They had designed a collapsible sporting canoe, effective for both shallow water and deep, rougher seas, called a Folbot. A British officer, Major Roger Courtney, discovered it paddling the length of the Danube on his honeymoon, and he went on to organize a unit of the craft to raid Mediterranean ports. It caught the eye of the legendary founder of the Special Air Service, Colonel David Stirling, and he brought it into the SAS as its Folboat Section, carried out many brilliant operations.
