Low Y was expected to head straight for France, away from the Fastnet, but at the last minute it turned and headed north towards the rock. On the evening of August th, the storm slammed into the race. What happened then, as things developed, was that it did get very uncomfortable. The chaotic fury of the storm caused rapid changes in wind direction, which created towering waves that battered the boats from all sides, making them almost uncontrollable. Matt and the other experienced sailors were shocked and confused. The crests of waves would break way above you and you could just hear this rumbling and you'd look around thinking, "Where on earth is this coming from?" To your horror, you'd see it coming down towards the boat. That was certainly one of the most frightening things about the ordeal not knowing where these breaking waves were coming from. That's because at the heart of the storm a highly unusual event was taking place. When all the weather records were analysed, they revealed the presence of a unique phenomenon a freak event where a tongue of cold dry air from high in the stratosphere, a "surface jet", forced itself down into the heart of the storm. The effect was like turbo charging. It split a normal storm into several systems, each with the strength of a hurricane. Early next morning, Mayday calls were jamming the emergency radio frequency. Reports were coming in thick and fast of foot waves like blocks of flats and mileanhour winds. The one that caused the biggest problem came rumbling down, hit us and turned us upside down again. But this time the boat didn't come upright. This time it remained upside down. As I was held down in the water, I just felt cross and disappointed. Disappointed because there were so many things I wanted to do. While Matt was under water fighting for his life, his father, Radio, had also been swept overboard. What I remember next was standing up and seeing what I least wanted to see. I don't know why, but I knew straight away it was my father, lying face down in the water, just drifting away. That was the last I ever saw of him. As we flew back, looking out of the window, it was a scene of chaos. Some people were firing distress flares, desperate to be picked up. I think that was the first time that it really struck me how serious the whole scene had been. Tragically, Low Y was responsible for deaths in the Fastnet race. Some were washed overboard, others died trapped in their vessels. But many more died in life rafts that proved woefully inadequate for such awful conditions. Friends of mine who were in the storm and people I've met since then who have sailed round the world, all of them say they had never seen anything like the conditions they saw in this small area in the Irish Sea. This was wind and waves at their wildest. They defeated the best sailors in the world. But there is a wind that creates the biggest waves in the solar system. It's the fastest wind of them all. Here, on one of Hawaii's highest mountains, is the place to see it. But at a speed of four million miles per hour, you need specialist kit...
