls which will be attended by HM The Queen and the Royal Family. Hannah is 16 and was recently promoted to Leading Cadet, she is also the first London cadet to be awarded the Aviation Bronze Wings, the proficiency for flying.
