A yacht in the Bristol Channel

I went down to the beach again this morning and through my binoculars, I could see a little white object some way off the coast of Lynton on the Devon Coast. The sea was quite choppy, so it was difficult to see how far away this object actually was, but after a couple of hours and coffees later, this tiny little yacht came into view.  At a rough guess, it had travelled between 8 and 10 miles whilst I had been watching it. As it passed me, it seemed to be heading in the direction of Barry and The Cardiff Barrage!
