In 2009, 55 giant bags of sand were dropped into the Atlantic Ocean, 100 miles southwest of London, to enhance the natural energy of waves. The Daily Mail reports the purpose of the project was to improve surfing conditions by increasing swells, on a one-of-a-kind reef, in the Northern Hemisphere. Officials found the bags shifted and created the potential for a dangerous undertow. Additional investigations found the man-made reef was creating hazardous rip tides for beach goers. At a cost of $5 million and meant to attract worldwide surfers, even the “locals” were complaining. Many contended the reef was creating waves that were too steep and broke too quickly for superb surfing. Those that built the reef are attempting to repair it.
