Abstract: A telescoping boat light-antenna for use on a vessel which is recessed below the level of the deck when not being utilized and is capable of being extended to a predetermined height above the deck through a telescoping motor assembly when being utilized as either a boat light or an antenna. The light-antenna includes a recessed cup below a base plate which supports the light lens below deck level when recessed therein in a non-utilized position and provides for extension of the telescoping tubing when the light-antenna is in a telescoped position. The twofold purpose of the light and antenna provides for military function in communications command and control of the vessel as well as safety at sea.
