  • Publication number: 20080025033
    Abstract: What is disclosed is a vessel (1) provided with one or more light sources (3), wherein the vessel is at least partially made of an at least slightly light-transmitting material, and wherein said at least one light source is connected to the material in such a manner that the light is spread within the material. The advantage of the vessel is that the—usually supporting—material of which the vessel is built up, which material is already present anyway in some types of boats, such as inflatable boats, can be utilized in a multifunctional manner, so that it can be used as a light carrier or a light diffuser as well. As a result, the vessel attracts more attention, but it can also be used more effectively as a conspicuous, eye-catching craft, which makes it optimally suitable for use as, for example, an advertising craft or a warning buoy.
