The USFC (later USFS) Grampus was a wooden schooner designed for fisheries research, commissioned in 1886 and in service until 1917. Built largely of white oak with some white pine, she measured approximately 90 feet in length overall. Her hull was notably deeper—by about 18 to 24 inches—than traditional New England fishing schooners, enhancing her stability and seaworthiness. The vessel featured a more streamlined stern and a straight stem, with a shorter foremast compared to the mainmast, allowing for more efficient sail handling and higher speeds. Her rig included a foresail, staysails, gaff topsails, and a balloon jib, combined with auxiliary sail rigging that improved maneuverability and safety. Grampus’s design incorporated a revolutionary approach to schooner construction, emphasizing speed, safety, and seaworthiness. She was equipped with a steam windlass powered by a 35-horsepower engine, complete with a boiler, steam pump, and water tanks, to operate her gear effectively. Her well was pyramidal, about 16 feet long, with circulation holes to keep fish alive during transport and study. The vessel also carried a laboratory, fishing gear for trawling, gillnetting, seining, dredging, and jigging, as well as equipment to collect fish eggs, plankton, and environmental data such as temperature and depth. Throughout her career, Grampus contributed significantly to fisheries science, particularly in understanding the mackerel fishery, tilefish populations, and fish migration patterns along the U.S. East Coast, Gulf of Mexico, and North Atlantic. She was instrumental in experimental fish culture efforts and in testing European beam trawling methods to enhance American fishing industries. Her modifications and advanced design influenced subsequent commercial schooners, establishing her as a pioneering vessel in both scientific research and maritime engineering. After over three decades of service, she was decommissioned and sold in 1918 due to hull defects and obsolescence.
