Ship Motions - The Ultimate Guide

Six Different Motions of Ship- These six freedoms are divided into two categories: three translational degrees, and three rotational degrees. In this section, we will analyse the three translational degrees arising out of ship motions: 1. Heaving (Vertical translation – Z-axis) 2. Swaying (Transverse translation – Y-axis) 3. Surging (Longitudinal translation – X-axis) Translation refers to the motion of a body such that every point on it moves at the exact same speed. Along the three axes, we ob
