The NASA Marine Yacht Repeater displays essential navigation information from a range of NMEA-0183 enabled devices. The large LCD display is easy to read at a distance and over a wide viewing angle. For night viewing the characters glow red on a black background producing a very sharp image without compromising the crew\'s night vision. Selection of data and back-light intensity are performed using a waterproof wireless remote control unit. The weatherproof display is designed to mount on a mast or other structure on a vessel.
