Archimedes derived the basic laws of fluid statics that are the fundamentals of hydrostatics today. In hydrostatic terminology, the gravitational and buoyancy forces are called restoring forces and are equivalent to the spring forces in a mass–damper–spring system. A 6‐DOF coupled analysis of the frequency‐dependent data can be done by using modal analysis. The chosen load condition or weight distribution will determine the heave, roll and pitch periods of a marine craft. The chapter presents methods for computation of the natural periods using coupled and decoupled equations in heave, roll and pitch. Seakeeping analyses should be performed to estimate seakeeping ability or seaworthiness, that is how well‐suited a marine craft is to conditions when underway. The chapter also presents methods for computation of the heave, roll and pitch responses in regular waves.
