The design of the new 108‐ft yard patrol craft (YPs) for the U.S. Naval Academy is described from its beginnings as a senior midshipman design project, through its preliminary and contract design development at the U.S. Navy's small craft design team headquarters, Naval Sea Combat Systems Engineering Station, Norfolk, Virginia (NAVSEACOMBATSYSENGSTA‐Norfolk). During preliminary and contract design the Naval Academy Hydromechanics Laboratory (NAHL) provided experimental data to support NAVSEA‐COMBATSYSENGSTA‐Norfolk's design analyses in powering, seakeeping, and maneuvering. Several tradeoff studies of interest to patrol craft designers are presented. Major events in the detail design and construction of the first boat are described from both the designer's and the shipbuilder's points of view. The launching, builder's and sea trials of the first boat are described. A modification to provide an oceanographic research capability for the Academy's Oceanography Department is outlined. The model data acquired at NAHL and the full scale data acquired during sea trials provide an unusual opportunity for correlation analyses for small patrol craft.
