I captured this image of the Rigid Inflatable Boat (RIB) Atomic in May 2011 from the deck of the Red Funnel car and passenger ferry Red Falcon. What I did not notice at that time was that the yacht registration GBR54R was painted on the side of the RIB's cockpit. A limited search of the Internet (April 2022) revealed that there was a racing yacht also named Atomic that carried the same GBR54R number at the same time and was a participant in the 2011 Isle of Wight Round the Island Race. This took place in June 2011. My guess (which might be incorrect) is that the RIB and racing yacht were linked and that when I saw the RIB she was putting out temporary marker buoys to allow the yacht to complete pre-race exercises.
