Maine Maritime Museum in Bath will open a new exhibit, Wavelength: The Story of Signals at Sea, on Saturday, November 14. The exhibit explores the history of communications at sea, from flags, bells, and whistles to radio, radar, and GPS.

Wavelength will trace the evolution of maritime signals from optical to electronic, including a display of an early Marconi-era steamship’s radio room, along with vintage bells and whistles, lanterns, depth sounders, ship-to-shore, Loran, and other collection rarities. Visitors will be able to experience maritime communications through a variety of hands-on, interactive activities, including an engine-room telegraph and signal flag identification, along with demonstrations of actual Morse code transmissions from the gallery using period apparatus. The exhibit will be on view in The John G. Morse Gallery at Maine Maritime Museum from November 14 through May 15, 2016.

Wavelength: The Story of Signals at Sea is generously sponsored by the family of George C. Twombly and General Dynamics/Bath Iron Works with additional support from Atlantic Motorcar Center.
