In the context of naval architecture, "hydrostatics" refers to the study of the buoyant forces and attendant properties which are involved in supporting a floating body at rest in calm or flat water. It also covers the similar phenomenon of liquid in a container. This is distinguished from "hydrodynamics" which involves fluid flow and time rates.

Extensions into the territory of hydrodynamics can be made using principles derived from hydrostatic analysis when forces arising from fluid flow are known to be relatively minor. Two examples of this are:

Applying hydrostatic principles to multiple-waterplane systems allows the liquid in tanks to contribute to the forces involved in modeling a floating ship. Taking this a step further, the ground can be modeled as a very dense liquid and hydrostatic forces can also be generated from it when the ship is aground.

Bending moments can also be derived by integrating the opposed buoyancy and weight forces over the length of a ship. This is known as "longitudinal strength" analysis and is usually associated with hydrostatics.

As the "General HydroStatics" computing system, GHS does all of these.

While GHS was developed specifically to address the kind of hydrostatics encountered in naval architecture, ship operation and marine salvage, it is not restricted to these fields. Examples of other applications are,
