    Ship Stability is at the core of naval architecture. It is a beautiful topic involving elegant mathematics and precise computations. Most of the knowledge around ship design is built around the basic concepts of stability theory. Also, ship stability is the most straightforward problem in ship dynamics: no motion is considered, with no forces or moments acting over the boat except its weight, buoyancy, and heeling moment.
