Two hundred boats are forming a huge Olympic rings logo in Poole Harbour today, as part of a nationwide stunt.

The event's been organised by the Royal Yachting Association as a mark of support for Team GB’s sailors - who start their events in Weymouth and Portland a week tomorrow.

Boats, ranging from children’s dinghies up to 50 foot crusiers - have been decked out in the appropriate coloured bunting and flags.
