The USS Mayflower was a screw tugboat constructed in 1866 at Chelsea, Massachusetts, by James Tetlow. She was the first U.S. Navy vessel to carry the name Mayflower. Designed for versatility, she featured a screw propulsion system characteristic of the post-Civil War era, enabling more efficient maneuvering compared to paddle steamers. Commissioned shortly after her construction, Mayflower departed from the Boston Navy Yard on February 16, 1866, and arrived at Norfolk, Virginia, on February 21. She was initially laid up in ordinary at Norfolk until 1870. Her first notable service was her participation in the 1870 expedition to Tehuantepec, Mexico, where she was tasked with surveying the isthmus for a potential inter-oceanic canal. Departing Hampton Roads on October 14, she reached Minatitlan, Mexico, on November 11. The survey mission provided valuable topographical data about Central America, and Mayflower returned to the Washington Navy Yard on May 25 of the following year. Subsequently, she served as a dispatch boat, operating along the Potomac River, Norfolk, Annapolis, and Washington, D.C. until her decommissioning on October 20, 1874. After repairs at Camden, New Jersey, she was recommissioned on May 11, 1876, and assigned to Annapolis as a training ship for midshipmen at the United States Naval Academy. Her role was critical in educating future naval officers in seamanship and naval operations. Mayflower remained in service until she was struck from the Navy list on September 23, 1892. She was decommissioned and sold to Thomas Butler & Co. of Boston, Massachusetts, on December 27, 1893. Throughout her career, Mayflower contributed to surveying efforts, coastal duties, and naval training, marking her as a versatile vessel of the late 19th century U.S. Navy.
