Abstract
The pneumatic float according to the invention comprises an airtight outer skin ( ), which can be inflated with compressed air via a valve ( ). Webs ( ) extend essentially over the entire length of the float, which are joined to the outer skin ( ) along the lines ( ) and on the one hand divide the inside of the float into intercommunicating chambers ( ), and on the other hand give the float the desired contours ( ), stability and stability against bending. The webs can comprise single or multiple layers of low-stretch woven material or plastics material foils. To improve directional stability in operation and as a protection against damage to the outer skin ( ) the float has a keel rail ( ), for instance comprising plastics material, and glued on. To avoid the Coanda effect two side rails ( ) are attached in a similar manner.
