Abstract: A system for remote activation of multiple marine electronic appliances, whereby all the appliances within the system may be activated and deactivated at once, or whereby different appliances within the system may be remotely activated and deactivated. The system includes a receiver connected to the circuit for an appliance and a transmitter set to transmit signals, which are received by the receiver and activate or deactivate the connected appliance. The appliances include boat lights, dock lights, pier lights and the like.

Abstract: Disclosed is a combination marine accessory assembly for conveniently installing a plurality of marine accessories. The assembly contains, within a single housing, a plurality of marine accessories such as lights and horns. The accessories are mounted within a single housing, and the housing is installed on the open deck of a boat. The housing of the invention further provides protection for the marine accessories.

Abstract: Disclosed is a boat light having a status indicator. The status indicator activates when the boat light is illuminated, and the status indicator may be viewed by the operator of the boat under any lighting conditions. The boat light comprises a housing, a lens, an illumination source emitting light through the lens; and a status indicator that emits light when the illumination source emits light.

Abstract: Disclosed is a multidirectional docking light where the direction of the light beam may be adjusted even after installation, and where the light may be simultaneously aimed in more than one direction.

Abstract: A combination marine horn and bow light is provided. According to the invention, a single unit houses a bow light assembly affixed to a housing which contains a sound emitting portion of the horn. The bow light and sound emitting portion of the horn are preferably mounted on the top surface of a boat bow deck. The horn is installed below the bow deck surface. The entire unit is powered by a single electrical supply. Alternatively, separate bow light and horn units may be affixed to the deck or hull sidewalls. In this embodiment, each bow light would have a separate colored lens cover. In a further embodiment, for either deck or sidewall mounting, the light and horn combination, including the sound emitting and sound producing portions, are all mounted on the exterior of the vessel.

Abstract: An articulated light head for navigational lights on motor boats. The light head incorporates a movable stem plate within an articulator base for manual positioning of the navigational light with respect to its supporting conventional hull pole as attached to the hull of the boat. The movable stem plate is frictionally secured between a stem plate trapper and the articulator base. A light base is fitted on top of the articulator base enclosing both the movable stem plate and stem plate trapper within the light head. A navigation light is supported by the light base and powered by electrical current directed through the light head. The navigation light is protected by a dome which fits over the light base.

Abstract: An apparatus, according to the invention, detects the relative speed of the apparatus with respect to the fluid into which it extends. The apparatus includes a streamlined body portion having an upper end, a lower end, a front edge, a back edge, and a pair of sides. A conduit extends through the body portion and is exposed to the fluid at an orifice located beneath the fluid line. The other end of the conduit is coupled to a pressure transducer which produces an output proportional to the pressure acting on the orifice and thus proportional to the speed of the apparatus relative to the fluid. This apparatus can be connected to an appropriate speedometer and is particularly useful for measuring the speed of a watercraft to which the apparatus is mounted.

Abstract: A marine speedometer system is disclosed which utilizes a short pitot tube or air column. The speedometer system includes an inlet having a short air column, a transducer, a control circuit, and a display. The electric signal from the transducer is representative of the pressure in the short air column. The control circuit preferably utilizes a microprocessor and a look-up table to generate a display signal in response to an electric signal from the transducer. The look-up table includes T-Buoy values and count values. The count values are used to drive a frequency signal for an air core meter. The display provides a needle and a metered background which is easy to read. The microprocessor is coupled to receive calibrate up and calibrate down signals. The microprocessor causes the needle to jump when it receives a signal to provide feedback to the driver. The microprocessor includes an auto zero subroutine which automatically calibrates the speedometer at start up.
