A water borne billboard is provided in the form of a marine vessel designed to accommodate a billboard for display along heavily populated coastlines. The billboard is two-sided, both side being visible to observers on the coastline by either rotating the pivotally mounted billboard while the vessel is moving or reversing the direction of the vessel. The vessel is operated by one or more operators and may be designed to conceal the operators from view by the observers. The vessel is propelled by conventional means such as an internal combustion engine or an electric motor.
