Maritime & Naval

Maritime Morse code is where the entire signaling tradition began. The first commercial telegraph cables crossed the Atlantic in the 1860s, and ship-to-ship Morse transmission was mandatory under SOLAS regulations until 1999 when GMDSS replaced it. Words like anchor, captain, harbor, vessel, lighthouse, and starboard all have direct operational meaning in maritime CW. Lighthouses around the world still flash Morse identifiers (Morro Castle, NC: dah-dit-dah-dit dit-dit-dah dit-dit). For sailors, ship hobbyists, and maritime historians, this category is the closest Morse gets to its working heritage.
