Performance and Special Trials are conducted on the first ship of each new class of ships built for the US Navy, and on ships of existing classes where major modifications have occurred. Performance trials include a series of extensive sea trials designed to obtain definitive data concerning the hydrodynamic capabilities of the ship. Special Trials are a series of unique trials carried out concurrently with Performance and Special Trials planning, agenda preparation, trials procedures, instrumentation calibration and installation, trial sites, data collection, and analysis and reporting are presented. Examples of the various types of definitive maneuvers used to evaluate ship performance are given. Finally, advances in instrumentation and data collection techniques which have occurred as a result of portable, small, high speed computers are presented.
