This is what happens when you leave a boat unattended on a rising tide with the wind offshore.
Embarrassing. Everyone walking their dogs along the foreshore stopped to watch. Luckily the breeze blew her into the shadow of the pub and the tide brought her back in before anyone had to get wet waist deep to stop her floating off to France.

As I hung over the stern up to my elbows in cold water disconnecting us, a voice rang out from the pub: "Should've gone to Specsavers!"
