Stability can exist when a vessel is rolling or trimming – it is the ability to
remain in stable equilibrium or otherwise. Hence there is a link between
Ship Stability and Ship Motion. Stability can also exist in ship structures via
the strength of the material from which they are built. A material may be
stressed or strained and not return to its initial form, thereby losing its stability.
Hence there is a link between Ship Stability and Ship Strength.
Another type of Ship Stability exists when dealing with course-headings
and course keeping. This is called Directional Stability. Examples of this are
given in Chapter 38, Interaction.
