A tube is a water sports device in the form of an inflatable ring or mat. The tube is pulled from the boat by means of a rope. The boat driver makes turns with the boat so that the tube glides over its own waves. The speed is adjusted to the wishes of the guests. Or how about a sofa tube? The sofa is 2 way suitable and offers place for 2-3 persons. In the curves the sofa accelerates enormously and flies over the water. Fun is guaranteed!
