Even as a child, Achim Schlöffel dreamed of one day diving through the English Channel. For decades, such an undertaking was out of question – the technical resources were simply not yet available. Achim, however, had been planning this venture for a long time – and wanted to set a his world record.
In 2012, the time had come. For the longest dive in history. After a net dive time of 7 hours and 20 minutes, plus the decompression phase of 160 minutes, the whole endeavor took about 10 hours. 70 kilometers of diving in mostly single-digit temperatures, sometimes only centimeters of visibility, and an infernal noise throughout the whole dive, threatened by ship propellers and their noise in the world’s busiest shipping route.
