Physics of Sailing
John Kimballprovides a lively, easily accessible introduction to the basic science
underlying the sport of sailing. It illustrates the many ways physics
can be used to understand the principles of sailboat propulsion and how a
scientific understanding of the boat, wind, and water can lead to more
skillful sailing.
After
a brief but insightful tour of the history of sailing, the book
explores the physics involved in making faster sailing crafts for both
upwind and downwind sailing, including Newton’s impact theory of fluid
resistance and lift and drag phenomena. It compares possible sail
shapes, presents measurements of hull smoothness, and describes wind
turbulence, the nature of water waves, and the structure of wakes. Using
the physics of optics, the author also explains the connection between
water’s appearance and the wind. Along with a glossary of sailing terms,
he includes many examples throughout to illustrate the concepts in
practice.
Avoiding
unnecessary formalisms, this book skillfully applies the principles of
fluid mechanics to sailboat technology and the art of sailing. It should
help you become a more knowledgeable sailor.
