Wyoming was an American wooden six-masted schooner built and completed in 1909 by the firm of Percy & Small in Bath, Maine. With a length of from jib-boom tip to spanker boom tip, Wyoming was the largest known wooden ship ever built. Because of her extreme length and wood construction, Wyoming tended to flex in heavy seas, which would cause the long planks to twist and buckle, thereby allowing sea water to intrude into the hold. Wyoming had to use pumps to keep her hold relatively free of water. In March 1924, she foundered in heavy seas and sank with the loss of all hands. Description Wyoming was designed by Bant Hanson with Miles M. Merry, the master builder for the Atlantic coastal trade, under the Percy and Small house flag with intended cargo being coal. Wyoming was overall, on deck, and between perpendiculars. She was wide, and had a draft of . Her gross register tonnage (GRT) was 3730.54, equivalent to an internal volume of . Her net register tonnage (NRT) was 3036.21, reflecting a cargo capacity of , determined by subtracting the volume consumed by the helm and crew quarters and other areas not suitable for cargo from her GRT. She had a deadweight tonnage (DWT) of 6,004 long tons, that is, the weight of the ship fully loaded, including the crew, cargo (6,000 tons), fuel, water and stores, less the weight of the ship when totally empty (4,000 tons). It could carry 6,000 long tons of coal. Wyoming was built of yellow pine with 6" planking and there were 90 diagonal iron cross-bracings on each side. Wyoming was equipped with a Hyde anchor windlass and a donkey steam engine to raise and lower sails, haul lines and perform other tasks. The steam engine was not used to power the ship, but permitted it to be sailed with a smaller crew of only 11 hands. She was named for the state of Wyoming because Wyoming Governor Bryant Butler Brooks (1907–1921) was one of the investors in the ship, which cost $175,000 in 1909 dollars. Another Percy & Small-built schooner, the five-masted Governor Brooks, was named after Brooks. History 1909 – 15 December. Launched at the Percy and Small Shipyard with its masts stepped.
