摘要

A floating raceway includes a raceway portion formed of a tough and flexible film material to define a space for accommodating water, and a floating bank portion surrounding the raceway portion for imparting buoyancy to the raceway portion and shutting off the interior of the raceway portion from the exterior. Therefore, the raceway stays afloat on the water surface to allow water in the raceway portion to be transported. The raceway portion can be set afloat on the water by way of the floating bank portion. Therefore, it can be advantageously employed to transport water. By a similar arrangement it is possible to provide a floating water storage tank so that a large amount of water can be made available at sea.
