Falls of Clyde is the last surviving iron-hulled, four-masted full-rigged ship, and the only remaining sail-driven oil tanker. Designated a U.S. National Historic Landmark in 1989, she is now a museum ship in Honolulu, but her condition has deteriorated. She is currently not open to the public. In September 2008, ownership was transferred to a new nonprofit organization, the Friends of Falls of Clyde. Efforts to raise $1.5 million to get the ship into drydock did not succeed. In November 2021 HDOT accepted a bid from Save Falls of Clyde – International (FOCI) to transport the ship to Scotland for restoration. History Russell and Company built Falls of Clyde in Port Glasgow, Renfrewshire, Scotland. She was launched as the first of nine iron-hulled four-masted ships for Wright and Breakenridge's Falls Line. She was named after the Falls of Clyde, a group of waterfalls on the River Clyde, and built to the highest standard for general worldwide trade, Lloyd's Register A-1. Her maiden voyage took her to Karachi, then in British India, and her first six years were spent engaged in the India trade. She then became a tramp pursuing general cargo such as lumber, jute, cement, and wheat from ports in Australia, California, India, New Zealand, and the British Isles. After twenty-one years as a British merchant ship, Falls of Clyde was bought for US$25,000 by Captain William Matson of the Matson Navigation Company, taken to Honolulu in 1899, and registered under the Hawaiian flag. When the Republic of Hawaii was annexed by the United States in 1900, it took a special act of the United States Congress to secure the foreign-built ship the right to sail as an American flag vessel. To economize on crew, Matson rigged Falls of Clyde down as a barque, replacing the five yards on her (jigger) mast with two more easily managed fore-and-aft sails. At the same time, he added a deckhouse, charthouse, and rearranged the after quarters to accommodate paying passengers. From 1899 to 1907, she made over sixty voyages between Hilo, Hawaii, and San Francisco, California, carrying general merchandise west, sugar east, and passengers both ways. She developed a reputation as a handy, fast, and commodious vessel, averaging 17 days each way on her voyages. In 1907, the Associated Oil Company (later Tidewater Oil) bought Falls of Clyde and converted her to a bulk oil tanker with a capacity of . Ten
