I have a story that goes with this thread,
I had arrived two days early at the lake venue of an away regatta. The idea was to familiarise myself with the venue and set up the boat. It was mid week and I was out sailing in light winds, with no another boats on the lake.
Its a huge piece of water and I'm roughly mid lake when I spot something strange some few hundred meters away so I sail over to investigate. It turns out to be a guy swimming in his life jacket.
I pull him on board and he tells me he has a small 'trailer sailor' [mono] and while returning to the **** from the bow he slipped and fell overboard. He's on his own and so the boat slowly sails away leaving him stranded.

We sail off in the direction of the wind and find his little boat wedged in the shoreline weed some odd k's away.

He's a very happy and grateful chap when I leave him back with his boat.
