I have been white-water rafting, white-water kayaking and white-water canoeing. Now I can say I have been white-water sailing. Today we went through the Menai Strait, between Wales mainland and the island of Anglesey. The tide floods in from both ends and ebbs out both ends. In the middle of this confusion is a stretch of about one mile, called the Swellies, that is between two bridges and their structures in the water. The bridges are located here because it is the narrowest spot, of course. Plus, there are several rock obstructions: Platters, North Platters, Swelly Rock, Gored Gock, Cribbia Rock and Brittania Rock. And just in case you missed all these rocks there is Cheese Rock right in the middle of the channel. It was utter chaos in the water and you have to try to time it for slack high water. We timed it, but I am not sure about the slack business, we never had less than a four knot boost from the current. It was definitely white-water sailing. The picture gives just a hint of the power of the water. Whirlpools forming all over the place that would turn the boat this way and that.
