What is the best shape for a sailboat? How does turbulence affect a sailboat's movement through the water? Why do some keels have wings? Is it true that some sailboats can sail faster upwind than downwind? Authoritative yet accessible, The Physics of Sailing Explained is the perfect book for all those sailors who want to enhance their understanding and enjoyment of life at sea. It will enable cruisers and racers alike to better grasp how sails, keels, and hulls work together to keep boats afloat, and will sharpen their skills with a more subtle and thorough appreciation of why various boat design features are present and why certain tactics work in certain situations. Anderson outlines the science behind sailing in a way that anyone can understand and benefit from without having to trudge through a physics text or became a naval architect. Concepts are conveyed simply, concisely, and with many examples and illustrations. With the help of this invaluable book, sailors will be better prepared to handle any situations that might arise on the water.

Bryon D Anderson is a writer and scientist with a special interest in sail.

Breaking down the complicated concepts of speed, acceleration, torque, fluid mechanics, and surface physics, Physics of Sailing provides 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 scienti

Principles of Yacht Design has established itself as the standard book on the subject for practising designers, naval architecture students, discerning boat owners as well as the boatbuilding industry as a whole. The fifth edition is completely revised and expanded. It examines every aspect of the process of yacht and powerboat design. The new edition includes new findings from recent research in aero and hydrodynamics, as well as covering the most recent changes to building standards. The authors have used a newly built 41-foot performance cruiser to demonstrate the practical application of yacht design theory. This new edition includes photos of the building process and detailed explanations.

Here is a detailed study of the motive forces of a yacht written in clear and accessible terms. The author has the rare gift of enabling his readers to relate the nautical phenomena with which they are so familiar to a scientific explanation of how and why these occur. The first part covers downwind sailing, upwind sailing, sails, the hull, and the dynamic motion of a yacht. Part Two is devoted to more mathematical explanations of the same phenomena for those requiring a more scientific approach.

New analysis shows how Newton and Galileo provide a straightforward and useful explanation of sailing. According to Newton, the sail re-directs a mass of air of the apparent wind backwards to create a backward force (Force = ma). The reactive equal and opposite forward force pushes the sailboat ahead. According to Galileo a boat can sail downwind faster than the wind for the same reasons that it can sail upwind faster than the wind. Each tack is simply the mirror image of the other one. This is because in both situations the sailboat experiences a headwind, and the true wind is moving backwards relative to the boat. When sailing both upwind and downwind, the sail extracts momentum and energy from the true wind by slowing it down. That's it.

The first guide to design aimed at every sailor. The authors examine a range of boats, from a 14-foot dinghy to a 40-foot cruiser, a catamaran to an offshore singlehander, to show what makes hulls, keels, ballast, rudders, foils, masts, and sails work. Their explanations include state-of-the-art graphics, dynamic charts, and photographs.
