Naval architecture is an interesting field that encompasses the design, construction, and maintenance of various types of watercraft, including ships, boats, submarines, and offshore structures. It combines principles of engineering, physics, and design to create vessels that are safe, efficient, and seaworthy. Naval architects are responsible for designing the shape and structure of the ship's hull, determining stability and buoyancy, selecting propulsion systems, and complying with regulations and safety standards. They use advanced computer-aided design software (CAD) and perform in-depth analyzes to optimize vessel performance, taking into account factors such as hydrodynamics, structural integrity, and stability under various sea conditions. With their comprehensive understanding of the marine environment, naval architects play a critical role in developing innovative and sustainable solutions for the maritime industry.The objective of this book is to provide a comprehensive and in-depth understanding of the principles, theories, and practices associated with the design, construction, and operation of ships and other watercraft.
