The Allianz Arena stadium is commonly referred to as “Schlauchboot” (= Inflatable Boats).
Some inflatable boats have been designed to be disassembled and packed into in a small volume, so they can easily stored and transported to water when needed. This feature allows such boats to be used as liferafts for larger boats or aircraft, and for travel or recreational purposes.
An inflatable boat is a lightweight inflatable boat constructed with its sides and bow made of flexible tubes containing pressurised gas.
