Principles of Yacht Design/Особенности проектирования яхт

Книга на английском языке.
Principles of Yacht Design has established itself as the standard book on the subject for practising designers, naval architecture students and discerning boat owners, as well as the boatbuilding industry as a whole. This fourth edition is wholly revised and expanded and follows the design from scratch of a completely new 41 foot performance cruiser to demonstrate the practical application of yacht design theory. As such, it examines every aspect of the process of yacht and powerboat design.
