SS Great Republic was a sidewheel steamship and the largest passenger liner on the US west coast when it ran aground near the mouth of the Columbia River, on Sand Island, south of Ilwaco, Washington, in 1879, in a region of frequent wrecks known as the Graveyard of the Pacific.

The Great Republic was launched from Henry Steers's ship-yard (see George Steers and Co), at Greenpoint, Long Island, on Thursday, November 8, 1866, and was the largest ship of any kind that at that date had ever been built in USA for commercial purposes. She was the first of the ships built by Pacific Mail Steamship Company for the new line between San Francisco and China, China Line, and was 380 feet (120 m) long, 50 feet (15 m) wide and 31 feet 6 inches deep in hold.
Her frame timbers were of white and live oak, fastened with copper and iron, and braced with straps of iron five inches wide and seven-eights of an inch thick, crossing each other diagonally every four feet. The inner planking was also double-strapped, and outside of the iron strapping was a double planking of Georgia yellow pine. The whole was thoroughly braced, and bolted together with three-nails of locust, iron, and composition spikes, and copper bolts.
The Great Republic had three masts, and was full ship-rigged, her foremast, however being the highest of the three, and her mizzenmast the shortest. She had three full decks, with an orlop deck fore and aft, extending to the engine bulk-head. She had four stout, water-tight bulk heads, dividing the hold into five separate compartments.[1]
Immediately after the launch the steamer was taken to the wharf of the Novelty Iron Works (New-York), at the foot of Twelfth-street, where she received her machinery, after being copper-bottomed at the Erie Basin Dock. It took 21 months to build her engines and put them in place. Steam was supplied to the cylinder by four horizontal tubular boilers, each heated by four furnaces, their grates having a surface of 560 square feet (52 m2). The heating surface presented to the action of the furnaces was 15,100 square feet (1,400 m2). The paddle-wheels were 40 feet (12 m) in diameter, having a face of 12 feet (3.7 m), each wheel being provided with 34 onk buckets.
The only accident at her launch was the loss of two anchors, the cables breaking the ship was hove to in the river. She was arranged for 20 per cent more power than the other large vessels then in the company's fleet, and was built to make from 15 to 20 knots an hour. Her register tonnage was 3,881 tons, the same as the SS America and the SS Japan.
Great Republic eventually proved unprofitable in the China trade and was sold in 1878 to P. B. Cornwall for service along the U.S. Pacific coast.
On April 19, 1879, a clear and calm night, the vessel was loaded with over 1000 passengers and crew, after departing Portland, Oregon, for San Francisco. After crossing the Columbia Bar at high tide, the pilot failed to heed the captain's warnings and ran aground on Sand Island.
Stranded on sand in a falling tide with a storm approaching, the captain evacuated the 896 passengers to Astoria, Oregon, on local boats. Crew remained aboard to re-float the vessel, but storm-driven waves began breaking up the hull, and they abandoned ship. The last boat to leave overturned, casting 14 men into the water, resulting in the death of eleven. Waves shortly rendered the vessel a total loss, though parts of the wreckage remained visible at low tide for many years.
Discovery of the wreck occurred in 1986, by a diver working to free a snagged fishing net. Following discovery the vessel was believed to be the Isabella, lost in 1830, carrying cargo to the Hudson Bay outpost at Fort Vancouver. However, later analysis of the wrecks planking wood, proven to be American Yellow Pine, as well as the size of the wreck, suggests it is instead the Great Republic. The book titled Pacific Graveyard, actually states that the SS Great Republic left San francisco in the spring of 1879 and arrived off the mouth of the Columbia at midnight on the 18th of April, and was actually on the way to Portland when it ran aground on Sand Island and was lost. 11 of the crew drowned in a life boat the next day while departing the crumbling ship.
