High Quality Content by WIKIPEDIA articles! The Wyoming was a wooden six-masted schooner, the largest wooden schooner ever built. She was built and completed in 1909 by the firm of Percy & Small in Bath, Maine. The Wyoming was also one of the largest wooden ships ever built, the longest wooden ship ever built, 450 ft (140 m) from jibboom tip to spanker boom tip, and the last six-mast schooner built on the east coast of the US.Because of the extreme length of the Wyoming and its wood construction, it 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 (see Hogging and sagging). The Wyoming had to use pumps to keep its hold relatively free of water. In March 1924, it foundered in heavy seas and sank with the loss of all hands.
