Abstract

Concerning to the ship, it is very important to improve the investigation of the effect of the free surfaces due to fluid weigths in the transverse and longitudinal stability. The changes in parameters as metacentric height, heel and trim, roll and pitch, and the GZ arm for large angles of roll, are considered, and also, a correction to the mean draught for displacement purposes. Thinking in the ship's master, and in order to get a rigorous information of the free surface, this information has been covered with real data from some ships, with the final objetive of developing a practical method. 1 Introduction It is known that the free surfaces of the fluids affect the transverse and longitudinal stability of the ship. However, the co
