USLHT Shubrick

USLHT Shubrick was a paddlewheel steamship built for United States Lighthouse Service in 1857. She was the first vessel built specifically as a lighthouse tender, the first steam-propelled lighthouse tender, and the first lighthouse tender on the Pacific Coast of the United States.

As one of the few armed government vessels on the west coast, Shubrick was put to a variety of uses. Most of her years were spent in placing and maintaining buoys, and building and supplying lighthouses. During the Pig War and the American Civil War she had minor military roles. She spent five years as a revenue cutter, enforcing customs regulations. She rescued mariners in distress and provided relief to flood victims.

After thirty years at sea, Shubrick was sold for scrap and broken up at San Francisco in 1886.

The United States gained a Pacific coast through the Oregon Treaty, which settled the boundary between the United States and the British possessions to the north in 1846, and the Treaty of Guadalupe Hidalgo which ended the Mexican-American War in 1848. This territorial expansion was reinforced by the California gold rush in 1849, and California statehood in 1850 which significantly increased maritime traffic on the west coast. In response, the United States Congress began to fund aids to navigation on the Pacific in 1852. By 1856 there were 23 lighthouses, but no lighthouse tenders to maintain them. Congress appropriated $60,000 on 18 August 1856 for a lighthouse tender for California.

Shubrick's hull was built of live and white oak. Her timbers were fastened with copper and iron nails. She was 140 feet (43 m) long, with a beam of 22 feet (6.7 m), and a draft of 9 feet (2.7 m). She displaced 305 tons.

Her 150 horsepower engine was built by James Murphy & Co. at its Fulton Iron Works in New York. The steeple-type engine had a single cylinder which was 50 inches (1.3 m) in diameter with a 48 inches (1.2 m) stroke. Her engine and machinery was reported to have cost $21,000. The engine drove paddlewheels on each side of the ship which were 19 feet (5.8 m) in diameter with a face of 9.6 feet (2.9 m). Steam was provided by a single vertical-tube boiler that was fired by three coal-burning furnaces.

She had two masts and was rigged as a brigantine.

Shubrick was built at the Philadelphia Navy Yard and was launched on 8 August 1857. Her sea trial took place on 4 November 1857. She reached a speed of 12 knots.
