Marine advertising vessel

A marine vessel comprising spaced, generally parallel hull members, a deck structure surmounting the hull members to define a floating vessel, a reticular display frame fitted along the deck centerline having a vertical bowmast rising from the bow, a vertical sternmast rising from the stern, a top beam extending fore and aft between the tops of the bow and stern masts, and a deck beam interconnecting the bow and stern masts just above the deck, the base of each of the bowmast and sternmast being rigidly secured to the deck substructure, the display frame extending a considerable distance above water line and providing a substantial rectangular area for mounting an advertising display visible from port and starboard sides of the vessel, the top of the display frame having support rails for mounting a light system for illuminating an advertising display surface, the advertising display being within the display frame at an angle of from 90° to 120° with respect to the deck as an aid to better visibility at greater distances of the display from shore.
