Well today's the day, and inspired by Adam at Messing About in Sailboats, we wandered down to the Elephant Boatyard, where Suhaili - RKJ's ketch has been lying ashore, to celebrate the day and show young Joseph a piece of yachting history.
What a surprise then to find that she was gone, launched on Monday, presumably in order to attend a 40th anniversary event elsewhere.
Oh well, it's only a short walk back up the hill, to a celebratory lunch of frankfurters, corned beef and baked beans.
Congratulations Sir Robin, you've been an inspiration to many of us for the past 40 years.
