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. In the derivation of restoring forces and moments it will be distinguished between submersibles and surface vessels: underwater vehicles, and surface vessels. For a floating or submerged vessel, the restoring forces are determined by the volume of the displaced fluid, the location of the center of buoyancy (CB), the area of water plane and its associated moments. This chapter shows that how these quantities determine the heaving, rolling and pitching motions of a marine craft. Static stability considerations due to restoring forces are usually referred to as metacentric stability in the hydrostatic literature. The chosen load condition or weight distribution will determine the heave, roll and pitch periods of a marine craft.
