HRH & I fitted the $2 shop flags to the boat and set off on a River cruised up the Tamar to Middle Island, a tiny Island in the middle of the Tamar River between Bell Bay and Beauty Point.
We stopped for a quick walk, knowing any more than a few minutes would mean staying until the tide (ebbing) ran through a cycle. I returned hastily to move to a safer anchorge after just 10 minutes (around 1PM), probably six minutes too late, the good ship "Sea Fisher" was high & dry and we were shipwrecked on a desert..ed island.
We walked some more, then ate our meagre supplies (Roast Lamb & Mint Jelly Roll, Cherries & Grapes), taking care not to quaff all our water at once. My calculations had the tide returning to set us free at 4:30Pm, in reality it was 5Pm.
We spent the last hour guesstimating the time that the water level submerged various sandbars, twigs and rocks and finally the boat.
It was a fun day, very relaxing being stranded without any hope of escape.
