“…At all course levels, instructors incorporate laboratory and field work, as appropriate, including rotating tank experiments (e.g., Illari et al, 2009) and observational measurements taken from short cruises in Chesapeake Bay on our Yard Patrol craft (Compton et al, 1987). A detailed description of each department course is available at http://www.usna.…”

“…During these trials, the YP showed herself to be highly maneuverable and stable. This, combined with the effectiveness of the noise control measures, resulted in a very comfortable boat" [15]. Noise and vibration data taken on the 80-ft. YPs, combined with expected source level changes, were used to predict that the noise criteria would be exceeded by approximately 10 to 15 dB.…”

Patrol boats are one of the most difficult of marine platforms to quiet. Due to their compact size, the high power density of their equipment, and unusually long operating periods, patrol boats have noise and vibration levels which often create special problems requiring unique or innovative control techniques. The problems and solutions are generally different than those typical of larger ships. Acceptable noise environments will only be achieved when regulatory bodies, owners/operators, designers and builders recognize the patrol craft's unique problems. In addition to the need for extensive and novel noise control treatments, it will always be necessary for all parties concerned to incorporate effective acoustical design practices into the overall program. This paper presents the noise criteria applied to accommodation areas, the extent of the habitability noise control program undertaken, noise control approaches and treatments, and resultant levels on four different classes of patrol craft ‐ the U.S. Coast Guard 95‐ft. Cape class patrol boat (WPB), U.S. Navy 120‐ft. torpedo weapon retriever (TWR), U.S. Navy 108‐ft. yard patrol boat (YP), and USCG 110‐ft. Island class patrol boat (WPB). These programs include a rehabilitation, a new design, the reconfiguration of a smaller craft to suit a particular mission, and a procurement under a parent craft concept, respectively. Many of the special problems, potential solutions, and shortfalls of current approaches will be underscored. The actual steps taken during the design, construction and testing of the craft will be featured. No attempt is made to present all viable noise control treatments for patrol craft, to detail the installed treatments, or to establish acceptance criteria.

In this paper, we present a comprehensive trajectory tracking framework for cooperative manipulation scenarios involving marine surface ships. Our experimental platform is a small boat equipped with six thrusters, but the technique presented here can be applied to a multiship manipulation scenario such as a group of autonomous tugboats transporting a disabled ship or unactuated barge. The primary challenges of this undertaking are as follows: (1) the actuators are unidirectional and experience saturation; (2) the hydrodynamics of the system are difficult to characterize; and (3) obtaining acceptable performance under field conditions (i.e., global positioning system errors, wind, waves, etc.) is arduous. To address these issues, we present a framework that includes trajectory generation, tracking control, and force allocation that, despite actuator limitations, results in asymptotically convergent trajectory tracking. In addition, the controller employs an adaptive feedback law to compensate for unknown-difficult to measure-hydrodynamic parameters. Field trials are conducted utilizing a 3-m vessel in a nearby estuary. Published
