The accurate assessment of a ship-s dynamic behavior is essential for understanding its stability characteristics, particularly in response to free oscillations such as roll decay. This study presents the development and application of a compact, cost-effective inertial measurement system based on the Bosch BMX160 IMU sensor, integrated with a Raspberry Pi 4 single-board computer, for measuring ship model free oscillations both in water and in a controlled air environment. The system enables remote data acquisitio...

Catamarans are widely used in marine transport due to their advantages in stability and speed. However, their hydrodynamic performance is affected by the interaction between the two hulls, which creates complex interference phenomena influencing resistance and fuel consumption. Understanding and quantifying these interference effects is essential for optimizing catamaran, a key factor not only for operational efficiency and emissions reduction but also for achieving climate-resilient, energy-efficient marine trans...
