(ˈmɛt əˌsɛn tər)

n.

the intersection between two vertical lines, one through the center of buoyancy of a hull in equilibrium, the other through the center of buoyancy when the hull is inclined slightly to one side or toward one end.

Ferreiro traces the pursuit of this emerging ship science through the work of key individuals, most notably Pierre Bouguer, the "father of naval architecture." The book also takes a topical approach, focusing on efforts to develop the major concepts of ship design, including the proper configuration and placement of masts and sails, hull resistance in water, hull displacement, buoyancy, the center of gravity, and the metacenter. Running through this history is the evolving process of naval architecture through the end of the eighteenth century, including the development and standardization of terminology, ship models and plans, and experimental techniques.
