This comprehensive book, Ship Hydrodynamics: Resistance, guides the student through the exploration of the principles, theories, and practical approaches behind ship resistance. The book was developed from lecture notes prepared for the course Ship Hydrodynamics – Resistance at ITU. Aimed particularly at students and also professionals in naval architecture, it bridges the gap between theoretical  knowledge and its real-world applications. Starting from the basics of ship resistance, the text delves into intricate details of dimensional analysis, components of resistance, model testing, computational and statistical methods and other related issues. Each chapter is structured to reflect weekly lecture content, ensuring clarity and systematic progression. With a strong focus on understanding physical and mathematical models, the book empowers readers basically to approach resistance prediction and understanding the physical nature of resistance problem. The book is packed with illustrative examples and problems for practice, and extensive references are included as well. Professor Gören’s expertise is reflected throughout this book, making it not just a reference textbook for students but also a practical guide for naval architects and marine engineers.
