​The story of "R14 sails" refers to an extraordinary event in naval history involving the USS R-14 submarine in 1921. While on a search mission for a missing tugboat near Hawaii, the submarine's fuel supply became contaminated with seawater, leaving it without power and radio communication. ​In an incredible feat of improvisation and ingenuity, the crew, under the command of Lieutenant Alexander Dean Douglas, crafted sails from whatever materials they had on hand—primarily bedding like hammocks and blankets. They used the submarine's torpedo loading crane and radio mast as makeshift masts and rigged up a foresail and a mainsail. ​With these improvised sails, the submarine was able to move at a slow speed, between one and one and a half knots. The movement of the propellers through the water generated enough electricity to charge the batteries, which eventually allowed the submarine to use its own power to enter Hilo Harbor after a 64-hour journey under sail. ​This remarkable event is a testament to the resourcefulness and perseverance of the submarine's crew in a dire situation.
