Dataset for Sea-Trial Data Processing and Manoeuvring Analysis of a Rigid Inflatable Boat (RIB) MITO 31

This dataset contains full-scale sea-trial data recorded for a Rigid Inflatable Boat (RIB) MITO 31, a two-stepped high-speed planing craft. The dataset includes raw IMU/GNSS and NMEA2000 log files, processed time histories, summary tables, environmental-condition metadata, figures, and Python scripts used for post-processing. The sea-trial data include three selected operating conditions: a zero-speed free-drift record, a high-speed straight-running seakeeping interval, and two turning manoeuvres. The processed quantities include pitch, roll, heading, velocity components, GNSS trajectory, engine RPM, acceleration components, yaw-rate quantities, and turning-circle parameters. The repository is organized into raw data, processed data, summary tables, metadata, processing scripts, and figures. The dataset can be reused for validation of numerical simulations, manoeuvring analysis, seakeeping analysis, signal-processing studies, and comparison with CFD or other prediction methods for high-speed planing craft.
