HMS Porpoise was a storeship constructed to a commercial design by John Henslow, the Surveyor of the Navy, and launched in 1798. The vessel was acquired by the Royal Navy shortly after her launch and commissioned in July 1798 under Lieutenant Walter Scott. She was built with the primary purpose of transporting essential supplies, notably a collection of trees and plants intended for Sir Joseph Banks in Australia. A distinctive feature of HMS Porpoise was the "garden cabin," a small, specially designed space measuring 6 feet by 12 feet located on the quarterdeck, where George Suttor tended the plants during the voyage. Her role in transporting botanical specimens was part of early efforts to establish scientific and agricultural links with Australia. The vessel's service was marked by several unsuccessful attempts to reach Australia, during which she was deemed unseaworthy. Despite her initial purpose, her journey was marred by difficulties, and she did not successfully fulfill her botanical transport mission. Subsequently, her identity was changed when the Navy renamed her Diligent in 1799. She was classified as an "armed ship," reflecting her fitted-out status, although specific armament details are not provided. HMS Porpoise (later Diligent) was sold in 1802, at the conclusion of the French Revolutionary Wars, marking the end of her brief but notable service. Her construction and mission highlight the era's maritime efforts in scientific exploration and the logistical challenges faced by ships operating in distant colonial waters. Her story underscores the importance of auxiliary vessels in supporting scientific and imperial endeavors during the late 18th and early 19th centuries.
