Hall Brothers Ship BuildersHall Brothers designed and built some of the finest sailing ships ever constructed on the Pacific coast. Isaac, Winslow and Henry Knox Hall acquired their shipbuilding training at the center of America's boatbuilding industry in Cohasset Massachusetts, during the 1840's. Following the Gold Rush of 1849, Winslow Hall migrated to San Francisco. In 1863, he built the Sarah Louise, which was the first Hall vessel to be launched from the West coast.
