When I captured this image of a Rescue Rigid Inflatable Boat (RIB) in August 2009 motoring in Southampton Water, I assumed (perhaps wrongly) that it was affiliated to the Royal National Lifeboat Institution (RNLI). I was unaware at that time that there were independent lifeboats operating in Southampton Water and the Solent. As I captured the image from the Moat Wall of Calshot Castle, I am now, (in 2023), more inclined to believe that she is an independently operated rescue vessel most probably from the area of the River Hamble.
