... better seakeeping. However, dynamics of such boats are rather complex. In this work, a 6-DOF dynamics model with engineering correlations for hydrodynamic forces is applied to simulate motions of an autonomous hydrofoil craft. Collision avoidance maneuvers based on introduction of a dynamic waypoint...

.... Fire Detection Fire detection is especially important on larger vessels with multiple accommodation spaces and the growing number of accessories that generate heat. Boats are now loaded with electronics and batteries in addition to the engines and control systems. Also, the new U.S. Coast Guard...

... The U.S. Coast Guard’s 154 foot Sentinel Class patrol craft (154WPC), also known as the Fast Response Cutter (FRC), replaces the well known and respected 110 foot Island Class patrol boat (110WPB). Increases in mission and operational capabilities, 110WPB to 154WPC, are discussed and presented...
